Fiber Optical Isolator: Single/Dual Stage Optical Isolator

Item No.: Y-FO-OI-004
Optical isolator is also known as optoisolators, optocouplers and photocouplers, it can transmit light in a certain direction while blocking light in the opposite direction.
Description Parameters Company Profile Related Product
An optical isolator is a passive magneto-optic device that only allows light to travel in one direction. Isolators are used to protect a source
from back reflections or signals that may occur after the isolator. Back reflections can damage a laser source or cause it to mode hop,
amplitude modulate, or frequency shift. In high-power applications, back reflections can cause instabilities and power spikes.Optical isolators
are also known as optoisolators, optocouplers and photocouplers.
