Polarization Maintaining Optical Circulator
The PM optical circulator is a 3 port fiber optic device build with PM panda fiber, it transmits 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 pigtails, 900um pigtails or 3mm cable.
