Radiation Resistant Single-mode Fibre (RRF)

YOFC radiation resistant sigle-mode fibres are developed by adjusting the composition of optical fibre and improving the process technology to meet the special application requirements of the fibre in the radiation environment. The optical properties of RRF are optimized at 1310nm and 1550nm oprerating wavelenghth. Low attenuation and low dispersion can be achieved.
Applications
  • Aerospace
  • Atomic energy
  • Medical
  • Oil/gas
  • Scientific research
Product process
  • YOFC fibre are manufactured with PCVD process. The fibres have excellent radiation resistant properties at 1310nm and 1550nm operating wavelength by special glass components and manufacturing process. Due to the accurate control of refractive index profile by PCVD process, YOFC radiation resistant sigle-mode fibres have excellent geometrical, attenuation and dispersion properties
Characteristics
  • Low dispersion and low attenuation
  • Superior mechanical protection and excellent stripping performance
  • Outstanding uniformity and geometry control
  • Low radiation loss
