A mode-conditioning patch cord (part number CAB-GELX-625 or equivalent) is required. If you use an
ordinary patch cord with MMF, 1000BASE-LX SFPs, 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 long-reach
SFP with 62.5-micron-diameter MMF, you must install a mode-conditioning patch cord between the SFP 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 (300m).

1000BASE-ZX SFP can reach up to 100 km by using dispersion-shifted SMF or low attenuation SMF; the
distance depends on fiber quality, number of splices, and connectors.
