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
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
