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.
