In the optical fiber communication system, the task of the optical receiver is to recover the information carried by the optical carrier after optical fiber transmission with minimal additional noise and distortion. Therefore, the output characteristics of the optical receiver comprehensively reflect the entire optical fiber communication system performance.

After the optical signal transmitted by the optical transmitter is transmitted, not only the amplitude is attenuated, but the pulse waveform is also broadened. The function of the optical receiver is to detect the transmitted weak optical signal, and amplify, reshape, and regenerate the original transmission signal.

An optical receiver, sometimes called a fiber optic receiver, is a component in a fiber optic network. The role of the receiver is to translate pulses of light that are sent through optical fibers into electrical signals. Once the information is converted into electricity, the information can be read by an electronic device, such as a computer, that is attached to the network.

An optical receiver is an important component in a fiber optic network. In fiber optics, light is used to send information between electronic devices, such as two computers on a network. Cables, which are usually made of a highly reflective silica glass, are used to transmit pulses of light. The light bounces down the hollow tube of silica until it reaches the optical receiver at the other
