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, or 1000BASE-LX/LH SFP modules and a short link distance can
cause transceiver saturation, and 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).
