Radiation Resistant Single-mode Fibre
In order to meet the special application requirements of optical fibre in the radiation
environment, YOFC has developed radiation resistant single-mode fibres by adjusting
the glass composition of optical fibre and improving the process technology. Such fibres
feature fully optimized waveguide characteristics at the 1310nm and 1550nm operating
wavelengths, as well as very low attenuation and dispersion.

Characteristics
- Low attenuation and low dispersion, meeting the operating requirements of communication window
- Excellent protection properties and excellent strip force stability of the coating
- Accurate geometrical parameters, ensuring low splicing loss and high splicing efficiency
- Low radiation induced attenuation
Product Process
- YOFC optical fibres are manufactured using the PCVD process. Due to a special glass composition and post-treatment process, these optical fibres exhibit excellent radiation resistance at the 1,310nm and 1,550nm operating wavelengths. The radiation resistant single-mode fibre manufactured using the PCVD process features a precise refractive index profile, ensuring excellent geometric, attenuation, and dispersion characteristics of the optical fibre.
