Product Details
Polarization Maintaining optical circulator is a micro-optic device
built with PM fiber. 3 Port PM Circulator transmits a signal from
port1 to port2 and transmits another signal from port2 to port3. 4
ports Polarization Maintaining optical 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.
