PM Components (Micro Optics Type)
1. Description:
The Polarization Maintaining Components are characterized with low insertion loss, high return loss, high extinction ratio and excellent environmental stability and reliability. They are ideal for polarization maintaining fiber amplifiers, fiber lasers, high speed communication systems and instrumentation applications.
