Optical circulator

Product Model

Optical circulator

Product Description

Fiber Optic Circulator is a unidirectional device that directs optical signals from one port to another, and transmits only one way at a time. Although the optical signal can be redirected as required, the optical signal must pass through each port in sequence .

In addition, fiber optic circulators can be used to achieve bidirectional transmission on one fiber. Because of

its low insertion loss and high isolation of input and reflected optical power, fiber optic circulators are widely

used in advanced communications systems and fiber optic sensor applications
