  • 6800 Series 16-Port 10 Gigabit Ethernet Fiber Module

    The 6800 series 16-port 10 Gigabit Ethernet fiber module is suitable for deployment in access and aggregation network in Campus and Data Center:

    • WS-X6816-10G-2T: 16-port 10 Gigabit Ethernet Fiber Module with DFC4 (Figure 1) and

    • WS-X6816-10G-2TXL: 16-port 10 Gigabit Ethernet Fiber Module DFC4XL (Figure 1)

    • Backplane connection: Connects to the switch fabric using dual full-duplex 20 Gbps switch fabric channels (40 Gbps total).

    • Chassis/slot support: Can occupy any slot in Cisco Catalyst 6503E, 6504E, 6506E, 6509E, and 6509-V-E. Can occupy slots 1-6 and 9-13 in a Cisco Catalyst 6513-E.

    • Supervisor engine: Compatible with Supervisor Engine 2T and Supervisor Engine 2TXL

    • Distributed forwarding and performance: Comes equipped with DFC4 or DFC4XL daughter cards, delivering optimal performance up to a sustained 60 Mpps for L2, IPv4 and MPLS forwarding and 30 Mpps for IPv6 forwarding.

    The 6800 Series 16-port 10 Gigabit Ethernet Fiber module (Figure 1) provides up to 176 10 Gigabit Ethernet Fiber ports in a single Cisco Catalyst 6513-E Switch chassis, 352 10 Gigabit Ethernet Fiber ports in a Cisco Catalyst 6500 Virtual Switching System (VSS) 2T.
