*Mode-conditioning patch is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFPs, and a short link distance (10s of meters) can
cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the LX/LH 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 300 m (984 ft).

** 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.
