Answer / Munender Singh
Optical Communication refers to the transmission of information using light signals. It employs optical fibers as the primary medium for data transport. The main advantages of optical communication include:
1. High bandwidth: Optical fibers can transmit vast amounts of data compared to traditional copper wires.
2. Low signal attenuation: Light signals travel longer distances with minimal loss in comparison to electrical signals.
3. Immune to electromagnetic interference: Optical communication is less susceptible to external interference from electrical devices and environmental factors.
4. Security: Light signals can be easily encrypted, making optical communication more secure than traditional wired or wireless communication.
