Table 4 provides cabling specifications for the GBICs that you install in the Gigabit Ethernet port.
Note that all GBIC ports have SC-type connectors, and the minimum cable distance for all GBICs
listed (multimode fiber [MMF] and SMF) is 6.5 feet (2 m).

MMF only.
Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. Using an ordinary patch cord with MMF,
1000BaseLX/LH GBICs, and a short link distance (10's of meters) can cause transceiver saturation resulting in an elevated bit error
rate (BER).
In addition, when using 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).
