Optical coupler (Optical Coupler, abbreviated as OC in English) is also known as opto-isolator, or optocoupler for short. Optical couplers use light as a medium to transmit electrical signals. It has a good isolation effect on input and output electrical signals, so it is widely used in various circuits. At present, it has become one of the most diverse and versatile optoelectronic devices. The optical coupler generally consists of three parts: light emission, light reception and signal amplification. The input electrical signal drives the light-emitting diode (LED) to emit light of a certain wavelength, which is received by the photodetector to generate a photocurrent, and then output after further amplification. The optical isolator is a passive optical device that only allows one-way light to pass through. Its working principle is based on the non-reciprocity of Faraday rotation. The light reflected by the optical fiber echo can be well isolated by the optical isolator. Optical isolators mainly use the Faraday effect of magneto-optical crystals. The characteristics of the optical isolator are: low forward insertion loss, high reverse isolation, and high return loss. An optical isolator is a passive device that allows light to pass in one direction but prevents it from passing in the opposite direction. Its function is to limit the direction of light so that light can only be transmitted in one direction. The light reflected by the optical fiber echo can be reflected by the optical isolator. Good isolation, improve light wave transmission efficiency.
