Miniaturized DCM

In applications such as fibre communication and industrial laser, dispersion management is an important means to control optical properties such as impulse and nonlinearity. The miniaturized dispersion compensating module provided by YOSC can perform dispersion and dispersion slope compensation for standard single-mode fibre (G.652) in the C-band, optimize the residual dispersion of the system, and improve the performance of the optical transmission system.
Applications
  • G.652 standard single-mode fibre
  • Long distance and metro communication systems
  • DWDM transmission system
  • SDH transmission system
  • CATV cable television system
  • Dispersion adjustment
Characteristics
  • Broadband dispersion compensation and extremely low residual dispersion for DWDM systems
  • C-band 100% slope compensation for G. 652 Fibre (standard value)
  • Module miniaturization
  • Low insertion loss
  • Low polarization mode dispersion
  • The performance indicators certified to Telcordia GR-2854-CORE standard
  • Reliability certified to Telcordia GR-1221-CORE standard
  • Different packaging styles, connector types and lengths are available
