ABSTRACT
Optical receivers are an essential part of a communication system. An optical receiver converts an optical signal, transmitted through an optical fibre cable into an electrical signal suitable for a receiving device installed at the other end of the communication system. The conversion process in the receiver is performed by two essential parts: a detector and an electronic signal processor. The detector converts the optical signal into an electrical signal. The electronic signal processor converts the raw detector signal into a form decipherable by the receiving device, such as a telephone, camera, or scanner.
