Product Description
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. This compact device features low insertion loss, high isolation, and excellent stability, making it ideal for telecommunications, fiber sensing, and dense wavelength-division multiplexing (DWDM) systems.
