Note 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.

1. Modal bandwidth applies only to multimode fiber.
2. 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.
3. A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
4. 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 feet (300 m).
