1. Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. If you use an ordinary patch cord with MMF,
1000BASE-LX/LH GBICs, and a short link distance (tens of meters), this can cause transceiver saturation, resulting in an
elevated bit error rate (BER). In addition, when you use the LX/LH GBIC with 62.5-micron diameter MMF, you must install
a mode-conditioning patch cord between the GBIC 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).
