6900 Series 40 Gigabit Ethernet Interface Module for Cisco 6500 Series

March 3 2015 , Written by Cisco & Cisco Router, Network Switch Published on #IT, #Technology

Do you know something about the Cisco Catalyst 6900 Series 40 Gigabit Ethernet Interface Module for Cisco Catalyst 6500 Series Switches? Such as Cisco WS-X6904-40G-2T.

The module is designed to meet the increasing demand for aggregation of 10 Gigabit Ethernet on campus and data center, as well as for high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet transport in the core.

Each port can accept a 40 Gigabit Ethernet C Form-Factor Pluggable (CFP) optics module or be converted to four ports of 10 Gigabit Ethernet with a FourX adapter, enabling customers to deploy 10 Gigabit Ethernet to meet current needs and be ready to transition to 40 Gigabit Ethernet without any disruption. The module can also be used in mixed mode, where one side of the card uses two CFP modules for 2 times 40 Gigabit Ethernet ports and the other side uses two FourX adapters for 8 times 10 Gigabit Ethernet ports.

The Cisco Catalyst 6900 Series 4-Port 40 Gigabit Ethernet Fiber Module is compatible only with Cisco Catalyst 6500 Supervisor Engine 2T.

Cisco Catalyst 6900 Series 4-port 40 Gigabit Ethernet Fiber Module can operate in a number of modes. Performance mode enables 80 Gigabit Ethernet performance by using two ports without oversubscription. In Oversubscribed mode, the module uses four ports with 2:1 oversubscription.

The 4-Port 40 Gigabit Ethernet Fiber Module provides up to 44 x 40 Gigabit Ethernet Fiber ports in a single Cisco Catalyst 6513-E chassis and 88 x 40 Gigabit Ethernet ports in a Cisco Catalyst 6500 Virtual Switching System (VSS) 4T. The module has two 40-Gbps connections (for a total of 80 Gbps) to the 2-Tbps switch fabric of the Cisco Catalyst Supervisor Engine 2T, providing 2:1 oversubscription when all four ports of 40 Gigabit Ethernet or 16 ports of 10 Gigabit Ethernet ports are active.

Cisco Catalyst 6904 modules support two types of CFP optics: CFP-40G-LR4 and CFP-40G-SR4, providing operational distances of up to 10-km over single-mode fiber and 100m over OM3 multimode fiber, respectively. FourX adapters support a variety of Small Form-Factor Pluggable Plus (SFP+) optics

Have a Look at Cisco Multigigabit Ethernet Switches

Multigigabit Ethernet Technology Supports New Intermediate Network Speeds

Multigigabit-Ethernet-Technology-Supports-New-Intermediate-.jpg

 

Benefits-Multigigabit Ethernet Technology

• Increase network bandwidth and speed without running multiple cables between switches and access points.

• Lower operational costs by getting more performance out of existing cabling infrastructure.

• Power devices that require up to 60W, at speeds over 1 Gbps, even at 10G Base-T rates.

Cisco-Catalyst-3560-CX-Compact-Switch-Deploy-in-a-Snap.jpg

Network needs are changing quickly. Thanks to evolving wireless standards and the rising number of wireless devices, keeping up with data rates and growing traffic can be a challenge. Your traditional Ethernet infrastructure can support speeds up to 1 Gigabit per second (Gbps), but competing today requires much more capacity. One option is completely replacing your legacy cabling infrastructure and upgrading your hardware. But wouldn’t it be better to increase network speed and traffic capacity in a way that’s quick, inexpensive, and efficient?

 

Cisco’s new Multigigabit Ethernet switches offer just that: an easy-to-deploy, budget-friendly solution that allows you to increase network speed and bandwidth using your existing cables. By partnering with other industry leaders to form the NBASE-T Alliance, Cisco uses NBASE-T technology to help you get more out of your existing infrastructure. Save time and money by avoiding upgrades and extending the life of your installed cable plants. And discover the benefits of meeting consumer demand for increased bandwidth and speeds without a large initial investment.

Multigigabit Ethernet technology uses capabilities in your existing cabling infrastructure to meet bandwidth requirements and provide up to five times the performance. The technology enables intermediate data rates of 2.5 and 5 Gbps to ease the jump between traditional rates of 1 Gbps  and 10 Gbps. These intermediate rates run on the majority of installed cables and preserve legacy UTP wiring, which is good for 802.11ac wireless LAN applications.

