Both switch engines are scheduled to ship in April.
In general, the Catalyst switches are designed for the campus backbone, the wiring closet, or a small office or retail network. Switch engines, which are the brains of the Catalyst, extend the usefulness of the hardware as application-driven network traffic rises.
The 6T raises speeds to 400 Gbps per slot on the Catalyst 6807-XL chassis. As a result, the supervisor engine can increase switch capacity to 6 Tbps and scale to 12 Tbps when in the Virtual Switching System configuration. The Supervisor Engine 6T is compatible with 10 Gb, 40 Gb and 100 Gb line cards, and has 8 x 10 GbE and 2 x 40 GbE uplinks to support high-performance applications.
The 8L-E has up to 560 Gbps of wired switching capacity and can handle independent packets simultaneously at a rate of 48 Gbps. The extension has four 10 GbE uplinks.
Cisco upgrades wireless, UCS platforms
With the latest switch engines, Cisco introduced the Catalyst 3650-Mini for companies with space-constrained locations. The hardware mirrors the 3650 family of switches in a 1RU form factor. It's available with 24 or 48 fixed PoE+ GbE ports.
For wireless networks, Cisco introduced 802.11ac Wave 2 access points under the Aironet and cloud-managed Meraki brands. The company also introduced stackable Meraki MS Switches that feature 16 or 32 1 Gbps ports, and hot-swappable power supplies and fans.
The Catalyst and wireless network upgrades reflect Cisco's two-prong product strategy of strengthening its on-premises and cloud-managed technology, which also includes security, said Rohit Mehra, an analyst at IDC. By focusing on both, Cisco is bolstering its core platforms for switching and routing, while also addressing the needs of the "midmarket, distributed enterprise that is developing a greater affinity for leveraging cloud for IT infrastructure."
For the data center, Cisco introduced the 6300 Series Fabric Interconnect for the company's Unified Computing System (UCS), which combines compute, storage and networking into a single platform. Cisco's fabric interconnects provide the management and communication backbone of the UCS B-Series Blade Servers, 5100 Series Blade Server Chassis and the C-Series Rack Servers.
The 6300 Series features two 1RU 40 GbE switches and a 40 GbE Fabric Extender. The products leverage the Virtual Interface Card 1300 series, which is designed to support up to 40 GbE networks. The card supports network overlay technologies, such as VXLAN.

Cisco’s QSFP 40G BiDi (bidirectional) transceiver, allows zero-cost fiber migration by reusing the current 10-Gbit/sec cabling for 40-Gbit/sec device connectivity. With duplex LC ports, it enables 100 meters of 40G transmission over OM3, 125 meters over OM4 fiber, and 150 meters over certain “OM4+” fibers.
Migrate to a 40-Gbps Data Center with Cisco QSSFP BiDi Technology? Cisco makes the case for its transceiver technology, taking direct aim at “the need for a major upgrade of the cabling infrastructure” when transitioning from 10G to 40G, “which can be too expensive or disruptive to allow data centers to quickly adopt and migrate to the 40-Gbit/sec technology.”
“Existing short-reach transceivers for 40-Gbit/sec connectivity in a QSFP form factor … use independent transmitter and receiver sections, each with 4 parallel fiber strands. For a duplex 40-Gbit/sec connection, 8 fiber strands are required.
Both QSFP SR4 and QSFP CRS4 use MPO 12-fiber connectors. As a result, 4 fiber strands in each connection are wasted.
“With existing QSFP transceivers, each direct connection between two devices requires an MPO-to-MPO 12-fiber cable. In the case of structured cabling with patch panels and fiber trunks, a 40-Gbit/sec connection needs MPO-to-MPO fibers between devices and patch panels, and 4 duplex multimode fibers in the fiber trunk.
“In most of today’s data center networks, the aggregation fiber infrastructure is built for 10Gbit/sec connectivity that either supports direct connections between devices over LC-to-LC multimode fiber or uses LC-to-LC fibers to attach devices to patch panels and provides one duplex multimode fiber in the fiber trunk for each 10-Gbit/sec connection.
“40-Gbit/sec connectivity using traditional 40-Gbit/sec transceivers cannot reuse directly connecting LC-to-LC fibers. It also requires four to six times greater fiber density in the fiber trunks to meet the requirements of a 40-Gbit/sec connection. These characteristics make it expensive for customers to migrate from 10-Gbit/sec connectivity to 40-Gbit/sec connectivity in their existing data centers.
“The Cisco QSFP BiDi transceiver addresses the challenges of fiber infrastructure by providing the capability to transmit full-duplex 40 traffic over one duplex multimode fiber cable with LC connectors. In other words, the Cisco QSFP BiDi transceiver allows 40-Gbit/sec connectivity to reuse the existing directly connecting 10-Gbit/sec fibers and the existing fiber trunk without the need to add any fibers.”
The technical paper details two deployment scenarios/case studies to emphasize the savings accomplished by eliminating the parallel-optic cabling infrastructure. The first scenario is a 288x40G setup with unstructured cabling. The second is a 384x40G setup with structured cabling. In this second scenario, the paper explains, “Cisco QSFP BiDi technology allows the existing cabling system—including the patch cables, patch panels with MTP/MPO LC modules, and fiber trunks—to be repurposed for 40-Gbit/sec connectivity. In contrast, QSFP SR4 transceivers require new patch cables and patch panels because the connector types differ and the size of the fiber trunk needs to be quadrupled.”
