Polarization-maintaining fiber, or the so-called pm fiber array and PMF fiber, can normally ensure the direction of linear polarization and effectively improve the coherent signal-to-noise ratio. In this article, the latest in FOC's series covering specialty fibers and their fabrication, we discuss polarization-maintaining (PM) fibers and the various approaches used to make them. There are several PM fiber designs – all quite different and each with its own complexities in preform. OZ Optics Limited, a recognized leader in high performing optical fiber components and subsystem module assemblies is pleased to offer a new line of 12 and 16 channels MPO/MTP® Polarization Maintaining (PM) Fiber Assemblies. Corning offers the broadest portfolio of PANDA PM fibers from wavelengths of 400-1550 nm and designs such as High NA and Flame Retardant coatings.
