Description
1760nm PM 3-port Optical Circulator
1760nm PM 3-port Optical Circulator is a fiber passive component built with faraday crystal, which can change signal light transmission path, the signal can be delivered from Port 1 to Port 2, the other signal light from Port 2 to Port 3, the high isolation can block the back reflection light. It’s widely used in Laser System, Fiber Optic Sensor and Coherent Detecting field. High Power version is also available upon request.
