Description:
Fiber Optic 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.
