Cisco WS-X6908-10G-2T= network switch module

Catalyst 6900 Series 8-Port 10 Gigabit Ethernet Fiber Module with DFC4, Spare The Cisco® Catalyst® 6500 Series Switches offer a variety of 10 Gigabit Ethernet modules to serve different needs in the campus and data center for enterprise, commercial, and service provider customers. The Cisco Catalyst 6900 Series 8-port 10 Gigabit Ethernet Fiber Module is the first 10 Gigabit Ethernet Module for the Cisco Catalyst 6500 Series Switch that supports Cisco TrustSec and Layer 2 encryption in hardware to enable IEEE 802.1ae (MACSec) encryption for Role-Based Access Control (RBACL) functionality. The module has two 40 Gbps connections (for a total of 80 Gbps) to the 2Tbps switch fabric of the Supervisor Engine 2T and therefore is able to deliver 10 Gigabit performance on all 8 ports for larger than 128 bytes size packets with no oversubscription. The new Cisco Catalyst 6900 Series 8-port 10 Gigabit Ethernet Fiber module supports Virtual Switch Link (VSL) on all 8 ports. The Cisco Catalyst 6900 Series 8-port 10 Gigabit Ethernet Fiber Module supports pluggable X2 optics, providing operational distances of up to 80 km over single-mode fiber and 300m over multimode fiber allowing for deployment in various types of networking environments. The Cisco Catalyst 6900 Series 8-Port 10 Gigabit Ethernet Fiber Module is only compatible with the new Cisco Catalyst 6500 Supervisor Engine 2T (VS-S2T-10G or VS-S2T-10G-XL), enabling the system to deliver three times the performance and four times the scalability for Cisco Catalyst 6500 Series Switches in comparison to the previous generation.