The technology also supports Power over Ethernet (PoE) forms, including PoE+ and UPOE. Cisco Multigigabit Ethernet switches help you avoid having to run multiple cables between switches and access points and let your networks welcome next-generation traffic speeds and data rates.

As part of our next-generation architecture, Multigigabit Ethernet switches will be supported on multiple Cisco Catalyst platforms:

• Cisco Catalyst 4500E Series Switches: Multigigabit Ethernet technology will be introduced in the form of a new E-Series line card compatible with Supervisor Engine 8-E and beyond.

• Cisco Catalyst 3850 Series Switches: New 24-port and 48-port switches will support Multigigabit technology.

• Cisco Catalyst Compact Switches: A new 8-port switch will support Multigigabit technology.

More about Cisco’s New Compact Switch-Catalyst 3560-CX and 2960-CX Series

Have-a-Look-at-Cisco-Multigigabit-Ethernet-Switches.jpg

An effective work environment encourages collaboration. That often means tearing down office walls to create open workspaces. Doing that is now simpler and less costly, thanks to Cisco’s next generation of compact switches, the Cisco Catalyst 3560-CX and 2960-CX Series.

With their quiet, fan-less design, the switches create many possibilities for designing workspaces. They can reside nearly anywhere outside your wiring closet. Install them in carpeted areas such as offices, conference rooms, classrooms, and retail stores for quick, flexible connections. Rearrange rooms and floors without changing your cabling infrastructure.

Cisco Catalyst 3560-CX Compact Switch

Deploy in a Snap

• Transform your workspaces without cabling hassles and expenses

• Locate switches nearly anywhere, outside your wiring closet

• Deploy Internet of Things (IoT) devices in your enterprise

• Replace your hubs, simplify switch management, and enhance security

• Aggregate gigabit Wi-Fi traffic flows with 10-Gbps uplinks

Cisco-Catalyst-3560-CX-Compact-Switch.png

Consolidate cabling for big savings. Rather than running multiple Ethernet cables from endpoints like IP phones and Wi-Fi access points to a wiring closet, you just connect devices over a few feet of cabling to a nearby 3560-CX or 2960-CX switch. Then connect the compact switch to the wiring closet with a single Ethernet or fiber cable. Using this setup, a 200-room hotel using compact switches in guest rooms can eliminate up to 30 kilometers of cables. And a five-story shopping complex can eliminate about 7.5 kilometers of cable.

Note: 4:1 consolidation of cables, cable reduction of 3x100m for each customer service station. Assume 10 customer service stations per floor. Assume average cable run is 50m across all customer service stations, leads to 300m * 50 * 0.5 = 7,500m total cable reduction.

The Cisco Catalyst 3560-CX and 2960-CX switches enable you to bring sensors, LED lights, building controllers, and other IoT devices onto the network using Power over Ethernet (PoE). The many features and controls offered by these PoE switches make them run more efficiently and reliably. For example, Cisco Perpetual PoE continues powering endpoints even during a switch boot, maximizing uptime. So there’s no need for backup power. The switches provide up to 240 watts of power for PoE devices − twice the capacity of current switches.

For simplified management, these switches have the option to run in Cisco Instant Access mode. Instant Access provides a single point of operation and management for your campus networks. And they support Cisco Plug and Play (PnP) technology, which automates network device deployments.

The Cisco Catalyst compact switches support the full suite of Cisco Catalyst feature set for enterprise-class security and reliability. Cisco TrustSec and other advanced access control features protect against man-in-the-middle attacks and keep your Cisco Catalyst environment secure.

What Items You Need When Ordering a Cisco Aironet 1530 Outdoor AP?

January 27 2015 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

If you want to order a Cisco Aironet 1530, do you know what basic item you will get?

The body access point, power supply, Antennas, and software….That’s not enough.

 A fully operational system requires at least the following items: Access point, Power source, Antennas: 2.4 GHz, 5 GHz, or dual band (Cisco Aironet 1532E Outdoor Access Point only), Mounting bracket, Software selection.

Cisco-Aironet-1530-AP.jpg

Note that accessories are available as configurable options and as spares. An equal sign (=) at the end of the part number indicates that the part is a spare: for example, AIR-PWRINJ1500-2=.

