PMJ-D Series Short-wavelength Polarization Maintaining Fiber Patchcords

Connet PMJ-D series short wavelength polarization maintaining fiber patchcords are specially designed for short wavelength applications, ranging from 350nm to 900nm. The typical working wavelength is 399nm, 405nm, 509nm, 532nm, 638nm and 780nm.

Connet PMJ-D series short wavelength 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 short wavelength 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. For fiber to free space applications, AR-coated patchcords are also available.
