Multimode graded index fibers use incoherent source only.

Multimode graded index fibers use incoherent source only. Correct Answer False

Multimode graded index fibers are used for short haul and medium to high bandwidth applications. Small haul applications require LEDs and low accuracy lasers. Thus either incoherent or incoherent sources like LED’s or injection laser diode are used.
