Description
The Polarization Maintaining Fiber Isolator is a two port micro-optic device built with PM panda fiber. The device guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction. The PM isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The device can be built with 250um bare fiber, 900um jacket or a 3mm cable. The PM Panda Fiber Isolator is widely used in amplifier systems, fiber optic systems and fiber lasers.
