3 Ports 1064nm Singlemode Polarization Insensitive Optical Circulator

3 Ports 1064nm Singlemode Polarization Insensitive Optical Circulator

The 3 Ports 1064nm Singlemode Polarization Insensitive Optical Circulator is a high-performance, non-reciprocal passive device designed to route light sequentially from Port 1 → Port 2 and Port 2 → Port 3 with minimal insertion loss and excellent isolation. Operating at the 1064 nm wavelength, this circulator is optimized for high-power fiber laser systems, optical amplifiers, interferometers, and precision measurement applications, ensuring stable and efficient light transmission in singlemode fiber networks.

Engineered with a polarization-insensitive design, the device maintains consistent performance regardless of the input polarization state. Its low insertion loss, high return loss, and robust power-handling capability make it well-suited for demanding environments such as industrial laser systems and R&D laboratories. The compact and durable package ensures long-term reliability and easy system integration.

Specifications

Note: Test environment: 25°C. Data shown exclude connectors. Adding connectors will increase insertion loss by 0.3dB and reduce return loss by 5dB.

Application Diagrams

Circulator can be used to send optical signals through a single fiber in two directions.
As the picture shows: A Circulator is located at both ends of the fiber. Each Circulator functions to add a signal in one direction while removing the signal in the other.
