Fibre

​Fibre-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light[1] through an optical fibre. The light is a form of carrier wave that is modulated to carry information.[2] Fibre is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required.[3] This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.[4]

Optical fibre is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Researchers at Bell Labs have reached a record bandwidth–distance product of over 100 petabit × kilometers per second using fibre-optic communication.[5]
