1. Modal bandwidth applies only to multimode fiber.
2. A mode-field diameter/cladding diameter = 9 micrometers/125 micrometers.
3. Requires a mode-conditioning patch cord. 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. Link distances
greater than 984 feet (300 m) require the mode-conditioning patch cord.
4. 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), you should insert a 5-decibel (dB) or
Note
10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the
1000BASE-ZX SFP module at each end of the link.
