PM Optical Circulator

Firsol PM optical circulators are passive, nonreciprocal 3-port components engineered to route light from Port 1 to Port 2 and from Port 2 to Port 3 while maintaining linear polarization launched along the specified PM fiber axis. Low insertion loss, high isolation, and high extinction ratio make them suitable for fiber lasers and amplifiers, interferometers, fiber-optic gyroscopes, coherent systems, FBG sensing, and other polarization-sensitive applications. Models are available at 1064, 1310, 1480, and 1550 nm and across the C+L band. Slow-axis operation is standard, with fast-axis and both-axis options available. Fiber type, power handling, pigtail length, connector, and package can be customized for specific system requirements.
