Description
Panda-type polarization-maintaining fiber is manufactured using PCVD (plasma vapor deposition) technology, and has the characteristics of tight refractive index distribution, good cross-sectional geometric symmetry, and excellent optical performance.
This polarization-maintaining optical fiber uses a UV-cured double-coating structure, and the optical fiber has stable environmental performance and can work in a temperature range of -50~80℃.
Features of Polarization Maintaining Patch Cord
- High environmental stability and reliability
- High isolation
- High extinction ratio
- High return loss
