Polarization Maintaining Isolator
|
(PMI Series)
The Polarization Maintaining Isolator is characterized with low insertion loss, high isolation, high
return loss,high extinction ratio and excellent environmental stability and reliability. It is ideal for
polarization maintaining Fiber Amplifer, Fiber Laser, high speed communication systems and
instrumentation applications.
