SFP Module Cable Specifications
Table B-3 lists the cable specifications for the fiber-optic SFP module connections. Each port must
match the wave-length specifications on the other end of the cable, and for reliable communications, the
cable must not exceed the required cable length. Copper 1000BASE-T SFP transceivers use standard
four twisted-pair, Category 5 (or greater) cable at lengths up to 328 feet (100 meters).
Two Twisted-Pair Cable Pinouts
Figure B-6 and Figure B-7 show the schematics of two twisted-pair cables for connecting to 10BASE-T-
and 100BASE-TX-compatible devices.
