SFP Module Cables

Each port must match the wave-length specifications on each end of the cable, and for reliable communications, the cable must not exceed the allowable length. Copper 1000BASE-T SFP transceivers use standard four twisted-pair, Category 5 (or greater) cable at lengths up to 328 feet (100 meters).

Note The maximum operating temperature of the switch varies depending on the type of SFP module that you use. See Table 1-2 on page 1-5for information on the supported temperature ranges.
