What is PM optical circulator

PM optical circulator can be used in fiber lasers, add-drop multiplexers, bidirectional pumping systems, dispersion compensation devices, fiber optic sensing, scientific research and other fields.

The 1310/1550 PM Optical Circulator is a non-reciprocal device that maintains polarization while redirecting light at 1310/1550 nm from port-to-port in only one direction while minimizing back reflection and back scattering in the reverse direction.
