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).

2. A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance can
cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter MMF, you must
also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends of the link. The
mode-conditioning patch cord is required for link distances greater than 984 feet (300 m).
