The Polarization Maintaining Fiber Isolator features low insertion loss, high extinction ratio and excellent stability and reliality.They are ideal for polarition maintaining fiber laser, fiber amplifier, sensor and widely used in high speed communication systems and istrumentation applications.

The PM isolator is a two port micro optic device build with PM fiber. PM isolator guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction.
