The 3 Ports 1480nm High Power Polarization Insensitive Optical Circulator is a high-performance, non-reciprocal passive optical device designed to route light sequentially from Port 1 → Port 2 and Port 2 → Port 3, ensuring stable, unidirectional light transmission with minimal loss. Operating at 1480 nm, it is specifically optimized for EDFA pumping systems, Raman amplifiers, and high-power optical communication networks, where precise light control and excellent thermal stability are critical.
