Question:
Which of the following Light source is popularly used in optical communication?
Which of the following Light source is popularly used in optical communication?
Show Hint
Infrared light is most suitable for optical communications due to low attenuation losses. Remember the spectrum of the electromagnetic wave and it's characteristics.
Updated On: June 02, 2025
- Visible light
- Ultraviolet
- Infrared
- Radio frequency
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Infrared light sources are most popularly used in optical communication systems because they have high frequencies, they are easily generated, and are attenuated less than other sources in optical fibers, making them ideal for transmitting signals over longer distances.
