Polarization Maintaining Isolator(PMISO)

The Polarization Maintaining Isolator is a micro-optic device built with an input and an output PM fiber. It is characterized with low insertion loss, high extinction ratio, high isolation, high return loss and excellent environmental stability and reliability. It is widely used in EDFA, Raman amplifier, fiber lasers, optical fiber sensors and instrumentation.


Key Features:

* Low insertion loss

* High extinction ratio

* High isolation

* Excellent stability and reliability


Applications:

* Fiber amplifier

* Fiber lasers

* Fiber Sensors

* Instrumentation

* Type B: Both axis working, Type F: for Fast axis blocked.

* IL is 0.3dB (1310~1550nm) or 0.5dB (1064nm) higher, RL is 5dB lower and ER is 2dB lower for each      connector added. The default connector key is aligned to slow axis.
