Mini PM Optical Fiber Devices Series

Author:Optizone Technology (Shenzhen) Limited Click: Time:2022-04-26 08:08:00


Polarization maintaining device is a general term of optical devices produced by polarization maintaining fiber. The purpose is to maintain the original polarization state of polarized light or change the polarization state when connecting or coupling the polarized light in two polarization maintaining fibers. It can be used in polarization sensitive fiber optic sensing systems such as fiber optic gyroscope and fiber optic hydrophone. It can also be used in fiber optic communication systems, fiber amplifiers, fiber lasers and other devices.


Compared with the products sold on the market, the extinction ratio of the Mini series optical fiber devices can be up to 28dB, the minimum package can be 2.5*20mm. At the same time, it has high damage threshold, high reliability and high integration.
