The WS-X4448-GB-SFP has 48 SFP slots. The slots are 1000BASE-X, and the SFPs are optional. Each slot takes the optic type the link needs.
Different 1000BASE-X SFP optics can sit side by side on one card. IEEE 802.3x flow control applies, and the wire-rate ratio is 8-to-1. Typical uses are server farms, switch-to-switch links and point-to-point Gigabit Ethernet fiber to the home.
Maximum rated power is 65 W and rated MTBF is 290,732 hours. A 4503-E holds 48 to 96 ports with it, a 4506-E, 4507R-E or 4507R+E holds 48 to 240, and a 4510R-E or 4510R+E holds 48 to 384. It is a 6 Gbps per slot classic card, and WS-X4448-GB-SFP= is the spare number.
A 48-port copper alternative is the WS-X4548-GB-RJ45V 48-port PoE module. Find more Catalyst 4500 cards and modules in Cisco switches.