Basically, the Cisco Aironet 1530 Series is available in two models:

● Cisco Aironet 1532I (internal antennas): The Cisco Aironet 1532I Outdoor Access Point is a low-profile, lightweight model in the Cisco Aironet 1530 Series. The smaller size and sleeker look helps it blend in with the surrounding environment. The Cisco Aironet 1532I access points are dual-radio systems with internal antennas and comply with IEEE 802.11b/g/n (2.4 GHz) and 802.11a/n (5 GHz) standards. The 2.4-GHz radio is a 3x3 multiple-input and multiple-output (MIMO) radio that supports up to three spatial streams. The 5-GHz radio is a 2x3 MIMO radio that supports two spatial streams.

● Cisco Aironet 1532E (external antennas): The Cisco Aironet 1532E Outdoor Access Point is also a low-profile and lightweight model, but it supports a flexible radio coverage area through the use of external antennas. With the unique Cisco Flexible Antenna Port technology, the antenna ports can be software configured for dual-band or single-band operation.

40/100 Gigabit Ethernet for Virtualized Data Center and Campus Networks

January 22 2015 , Written by Cisco & Cisco Router, Network Switch Published on #Networking

It is difficult to achieve optimal performance of your data center and networks, especially in a virtualized environment. Fortunately, effective implementation of 40/100 Gigabit Ethernet (GbE) can help pave the way for a fully functional virtualized network. 

In the following guide it explores the benefits of 40/100 GbE implementation in a virtualized environment and how it can maximize existing infrastructure investments.

40/100GbE is rapidly gaining traction as a key foundation for building the next generation of virtualized data center and campus environments. The 40/100GbE-based architecture for virtualized data center and campus is illustrated in the paper. IT managers are increasingly aware of the benefits and advantages1 offered by 40/100GbE as well as its promise as an interconnect option among data centers and commercial buildings in the campus.

On the economic side, barriers to entry in the 40/100GbE space continue to fall. Capital investment in 10GbE networks today can be protected when upgrading to 40/100GbE networks in the future. The Ethernet switching and fiber cabling examples in this paper illustrate:

• 55 percent2 of on switching equipment can be protected

• 57 percent3 of investment on fiber cabling can be preserved

On the availability side, more vendors have supplied solutions for the 40/100GbE ecosystem, and a number of multi-vendor interoperability events on 40/100GbE technology have been hosted by the Ethernet Alliance? With both Cisco? and CommScope? Actively participating. So, early adoption anxieties over locked-in vendor relationships have evaporated. The greater availability from multiple vendors and declining deployment costs due to broader adoption in the marketplace make 40/100GbE infrastructure a sound and prudent investment, both for today and tomorrow.

The increased traction of 40/100GbE has led to its best practice status as the standard for the next generation of high-bandwidth virtualized applications. This adoption has been fueled by both its superior performance and economic benefits in virtualized environments.

40/100GbE based architecture for virtualized Data Center and campus

40-100GbE-based-architecture-for-virtualized-Data-Center-.jpg

Virtualized Data Center

True data center virtualization is end-to-end virtualization, including server virtualization, storage virtualization, and network virtualization, and can result in many diverse benefits. Virtual machines and networks can be quickly and nimbly deployed. Their energy efficiency and capacity can dynamically scale to meet the demands of variable workloads without wasting resources. Disaster recovery is faster, and both initial and ongoing costs can be lower than those of traditional non-virtualized approaches.

In the journey to the virtualized data center and cloud, data center managers face a number of design and operational challenges. One of the most conspicuous challenges for network design is to provide enough bandwidth for the applications of today and the foreseeable future. With converged network technologies, 10GbE, which is becoming a de facto choice for server access networks, can be a good choice for a storage access network as well. Given 10GbE at the access layer, 40/100GbE is recommended for aggregation and core layers of networks in data centers, and this is where 40/100GbE removes the constraints that have previously prevented virtualized data centers from fulfilling their maximum potential.

 

Virtualized Campus

Video is a strongly growing application in campus networks. Video applications are more than just video conferencing or video streaming. Enterprise video applications include desktop high definition video, video phone, enterprise TV, IP video surveillance and other video generation and sharing. Bring your own device (BYOD) is another emerging trend in the campus network. Video, voice, data and BYOD put pressure on a campus’s distribution and core networks.

