Optical Fiber Amplifiers

Basically what the optical fiber amplifiers to solve , is the traditional distance problem as in every long-distance telecommunications system as a transatlantic link. To travel as optical signals through the fiber , the signals are weaker in power. The further you get , the weaker become the signal until they are too weak to be detected is safe.

Optical fiber communication systems solve this problem by the fiber amplifier on the way . An amplifier or amplifier at a point where the signal has become weak , to increase the strength of the signal so that they can be transmitted through a different length of the glass fiber cable is introduced into the system. Many amplifiers or repeaters are placed in order to keep the signal is strong along the entire fiber link .

What are the differences between a repeater and an optical fiber amplifier?

Traditional electronic amplifier for the optical signal amplification was used. A repeater is an opto - electro- optical device. Converts weak optical signal into said electronic signal , said electronic signal , and then purified converts the electronic signal back to optical signal by an optical transmitter . Optical transmitter emits much stronger force than to the incoming optical signal and amplifies it so .Read More
