Shanghai Gengyun Industrial Co., Ltd
Polarization maintaining special optical fiber is manufactured using the PCVD (plasma chemical vapor deposition) process. It has the characteristics of precise refractive index distribution and good cross-sectional geometric symmetry. It has good longitudinal uniformity and excellent optical performance.
Polarization-maintaining special optical fiber uses a double UV-cured coating structure. The optical fiber has stable environmental performance. It can be used in a temperature range of -45℃ to +85℃.
Product Applications
- Fused-cone polarization-maintaining coupler;
- Special optical fiber mainly used for fiber polarization sensor;
Product Features
- Good geometric uniformity;
- High stability and reliability;