Compared to traditional layer 2 and 3 network design in the campus, the core and distribution networks can be virtualized by using Virtual Switching System (VSS) with Cisco Catalyst 6500 series switches. VSS is a network system virtualization technology that pools two or more Cisco Catalyst 6500 Series Switches into a virtual one. A VSS scales system bandwidth capacity with automatic load sharing. A VSS increases operational efficiency by simplifying the network and reducing switch management overhead by at least 50 percent. A VSS boosts nonstop communications with no disruption to applications. A VSS enhances existing multilayer switching architecture without fundamentally changing the architecture, resulting in ease of adoption and migration of the technology.

 

Ecosystem

A list of examples of 40/100GbE Ethernet switching and cabling solutions from Cisco and CommScope.

40/100GbE ecosystem examples

 40-100GbE-Ecosystem-Examples.jpg

The new Cisco Catalyst 6900 Series 4-Port 40GbE Fiber Module (WS-X6904-40G) for the Cisco Catalyst 6500 Series Switches was developed for deployment in the enterprise campus distribution layer and core layer, in traditional data centers with 10 Gigabit aggregation, and in metro-Ethernet-based data center interconnections, as well as in multipurpose service provider networks, which require high-performance data throughput coupled with security, manageability, virtualization, and quality of service.

The WS-X6904-40G module supports 10GbE and 40GbE interfaces. Figure 2 shows the 10GbE and 40GbE interfaces of Cisco Catalyst 6500 series switches. This new module is the only solution that supports both connections in a single format, for flexible migration. There are also many other new and exciting capabilities unique to the WS X6904-40G module, such as CTS (Cisco Trust Sec) for end-to-end role-based security deployment using SGT (Security Group Tagging) and SGACL (Security Group Access Control List) and link-by-link encryption based on IEEE 802.1AE MACsec (MAC based Security) standard, VNTag (Virtual Network Tag), and extensive quality of services features. The 40GbE Fiber Module is a perfect choice for forming a campus core network by interconnecting the physical switches of a VSS in core/distribution layer networks in the campus. It also can be utilized to connect access switches to a VSS at the distribution layer of the campus network. Users are deploying this module today and using it for four 10GbE links until they really need a true 40GbE channel.

Cisco Catalyst 10GbE and 40GbE Fiber Modules and optical transceivers

10GbE-and-40GbE-interfaces-of-Cisco-Catalyst-6500-series-sw.png

CommScope SYSTIMAX? InstaPATCH? 360 Pre-Terminated Fiber Solutions enable network operations in the data center at the current 10GbE speed of today, while provisioning for eventual upgrades to 40GbE and/or 100GbE. These solutions were tested, qualified and demonstrated in multi-vendor closed-door and open-to-public environments at both transceiver and system levels.4 Results repeatedly demonstrated that the performance of InstaPATCH 360 Pre-Terminated Fiber Solutions and LazrSPEED? Multimode fiber solutions far exceed the cable reach specified in IEEE Std. 802.3baTM-2010, “40 and 100 Gigabit Ethernet” standards.

SYSTIMAX InstaPATCH 360 Pre-Terminated Fiber Solutions utilize the standard Method B polarity scheme. Customers who have chosen the fiber solution have invested in high-performance and high-quality fiber solutions, but also have purchased peace of mind: their data center fiber cabling infrastructure is ready for 40/100GbE whenever and wherever they need it. The eventual upgrade can be a simple and painless process. Figure 3 shows samples of SYSTIMAX InstaPATCH 360 Pre-Terminated Fiber Solutions.

Solutions Designed to Maximize Return on Investment

The switching solutions from Cisco and cabling solutions from CommScope enable easy adoption of 10GbE today and seamless upgrades to 40/100GbE in the future.

The Cisco Catalyst 6500 E-Series chassis, 6900 series 10GbE and 40GbE modules, and Supervisor T2 module provide the easy upgrades. End users’ investment protection can be achieved by redeploying the common components. The common switching components may include a Catalyst 6500 E-Series chassis, a supervisor module Sup2T, and two power supplies. As illustrated in the example in Figure 4, end users can save 55 percent1 of capital expense on the common components for 40GbE short reach (SR), or 47 percent1 of expenses for 40GbE long reach (LR) when upgrading from 10GbE.

