3 Ports Polarization Maintaining Optical Circulator
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.
*Low ion loss
*High extinction ratio
*High isolation
*Excellent stability and reliability
Applications
* Fiber lasers
* Fiber Sensors
* Optical Communications
* Polarization Mode Dispersion Compensator
