The 3 Ports 1480nm High Power Polarization Maintaining Optical Circulator is a high-performance, non-reciprocal passive optical device designed to transmit light sequentially from Port 1 → Port 2 and Port 2 → Port 3, while preserving the polarization state of the input signal. Operating at 1480 nm, this circulator is specifically engineered for EDFA pumping systems, Raman amplifiers, and high-power optical networks, where polarization stability and power handling are critical for optimal performance.
