In this chapter, we will first introduce the historical use of optical communication, followed by the description of emerging modern optical-fiber communication. To understand the significant progress of optical communication in the late 20th century, the fundamentals of light need to be understood. ...

fiber optic communication system in general Message Origin. Quite ofen it is a transducer that converts a nonelectrical message into an electrical signal. Such as MIC to converts sound waves into currents. Something like you write your idea on to a paper by letters. Mudulator. It has two ...
The major function of a photodetector is to convert an optical information signal back into an electrical signal (photocurrent光电流). The photodetector in todays fiber-optic communication 27、 system is a semiconductor photodiode (PD光电二极管) photodetector + electrical circuitry =receiverPower-supply...
