Dispersion Compensating Fibre (DCF)

YOFC dispersion compensating fibre is specially developed through proprietary PCVD-based technology. Taking advantages of PCVD process, YOFC is able to manufacture complex index-profile shapes accuratelly, therefore, to get the optimized products with the best compromise between insertion loss and residual dispersion over the compensated working wavelength. Customized fibres with special center wavelength and dispersion are available.
Applications
  • Single mode fibre backbone and metropolitan area networks based on recommendation G.652
  • DWDM networks
  • SDH network
  • CATV
  • Dispersion adjustment
Characteristics
  • Broad band dispersion compensating of DWDM network and extremely low residual dispersion
  • 80-120% slope compensation in C/L band
  • Low insertion loss and high negative dispersion coefficient
  • High figure of merit(FOM)
  • Low PMD
  • Performances meet the criterion Telcordia GR-2854-core
  • Reliability meets the criterion Telcordia GR-1221-core
  • Customized encapsulation type, dimension, connector type and jumper length
  • Good splicing characteristics, spliced by one discharge
