Compact and High-Performance 1310nm or 1550nm 3 Port Optical Circulator In Optical Communication
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.