40GbE deployment in campus

40GbE-deployment-in-campus.jpg

Similarly, CommScope SYSTIMAX InstaPATCH 360 Pre-Terminated Fiber Solutions offer seamless migration from 10GbE to 40/100GbE with investment preservation. A typical preterminated multimode fiber cabling channel is composed of components such as apparatus, patch cord, patch panel or shelf, and Multi-Fiber Push On (MPO) trunk cable. Figure 5 illustrates the fiber cabling channel for 10, 40 and 10 Gigabit Ethernet link, respectively. It’s noticeable that the common cabling component among the three channels in Figure 5 is the pre-terminated fiber trunk cable. Figure 5 also provides a cabling infrastructure migration path from 10GbE today to 40 or 100GbE in the future.

Fiber cabling migrations from 10GbE to 40/100GbE

Fiber-cabling-migrations-from-10GbE-to-40-100GbE.png

Each physical Ethernet link has one cabling channel. The cabling cost of four 10GbE links (or channels), one 40GbE link, ten 10GbE links and one 100GbE. The cost is the result of adding the costs of all the cabling components and then dividing the sum by the number of Ethernet links (or cabling channels) for each corresponding speed.

The investment preservation example5 on pre-terminated fiber cabling

The-investment-preservation-example5-on-pre-terminated-fibe.png

With the reuse of the common cabling components—which are the SYSTIMAX InstaPATCH 360 Trunk Cable and 360G2-1U Modular Shelf in this example—end users can save 57 percent2 of the capital expense on multimode fiber cabling when migrating from today’s 10GbE to either 40GbE or 100GbE in the future.

The costs for 4x10G and 10x10G fiber cabling are denoted in Figure 6 for a rough reference to their corresponding counterparts of 40 and 100GbE, respectively. The fiber cabling cost for 1x40G is close to the one for 4x10G, while the 1x100G cost is 19 percent less than the one for 10x10G’s cost, in this example.

You may be wondering why the cost of the MPO cable increases when migrating from 4x10G to 1x40G and from 10x10G to 1x100G. This is because, as there are unused fibers, only a fraction of the trunk cost is allocated to the 10GbE scenarios; but for the 40G and 100G scenarios, the total trunk cost is allocated. In other words, only four out of six possible fiber circuits are lit in the 4x10G case, so only 4/6ths of the cost is applied. Similarly, only 10 out of 12 possible fiber circuits are lit in the 10x10G case so only 10/12ths of the cost is applied. Notice that the 57 percent investment preservation on fiber is not the only saving for end users.

When the distribution and core layer networks migrate to 40/100GbE, the apparatus and cords can be reused in other parts of the networks: for example, the access layer network for 10GbE or even Fibre Channel SAN networks. By doing so, end users may preserve more of their investment.

The ongoing adoption of 40/100GbE is already redefining the IT landscape. It represents the first step toward the next generation of high-bandwidth connectivity demanded by virtualized data centers and campuses. As 40/100GbE continues to unlock the full performance and economic potential of virtualized environments and more campus deployments, it will undoubtedly solidify its position as the new standard for best practice, speed and reliability.

Because it affords instant benefits as well as a streamlined upgrade path, forward-looking IT managers would be well advised to include 40/100GbE as a key part of any upgrade or new deployment plans, particularly those that include a need for campus-wide interconnectivity between data centers, and inside data centers and office buildings. In particular, Cisco Catalyst 6500 series switches with their 40GbE fiber module and CommScope SYSTIMAX InstaPATCH 360 pre-terminated, LazrSPEED and TeraSPEED? fiber solutions deliver the performance and reliability that position today’ s investment for rich returns in the future.

Cisco Catalyst 6807-XL Modular Switch Overview

January 19 2015 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

Cisco Catalyst 6800 Series Switch was introduced by Cisco for the next-generation campus. It is built on the rich DNA of the Cisco Catalyst 6500 Series Switch and provides high levels of scalability and performance. The Cisco 6800 Series provides unprecedented investment protection for migrations and upgrades from the Cisco Catalyst 6500-E Series Switch.

Evolution of Cisco Catalyst 6000 Series

Evolution-of-Cisco-Catalyst-6000-Series-.jpg

The Cisco 6800 Series Switch has been designed to meet the requirements of the next-generation enterprise network and to simplify the deployment of emerging  trends such as bring your own device (BYOD), mobility, pervasive video, collaboration, and resiliency and the resulting challenges of scale, security, and management, making it the ideal switch for all campus backbone deployments.

