Polarization Maintaining Optical Circulator
The PM optical circulator is a 3 port fiber optic device built with PM panda fiber. It transmits a signal from port1 to port 2 and another signal from port 2 to port 3 while maintaining the polarization. The PM Circulator features low insertion loss, high isolation between ports, low PDL, high extinction ratio and high reliability and stability. The device can be built with 250um bare fiber, 900um jacket or a 3mm cable jacket.
