What is fiber-optic communication?
It is a way of transmitting data from one place to another through an optic fiber. Fibers are used instead of metal wires because signals along them would be lost. Lights send pulses through the optic fiber. It revolutionized the telecommunication industry.
Lights form an electromagnetic carrier wave. The advantage over copper wiring is the immunity to electromagnetic interferences, and low attenuation loss over long distances. A single optical fiber can carry 3,000,000 full-duplex voice calls. single fiber can carry much more data than electrical cables such as standard category 5 Ethernet cabling. The two main types of optical fiber is multi-mode optical fibers and single-mode optical fibers.
