
A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.

A mode-conditioning patch cord is required when using 1000BASE-LX/LH SFP modules, MMF, and a short link
distance . Using an ordinary patch cord 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 feet (300 m).

1000BASE-ZX SFP modules can send data up to 62 miles (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.

When the fiber-optic cable span is less than 15.43 miles (25 km), insert a 5-decibel (dB) or 10-dB inline optical
attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX SFP module.
