My network is out of this world

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.
