3 Ports 1310nm High Power Polarization Maintaining Optical Circulator

3 Ports 1310nm High Power Polarization Maintaining Optical Circulator

The 3 Ports 1310nm High Power Polarization Maintaining Optical Circulator is a precision-engineered, non-reciprocal passive optical device designed to transmit light sequentially from Port 1 → Port 2 and Port 2 → Port 3, while maintaining the input polarization state with excellent stability. Operating at 1310 nm, this device ensures low insertion loss, high isolation, high return loss, and a superior polarization extinction ratio (PER), delivering reliable performance in high-power polarization-sensitive optical systems.

Constructed with PLMA-GDF-10/125-M fiber, the circulator ensures accurate polarization alignment, with the slow axis aligned to the key (default). It offers excellent stability under both continuous-wave (CW) and pulsed operation, supporting power levels up to 100 W CW and 20 kW @ ns pulse. The device’s robust and thermally stable design guarantees long-term reliability even under high optical power conditions.

This circulator is ideal for use in optical amplifier systems, interferometers, fiber-optic sensing, coherent communication, and laser applications, where polarization control and high-power handling are essential.
