HJY's Optical Circulator is a non-reciprocal passive device that
directs light signals sequentially between ports (e.g., Port 1→2,
Port 2→3, Port 3→1). It utilizes Faraday rotation and birefringent
crystals to enable bidirectional optical routing with minimal loss.
Key features include low insertion loss, high isolation, and
compact design, making it ideal for telecommunications, fiber
sensing, and dense wavelength-division multiplexing (DWDM) systems.