The Different Types of Ethernet Cables

December 31 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Networking

As the standard cables that are commonly used to connect a modem to a router, and to connect a router to a computer’s network interface card (NIC), Ethernet cables have many different categories, such as Category 3, Category 5, Category 5e, Category 6, Category 6a, and Category 7. These types of Ethernet Cables have been developed, and each category has different specifications as far as shielding from electromagnetic interference, data transmission speed, and the possible bandwidth frequency range required to achieve that speed. It may be hard to decide which one you need while looking at all the available options for Ethernet cabling. Actually, the category of cable is usually clearly printed on the cable’s sheath, so there can be no doubt as to the type of cable being used. But do you know about the main differences between these categories of Ethernet cable? So in the following part we will tell about the main features of each type of Ethernet Cable.

Category 3

Category 3 Ethernet cable, also known as Cat 3 or station wire, is one of the oldest forms of Ethernet cable still in use today. It is an unshielded twisted pair (UTP) cable that is capable of carrying 10 megabits per second (Mbps) of data or voice transmissions. Its maximum possible bandwidth is 16 MHz. Cat 3 cable reached the peak of its popularity in the early 1990s, as it was then the industry standard for computer networks. With the debut of the faster Category 5 cable, however, Cat 3 fell out of favor. It still can be seen in use in two-line telephone systems and older 10BASE-T Ethernet installations.

 

Category 5

Category 5 (Cat 5) Ethernet cable is the successor to the earlier Category 3. Like Cat 3, it is a UTP cable, but it is able to carry data at a higher transfer rate. Cat 5 cables introduced the 10/100Mbps speed to the Ethernet, which means that the cables can support either 10 Mbps or 100 Mbps speeds. A 100 Mbps speed is also known as Fast Ethernet, and Cat 5 cables were the first Fast Ethernet-capable cables to be introduced. They also can be used for telephone signals and video, in addition to Ethernet data. This category has been superseded by the newer Category 5e cables.

 

Category 5e

The Category 5e standard is an enhanced version of Cat 5 cable, which is optimized to reduce crosstalk, or the unwanted transmission of signals between data channels. This category works for 10/100 Mbps and 1000 Mbps (Gigabit) Ethernet, and it has become the most widely used category of Ethernet cable available on the market. While Cat 5 is common in existing installations, Cat 5e has completely replaced it in new installations. While both Cat 5 and Cat 5e cables contain four twisted pairs of wires, Cat 5 only utilizes two of these pairs for Fast Ethernet, while Cat 5e uses all four, enabling Gigabit Ethernet speeds. Bandwidth is also increased with Cat 5e cables, which can support a maximum bandwidth of 100 MHz. Cat 5e cables are backward compatible with Cat 5 cables, and can be used in any modern network installation.

 

Category 6

One of the major differences between Category 5e and the newer Category 6 is in transmission performance. While Cat 5e cables can handle Gigabit Ethernet speeds, Cat 6 cables are certified to handle Gigabit Ethernet with a bandwidth of up to 250 MHz. Cat 6 cables have several improvements, including better insulation and thinner wires, that provide a higher signal-to-noise ratio, and are better suited for environments in which there may be higher electromagnetic interference. Some Cat 6 cables are available in shielded twisted pair (STP) forms or UTP forms. However, for most applications, Cat 5e cable is adequate for gigabit Ethernet, and it is much less expensive than Cat 6 cable. Cat 6 cable is also backwards compatible with Cat 5 and 5e cables.

 

Category 6a

Category 6a cable, or augmented Category 6 cable, improves upon the basic Cat 6 cable by allowing 10,000 Mbps data transmission rates and effectively doubling the maximum bandwidth to 500 MHz. Category 6a cables are usually available in STP form, and, as a result, must have specialized connectors that ground the cable.

 

Category 7

Category 7 cable, also known as Class F, is a fully shielded cable that supports speeds of up to 10 Gbps (10,000 Mbps) and bandwidths of up to 600 Mhz. Cat 7 cables consist of a screened, shielded twisted pair (SSTP) of wires, and the layers of insulation and shielding contained within them are even more extensive than that of Cat 6 cables. Because of this shielding, they are thicker, more bulky, and more difficult to bend. Additionally, each of the shielding layers must be grounded, or else performance may be reduced to the point that there will be no improvement over Cat 6, and performance may be worse than Cat 5. For this reason, it’s very important to understand the type of connectors at the ends of a Cat 7 cable.

