Q: Why optical fiber is more useful tool for the communication process?

• Optical fibers transmit information over large distances via light, with minimum loss of energy.
• They have high bandwidth over large distances.
• These optical fibers can easily be installed in houses or in offices as they occupy less space because of their small diameter.
• Fiber optic cables are immune to Electromagnetic interference and produce no interference while operating.
• There is no fire hazard while using optical fibers because light is transmitted through them.
• They are cheaper than ordinary copper wires.
