The 3 ports Polarization Maintaining optical circulator is a 3 ports micro-optic device built with PM fiber. The PM Circulator transmits a signal from port1 to port2 and transmits another signal from port2 to port3 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.
Application:
Fiber lasers
Fiberoptic Sensors
Optical Amplifier
CATV Systems
Dispersion Compensation
Features:
High extinction ratio
High isolation
Low Insertion Loss
Excellent stability and reliability
