Key Feactures and Benefits for WS-X6904-40G-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, as listed in Table 2.
