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
can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP module with 62.5-micron diameter
MMF, you must also install a mode-conditioning patch cord between the SFP module and the MMF cable on both the sending and receiving ends
of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m).
2. 1000BASE-ZX SFP modules can reach up to 100 km by using dispersion-shifted SMF or low-attenuation SMF; the distance depends on the fiber
quality, the number of splices, and the connectors.
