Polarization maintaining fiber (PMF) is manufactured using the high precision Plasma Chemical Vapor Deposition (PCVD) process. This process produces preforms with precise refractive index profiles, material uniformity and dimensional tolerances, resulting in fibers with excellent birefringence, low attenuation and extremely tight tolerances.With dual-layer, UV-cured Acrylate coating, the polarization maintaining fiber provides.
