Description
Panda-type polarization-maintaining optical 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 PM Patch Cord
- Small axis deviation
- Various polarization-maintaining fiber types can be selected 850nm, 980nm, 1310nm, 1550nm
- Good compatibility with standard connectors
- High Return Loss
- High Extinction Ratio
- Low Insertion Loss
- Excellent environmental stability and reliability
