General Information:

PMF products can be used in fiber optic gyroscope as well as other areas of polarization-dependent devices, this product has a very low optical attenuation characteristics and excellent birefringence properties can be used to meet a variety of requirements. PMF using PCVD (plasma enhanced chemical vapor deposition) process, having a refractive index distribution of accurate, cross-sectional geometry symmetry, vertical uniformity, excellent optical performance characteristics. PMF using UV-curable double coating layer structure, the fiber environment, stable performance, can be used in -50 ℃ to +85 ℃ temperature range.
