Product information "3 Ports PMCIR Fiber Optic Circulators"
Polarization Maintaining; 1064, 1310, 1550 nm; 4 Ports; Insertion Loss ≤1.0 to ≤4.0 dB; Fiber Type PM
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.
