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