PANDA Type PMF

The PANDA type polarization-maintaining optical fiber is produced by the MCVD (Modified Chemical Vapor Deposition) process.

Description

The PANDA type polarization-maintaining optical fiber is fabricated through the MCVD (Modified Chemical Vapor Deposition) process and with a UV-curable double-layer coating structure. It possesses excellent polarization maintaining properties, precise refractive index distribution, good cross-sectional geometric symmetry and longitudinal uniformity. The PANDA type PMF can be applied to fiber optic gyroscope and the other field about polarization-dependent device. Due to
the low attenuation characteristics and excellent birefringence,it is able to meet all kinds of requirements.

Features
