PMJ-LMA Series Polarization Maintaining Fiber Patchcords

Short Description:

Connet selects high-precision FC fiber optic connectors and ceramic ferrules for high-quality polarization-maintaining fiber jumpers. The operating wavelength range covers segment wavelengths (350-900 nm) and near-infrared wavelengths (900-1650 nm). And the mid-infrared wavelength (1900-2200nm) band, the product line is rich, to meet the needs of various applications.

    Connet PMJ-LMA series polarization maintaining fiber patchcords adopt lager mode area (LMA) fiber, and specially designed for high power fiber laser and amplifier. Connet develops a wide range of lager mode area fiber patchcords in the 1µm, 1.5µm and 2µm bands for various applications.

    Connet PMJ-LMA series polarization maintaining fiber patchcords adopt PANDA type lager mode area 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-LMA series 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.
