3 Ports 1550nm High Power Polarization Insensitive Optical Circulator

3 Ports 1550nm High Power Polarization Insensitive Optical Circulator

The 3 Ports 1550nm High Power Polarization Insensitive Optical Circulator is a high-performance, non-reciprocal passive optical device designed to direct light sequentially from Port 1 → Port 2 and Port 2 → Port 3, ensuring precise, unidirectional light propagation with minimal insertion loss. Operating at 1550 nm, it is optimized for C-band optical communication systems, high-power DWDM networks, EDFA and Raman amplifiers, and various fiber-optic testing and sensing applications.

Featuring a polarization-insensitive design, this circulator maintains stable optical performance regardless of input polarization. It delivers low insertion loss, high isolation, high return loss, and excellent power handling capability for both CW and pulsed laser operations. Built with LMA-GDF-10/125-M fiber, it ensures low back reflection and high stability under high optical power levels.

The device’s compact, thermally stable, and rugged construction provides outstanding reliability and long-term performance, making it suitable for integration into optical amplifier modules, laser systems, and research equipment where high-power and low-loss operation are essential.
