Description
850±50nm Broadband 3-port PM Optical Circulator
850±50nm Broadband 3-port PM Optical Circulator is a fiber passive component built with TGG 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 OCT System, Fiber Optic Sensor and Coherent Detecting System field. High Power type is also available upon request.
