3 Port Polarization Maintaining PM Optical Circulator 1550nm Low Insertion Loss High Isolation

PM Circulator is an optical device used to achieve unidirectional transmission of optical signals in fiber optic systems while maintaining the polarization state of the optical signal. PM Circulator is based on magneto-optical effect and waveguide technology, and usually consists of a polarization-maintaining optical fiber and magneto-optical materials. It has three ports called input port, output port and reflection port. The input optical signal enters the PM Circulator through the input port, and then is transmitted and coupled between different ports.
