Оптоволокно - Optical fiber презентация

long distances.With low-loss optical fiber link can transmit the signal over distances of tens of kilometers without amplifiers.
Optical fiber - yarn of optically transparent material (glass, plastic) used to transfer light inside by total internal reflection.

strength element (CSE) - steel wire or fiberglass rod inside the dielectric optical cable, twisted around which the optical modules. Serves to reinforce the structure of the cable, under the influence of various loads, including wind loads and tension loads

Unauthorized connections to the cable is almost impossible
Speed ​​data transmission via fiber optic system is from 1 to 10Gbit / s.
Allows you to transmit information over long distances.
Fire and explosion safety
Small size and weight
High reliability optical media: optical fibers do not oxidize, do not get wet, are not subject to the weak electromagnetic interference.

strong bending of the cable may break fibers or turbidity due to the appearance of microcracks.
Complexity compounds in case of breakage.
Complex manufacturing process of both the fiber and the fiber optic link components.
