Product Overview
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. The compact design and high performance make it ideal for telecommunications, fiber sensing, and dense wavelength-division multiplexing (DWDM) systems.
