What is the difference between fiber optic communication and wired telecommunication

One, the principle of different

1, fiber-optic communication: light waves as the information carrier, optical fiber as a transmission medium of a communication mode.

2, wired communication: the use of linear, tubular materials as a channel transmission medium or medium interface for communication.

Second, different characteristics

1, fiber optic communications: signal interference, good confidentiality; electromagnetic interference, good transmission quality, electrical communications can not solve the problem of electromagnetic interference, only fiber optic communications are not subject to a variety of electromagnetic interference; optical fiber size is small, lightweight, easy to lay and transport.

2, wired electric communication: stable communication quality, free from interference and so on. But it also has obvious shortcomings, is the high cost, maintenance workload, vulnerable to natural damage and artillery attacks.

Three, different functions

1, fiber optic communication: fiber optic technology in the elevator on the application of fiber optic technology greatly improves the response speed of the entire control system, so that the elevator system of parallel group control performance has been significantly improved. The fiber optic communication device used on the elevator is mainly composed of light source, photoelectric receiver and optical fiber.

2, wired electrical communication: can transmit sound, text, data and images.
