Factory best selling Tunable Filter – PMJ-LMA Series Polarization Maintaining Fiber Patchcords – Connet Laser Detail:

Connet selects high-precision FC fiber optic connectors and ceramic ferrules for high-quality polarization-maintaining fiber patchcords. 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.

The standard polarization-maintaining fiber patchcords adopt PANDA type polarization maintaining fiber, and the slow axis alignment. According to the type of fiber, Connet polarization-maintaining fiber patchcords are divided into PMJ-D series, PMJ-S series and PMJ-LMA series. The polarization-maintaining fiber with Ge-doped core, the pure silica core polarization-maintaining fiber and the large mode area (LMA) polarization-maintaining fiber are respectively used.

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 jumpers meet the industry’s highest quality standards.

Connet standard polarization maintaining fiber patchcords use Narrow Key (2.0mm) FC fiber optic connectors, and the end face polishing is UPC type or APC type.
