* Mode-conditioning patch is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP/GBICs,
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/GBIC 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.
For more information refer to Cisco GBICs and SFP datasheets.
