Cisco WS-X6908-10G-2TXL card is an ideal solution for your business network or Data center. Bay Networks stock Cisco Catalyst 6900 Series 8-port 10 Gigabit Ethernet Fiber Module. The first 10 Gigabit Ethernet module 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 to the 2 Tbps switch fabric of the supervisor engine 2 T and therefore is able to deliver 10 Gigabit performance on all 8 ports for larger than 128 bytes size packets with no oversubscription. The 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 300 m 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 designed for deployment in the distribution and core of the campus and data center for traffic aggregation in a network requiring security, manageability, virtualization, application performance, and video. With its large 256 MB packet buffers per port, no oversubscription, and distributed forwarding with high scalability.
