PMJ-D Series Mid Infrared Polarization Maintaining Fiber Patchcords

Connet PMJ-D series mid-infrared polarization maintaining fiber patchcords are specially designed for mid-infrared wavelength application, ranging from 1900nm to 2200nm. The typical working wavelength is 1908nm, 1940nm, 1950nm and 2050nm.

Connet PMJ-D series mid-infrared polarization maintaining fiber patchcords adopt PANDA type polarization maintaining fiber and the slow Axis alignment, along with high-precision FC fiber connectors and ceramic ferrules for high quality.

Connet uses each of the most demanding processes to carefully craft each polarization-maintaining fiber patchcords to ensure high return loss and high polarization extinction ratio(PER), concentricity deviation, control of shaft angle deviation and strict reliability experiments make these polarization-maintaining fiber patchcords meet the industry's highest quality standards.

Connet PMJ-D series mid-infrared polarization maintaining fiber patchcords use Narrow Key (2.0mm) FC fiber optic connectors with multiple connection options, including FC / UPC, FC / APC, and hybrid FC / UPC to FC / APC patchcords.
