3 Ports 1550nm High Power Polarization Maintaining Optical Circulator

3 Ports 1550nm High Power Polarization Maintaining Optical Circulator

The 3 Ports 1550nm High Power Polarization Maintaining Optical Circulator is a precision-engineered, non-reciprocal passive optical device designed to route light sequentially from Port 1 → Port 2 and Port 2 → Port 3, while maintaining the input polarization state with high stability. Operating at the 1550 nm wavelength, this device offers low insertion loss, high isolation, high return loss, and an excellent polarization extinction ratio (PER), ensuring reliable and efficient performance in high-power polarization-sensitive systems.

Constructed with PLMA-GDF-10/125-M fiber, the circulator maintains accurate polarization alignment, with the slow axis aligned to the key by default, guaranteeing stable optical transmission under both continuous-wave (CW) and pulsed operation. It features high optical power handling capability and outstanding thermal stability, making it ideal for DWDM systems, EDFA and Raman amplifiers, fiber lasers, interferometers, and coherent communication setups.

The device’s compact, rugged, and thermally stable design ensures superior long-term reliability, even under high optical power conditions, making it an essential component in advanced fiber-optic and laser systems.
