The WS-X4908-10GE is the Cisco Catalyst 4900M 8-port 10 Gigabit Ethernet half card with X2 interfaces, running at 2:1. A 4900M base system, a 320-Gbps switch, takes up to two half cards in any combination.
This is the one 4900M half card that works with the Cisco TwinGig Converter Module (CVR-X2-SFP=). The converter turns a single X2 interface into two Gigabit Ethernet SFP slots, and the SFPs for those slots include GLC-T, GLC-SX-MM, GLC-LH-SM, GLC-BX-D, GLC-BX-U and GLC-ZX-SM.
The half card weighs 2.5 lb (1.1 kg) and the spare number is WS-X4908-10GE=. Cards can be inserted and removed online, and the base system can mix X2 and RJ-45 half cards. The TwinGig route lets a site deploy Gigabit Ethernet now and migrate to 10 Gigabit Ethernet later.
Copper users can look at the WS-X4908-10G-RJ45 8-port 10GBASE-T half card, which has RJ-45 ports instead of X2 sockets. Other 4900M and 4500 parts are in Cisco switches.
