The PM Optical Circulator is a non-reciprocal device that minimizes back reflection and back scattering in the opposite direction while maintaining polarization and rerouting light at 1310/1550 nm from port to port in just one direction. It has a low insertion loss, a high extinction ratio, high isolation, a small packaging, and great stability due to its innovative microoptic design.
