Which of these light sources is commonly associated with multimode fiber?
A) Red laser
B) Incandescent
C) Light-emitting diode
D) Green laser
E) Aurora Borealis
The answer: C) Light-emitting diode
Multimode fiber is used for relatively short distances, so a high-powered (and expensive) light source is not necessary. For many of these installations, an LED light is used to transmit information from one side of the fiber to the other.
