What characterizes Multi-mode fiber?

Transmits single ray of light
Transmits multiple rays of light from LEDs
Used exclusively for deep-sea cables
Supports only digital signals

The correct answer is: Transmits multiple rays of light from LEDs

Multi-mode fiber is characterized by the ability to transmit multiple rays of light from LEDs. This is in contrast to single-mode fiber which only transmits a single ray of light. Option A is incorrect because it describes the characteristic of single-mode fiber. Option C is incorrect because multi-mode fiber is used in a variety of applications, not just for deep-sea cables. Option D is incorrect because multi-mode fiber can support both digital and analog signals.
