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