SFP Module Cable Specifications

Table B-3lists the cable specifications for 100BASE-FX, 1000BASE-SX, 1000BASE-LX, 1000BASE-ZX, and CWDM fiber-optic SFP module connections. Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed the stipulated cable length. Copper 1000BASE-T SFP transceivers use standard four twisted-pair, Category 5 cable at lengths up to 328 feet (100 meters).