 The following table summarizes the most common types of Ethernet cables, including their maximum data transmission speeds and maximum bandwidths. 

 

Cable Type

Maximum Data Transmission Speed

Maximum Bandwidth

Category 3

10 Mbps

16 MHz

Category 5

250 MHz

Category 6 a

STP

10,000 Mbps

500 MHz

Category 7

SSTP

10,000 Mbps

600 MHz

With each successive category, there has been an increase in data transmission speed and bandwidth. To fully future-proof a network installation, the highest categories are recommended, but only if all of the other equipment on the network is capable of similar speeds. Otherwise, expensive cables will be only as fast as the slowest piece of hardware on the network.

 

Ethernet Cable Connectors

The ends of Ethernet cables that connect into a NIC, router, or other network device are known by several names. Modular connector, jack, or plug are the most commonly used terms. Shorter lengths of Ethernet cable are usually sold with the connectors already installed, but for custom installations requiring longer lengths, cable is often sold in bulk quantities, and connectors must be installed on the ends.

The most common type of connector for Ethernet installations is referred to as an "RJ-45" connector. It is officially known as an 8P8C connector, but this term is rarely used in the field, and the term "RJ-45" which was the telephone industry’s term for this connector’s wiring pattern, has become the customary colloquial name for the connector itself. Categories 3 through 6 all use the RJ-45 connector, but Cat 7 utilizes a specialized version of the RJ-45 called the GigaGate45 (GG45), which grounds the cable and allows for higher data transmission rates. There are two standard pin assignment configurations for RJ-45 connectors: T568A and T568B. The T568A standard is typically used in home applications, while T568B is used in business applications.

In every case, the specifications of the cable, such as its category, whether or not it is shielded, and whether or not it needs to be grounded, must match the specifications of the connector. For those who are confused or uncertain about crimping and installing connectors to cables manually, it is best to buy cables that already have connectors professionally installed.

 

Other Qualities of Ethernet Cables to Consider

There are a few important considerations that apply to all Ethernet cables. Data transmission rate and bandwidth both decrease with the increase of cable length, so the shorter the length, the better. For 10/100/1000BASE-T networks (those that have maximum speeds of 10, 100, or 1000 Mbps, including all the aforementioned cable types except for Categories 6a and 7), 100 meters is the maximum allowable cable length before the signal will degrade. For category 6a cables running at 10 Gbps speeds, 55 meters is the maximum allowable length, and even this length is only allowed in very good alien crosstalk conditions, or areas of low interference, such as when the cable is located far away from other cables that could cause interference.

There are some other terms regarding cable terminations that can complicate the shopping experience. Some cables are referred to as patch cables, while others are called crossover cables. Even though crossover and patch cables may look the same, they function differently. A patch cable is one that terminates with the same type of connector standard at both ends. The connectors terminating a patch cable can use the T568A or T568B standards, but both ends must be the same. A crossover cable, on the other hand, has one end that terminates in a T568A connector and another that terminates in a T568B connector. Patch cables are used to connect devices that are different from one another, such as a switch and a computer. Crossover cables are used to connect similar devices, as when a switch is connected to another switch, for example.

Another important distinction in Ethernet cables is whether they contain solid or stranded conductors.

Stranded-vs.-Solid-Core.gif

Solid conductor cables have one solid wire per conductor, while stranded conductor cables have several strands of wire (typically seven) wrapped around each other to form a single conductor. Each type has its own advantages and disadvantages. Solid conductor cables are best for fixed wires within the walls or structure of a building. The single conductors are sturdy enough to be punched down into wall jacks and patch panels, but not as easy to install into a typical RJ-45 connector. Stranded conductors, on the other hand, can fray when punched down into wall jacks, so they are better suited to be crimped into an RJ-45 connector. They are also more flexible and forgiving when bent at sharp angles, so they are better suited for patch cables and applications where the cable may be rolled up or otherwise moved around.

