3 Ports 1480nm High Power Polarization Maintaining Optical Circulator

3 Ports 1480nm High Power Polarization Maintaining Optical Circulator

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.

Constructed with PLMA-GDF-10/125-M fiber, the device ensures accurate polarization alignment with the slow axis aligned to the key (default). It delivers low insertion loss, high isolation, high return loss, and an excellent polarization extinction ratio (PER), guaranteeing stable and efficient optical transmission under both continuous-wave (CW) and pulsed operation.

The circulator features robust mechanical construction, high-damage-threshold optical coatings, and outstanding thermal stability, ensuring reliable performance even under elevated optical power. Its compact design makes it ideal for integration into optical amplifier systems, fiber laser setups, interferometers, and precision sensing applications.
