Polarization Maintaining dual stage Isolator TGG based
(780, 808, 850, 880, 980, 1030, 1064, 1080nm)
The Polarization Maintaining Optical 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 dual stage isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The PM Panda Fiber Isolator is widely used in amplifier systems, fiber optic systems and fiber lasers.
GEZHI Photonics also produce compact size PM optical isolator, circulator, coupler/splitter, WDM, optical switch, combiner, PBS etc.

Note:
1.Above specifications are for device without connector, If with connector, IL will be 0.3dB higher, return loss with be reduce 5dB and Extinction Ratio will reduce 2dB.
2. If there is pulse application, please be sure to inform us of pulse energy and peak power.
