Question
Which of the following is used as a receiver in optical fiber communication?
- Photodiode
- LED
- LDR
- IR Diode
- LASER
Solution
In optical fiber communication, a Photodiode is used as a receiver.
Here's a step-by-step explanation:
-
In optical fiber communication, information is transmitted by sending light down a fiber optic cable.
-
This light is typically produced by a laser or a light-emitting diode (LED).
-
The light travels down the fiber optic cable and is received at the other end by a photodiode.
-
The photodiode works by converting the light signal back into an electrical signal.
-
This electrical signal can then be processed and interpreted to extract the original information.
So, while LEDs and lasers are used as transmitters in optical fiber communication, photodiodes are used as receivers.
