Optical isolator


Number of views:



An optical isolator is a passive optical device that only allows light to pass through in one direction. Its working principle is based on the non-reciprocity of Faraday rotation. The light reflected by the fiber optic 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 and prevents it from passing in the opposite direction. Its function is to limit the direction of light so that the light can only be transmitted in one direction. Very good isolation, improve light transmission efficiency
