• YOFC radiation resistant fibre complies with orexceeds ITU-T.G651 & IEC 60793-2-10 A1a fibre specification.
• The fibre is produced by plasma activated chemical vapor deposition (PCVD) process. the radiation resistant multi mode fibre fabricated by PCVD process has excellent radiation resistant properties at 850nm& 1300nm based on its special glass components and manufacturing proces
• Due to the accurate control of deposition of PCVD process, YOFC radiation resistant multi-mode fibre has perfect waveguide refractive index profile, which guarantees the excellent geometrical, attenuation and bandwidth characteristics
• Stable transmission property under radiation environment
• High bandwidth and low attenuation @ 850nm & 1300nm
• Good stripping and welding Properties
• Suitable for various cable structures and favorable for tight/loose tubes
