ġ000BASE-EX SFP for long-reach single-mode fibers For details on this implementation, refer to. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable. The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. It can support up to 1km over laser-optimized 50 μm multimode fiber cable.ġ000BASE-LX/LH SFP for both multimode and single-mode fibers The 1000BASE-SX SFP, compatible with the IEEE 802.3z 1000BASE-SX standard, operates on legacy 50 μm multimode fiber links up to 550 m and on 62.5 μm Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m. Cisco 1000BASE-T SFP modules support 10/100/1000 auto negotiation and Auto MDI/MDIX. The 1000BASE-T SFP operates on standard Category 5 unshielded twisted-pair copper cabling of link lengths up to 100 m (328 ft). Supports Digital Optical Monitoring (DOM) capability.Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate”.Hot swappable to maximize uptime and simplify serviceability.
