Polarization maintaining optical isolators provide high optical isolation while preserving the polarization states of light. These devices are essential for fiber sensor systems, coherent communication systems, optical fiber lasers, and advanced applications in ICT and AI computing.
The PM isolator delivers exceptional performance with low insertion loss, high isolation, high extinction ratio, and outstanding reliability and stability. It guides optical light in one direction while eliminating back reflection and back scattering in the reverse direction. Available with bare fiber or 900μm jacket cable configurations.
