Precise alignment (especially polarization axis matching) by fusion splicers minimizes polarization crosstalk at splice points. Polarization maintaining (PM) fibers are unique optical fibers that are manufactured specifically to retain the polarization state of light signals and are required for operation in fields such as sensors, modulators, and coherent communication (communication systems that require some form of phase. The TUNE PM 500 Splicer is an innovative device designed for fusion splicing polarization-maintaining (PM) fibers. It enhances traditional fusion splicing by incorporating manual rotary fiber holders and specialized software, enabling precise manual alignment of PM fiber axes while automating core. Different types of polarization-maintaning fibers are designed depending on the geometry of the stress elements: “PANDA“ fibers, “Bow-Tie“ fibers or “Oval-Inner Clad“ fibers. The polarization-maintaining fiber cables made by Schäfter+ Kirchhoff typically use fibers of type PANDA. The following is an overview of its specific application.
