Description:
Optical circulator is a special fiber optic device that is capable of separating optical power traveling in opposite
directions in one optical fiber.
It can be used to achieve bi-directional transmission over a single fiber. Because of its high isolation between the
input and reflected optical power and its low insertion loss, optical circulator is widely used in advanced communication
systems and fiber-optical sensor systems.
