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