Description
1450nm PM 4-port Optical Circulator
1450nm PM 4-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, Port 2 to Port 3, Port 3 to Port 4, the high isolation can block the back reflection light. It’s widely used in Fiber Amplifier System, Fiber Optic Sensor and Testing System field. High Power version is also available upon request.
