Description
1625nm High Power PM 3-port Optical Circulator
1625nm High Power 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, Fiber Optic Sensor and Coherent Detecting field. The Optical Power can be up to 20W CW upon request.
