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.
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.
