Company Profile

ROHS 1550nm Fiber Optical Circulator 3 Port Polarization Maintaining

Polarization Maintaining optical circulator is a micro-optic device built with PM fiber. 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.
