Product Description
Industrial Temperature 3-Port Fiber Circulator
HJY's Optical Circulator is a non-reciprocal passive device that directs light signals sequentially between ports (Port 1→2, Port 2→3, Port 3→1). Utilizing Faraday rotation and birefringent crystals, it enables bidirectional optical routing with minimal loss, featuring low insertion loss, high isolation, and compact design for telecommunications, fiber sensing, and DWDM systems.
