Product description
3 Port 4 Port Polarization Maintaining Optical Circulator Pm Fiber Circulator
Polarization Maintaining optical circulator is a micro-optic device built.
3 Port PM Circulator transmits a signal from port1 to port2 and transmits another signal from port2 to port3.
4 ports Polarization Maintaining optical circulator transmits the incoming signal from port1 to port2, from port2 to port3, from
port3 to port4 while maintaining the polarization of the signal.
It is characterized with low insertion loss, high isolation, high return loss, high extinction ratio and excellent environmental
stability and reliability. It is widely used in fiber amplifier systems, fiber lasers and optical fiber sensors.