So when you’re setting up an Internet connection in your home or office, you’ll need to obtain the proper Ethernet cable to attach your computer to the modem. While connecting the cable is typically a simple task, finding the right one may be a bit more complex. While Ethernet cables may all look similar to one another, their specifications vary widely. It’s important to research what type of cable will work with your equipment, and you’ll also want to consider things like the price and quality of the cable, as well as the types and number of devices you’ll be connecting to your network. You could go for a cheap, industry standard solution such as Cat 5e cable or future-proof your network by opting for a Cat 7 cable. If you’re looking to connect one switch to another or bypass a router, maybe crossover cables are the solution, or maybe you need a lot of patch cables to connect more devices to your network. In any case, you’ll also want to ensure you’re purchasing the right length of Ethernet cable, and properly addressing any interference concerns. No matter what your networking needs are, eBay is sure to have the category, length, and condition of Ethernet cable to get you connected.

A Layer-3 Switch or A Router?

December 19 2014 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

Do you think that it’s not easy to select the very suitable network hardware for setting up your network, layer-3 switch or a router? What factors do you need to consider when you decide to buy network hardware? Generally, to choose a layer-3 switch or a router is not so complicated. Someone listed more differences between layer-3 switch and a router, which can help you make a smart decision. Let’s take a look.

In fact, a Layer 3 switch works much like a router. Why? Because it has the same IP routing table for lookups and it forms a broadcast domain. But pay attention, the “layer 3” feature makes the switch looks more like a “switch”.

The “switch” part of “Layer 3 switch” is there because:

  1. The layer 3 switch has 24+ Ethernet ports and no WAN interfaces.
  2. The layer 3 switch will act like a switch when it is connecting devices that are on the same network.
  3. The layer 3 switch is the same as a switch with the router’s IP routing intelligence built in.
  4. The switch works very quickly to switch or route the packets it is sent.

What-is-the-difference-between-a-Layer-3-switch-and-a-Route.jpg

Layer 3 Switch is really like a High-Speed Router without the WAN connectivity. When it comes to Layer 3 Switching, there are two kinds: hardware and software. With a hardware-based solution, the device is using an ASIC (A Dedicated Chip) to perform the function. With the software implementation, the device is using a computer processor and software to perform the function. Generally, Layer 3 Switches and High-End Routers route packets using Hardware (Asics) and General-Purpose Routers Use Software to Perform Routing Functions.

In General, A Layer-3 Switch (Routing Switch) Is Primarily A Switch (A Layer-2 Device) That Has Been Enhanced Or Taught Some Routing (Layer 3) Capabilities. A Router Is A Layer-3 Device That Simply Do Routing Only. In The Case Of A Switching Router, It Is Primarily A Router That Uses Switching Technology (High-Speed Asics) For Speed And Performance (As Well As Also Supporting Layer-2 Bridging Functions).

Why we need a Layer 3 switch:

  •  Network with a lot of broadcasts that needs better performance.
  • Subnets and/or VLANS that are currently connected Via a router.
  • Higher Performance VLANS.
  • Departments Need Their Own Broadcast Domains For Performance Or Security.
  • Considering Implementing VLANS.

 

Difference between a Layer-3 switch and a Router:

  •  Performance versus Cost— Layer 3 switches are much more cost effective than routers for delivering high-speed inter-VLAN routing. High performance routers are typically much more expensive than Layer 3 switches.
  • Port density— Layer 3 switches are enhanced Layer 2 switches and, hence, have the same high port densities that Layer 2 switches have. Routers on the other hand typically have a much lower port density.
  • Flexibility— Layer 3 switches allow you to mix and match Layer 2 and Layer 3 switching, meaning you can configure a Layer 3 switch to operate as a normal Layer 2 switch, or enable Layer 3 switching as required.
  • Layer 3 Switch is used to route traffic between Ethernet networks, without having to worry about the complexities of supporting WAN technologies such as Frame Relay or ATM. Routing over WAN networks, simply by plugging a traditional router that connects to the WAN networks into the LAN network.
  • The key difference between Layer 3 switches and routers lies in the hardware technology used to build the unit. The hardware inside a Layer 3 switch merges that of traditional switches and routers, replacing some of a router’s software logic with hardware to offer better performance in some situations.

If we sum up the main features of a layer-3 switch, we can get some key points as follows:

Layer 3 Switch is used Primarily for Inter-VLAN Routing. It don’t Have WAN Connectivity. It Has 24+ Ethernet Ports And No WAN Interfaces. The Layer 3 Switch will act like a switch when it is connecting devices that are on the same network. It works very quickly to switch or route the packets it is sent. The Layer-3 switch is the same as a switch with the router’s IP Routing Intelligence built in.
