PMF Polarization Maintaining Fiber Optic Cable Singlemode 250um
Polarization maintaining fibre (PMF) is specially designed for fibre optic gyroscopes (FOGs) and polarization-sensitive components applications. This kind of fibre exhibits extremely low attenuation and excellent birefringence characteristics, and uses in a variety of demanding applications. PMF is manufactured through the high precision Plasma Chemical Vapor Deposition (PCVD) process. This process produces preforms with precise refractive index profiles, material uniformity and dimensional tolerances, therefore, makes fibres with excellent birefringence, low attenuation and extremely tight tolerances. With dual-layer, UV-cured Acrylate coating, Polarization maintaining fibre has high environmental stability performance over the temperature range of -45 ℃ to +85 ℃ (-49 ℉ to +185 ℉ ).
