Product information "4 Ports PMCIR Fiber Optic Circulators"
Polarization Maintaining; Fiber Type PM Fiber; 1064, 1310, 1550 nm; 3 Ports; Insertion Loss ≤0.8 to ≤3.5 dB
The 4 ports Polarization Maintaining optical circulator is a 4 ports micro-optic device built with PM fiber. The PM 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.
