Polarization Maintaining Fiber Optic PM Isolator
High-performance PM isolators operating at 1310nm, 1550nm, and 2000nm wavelengths, designed for ICT and AI computing applications.
Product Overview
The Polarization Maintaining Isolator is a two-port micro-optic device built with PM panda fiber. This advanced optical component features low insertion loss, high isolation, high extinction ratio, and exceptional reliability and stability. The device guides optical light in one direction while effectively eliminating back reflection and back scattering in the reverse direction.
Available with bare fiber or 900μm jacket cable configurations, these isolators support various wavelengths including 1310nm, 1550nm, 2000nm, and other custom specifications.
