Optic fiber is widely used in telecommunication networks of high data capacity for high-quality long-distance data transmission.
Due to its broadband nature optic fiber allows to transmit large data flows (some thousands of channels), for all that it has small overall dimensions and weight (10 times smaller than electric cable).
Owing to small signal loss optic fiber can be used for long data transmission segments (30…70 and 100 km). It has protection against external effects, transient noise and reliable safety measures (absence of arcing and short-circuit).
