PM Isolator with built in polariser

Polarization Maintaining PM Isolator with built in polarizer
Fibre coupled

The PM isolator with polarizer inside designed to pass light with one specific polarization while blocking other polarization. The polarization maintaining fiber isolator is a two port micro optic device build with PM panda fiber. The device guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction. PM isolator features low insertion loss, high isolation, high extinction ratio, high reliability and stability. The device can built with 250um bare fiber pigtails, 900um pigtails or 3mm cable. PM panda fiber isolator widely used in amplifier systems, fiber optic systems and fiber lasers.
