Ultra-miniaturized DCM for O+E+C Band

The ultra-miniaturized dispersion compensation module for O+E+C band can adjust the dispersion both at O+C-band for standard single-mode fibre (G.652), so as to optimize the residual dispersion of the system. At the same time, the module has ultra-low insertion loss at O+E+C-band.

Based on the newest TDCF design, mature and reliable processing technology, the module can improve the performance of optical transmission system. Also, ultra-miniaturized dimensions of the module can meet the requirement of system miniaturization.

Applications
  • Adjusting dispersion in O-band for 5G front-haul transmission system
  • Long-haul telecommunication systems with standard single-mode fibre (G.652)
  • DWDM transmission system
  • SDH transmission system
  • Cable AM television video system
Characteristics
  • Broadband dispersion compensation in DWDM system
  • Ultra-low insertion loss
  • Ultra-low polarization mode dispersion
  • Meet or exceed Telcordia GR-2854-CORE specification
  • Meet or exceed Telcordia GR-1221-CORE specification
  • Ultra-miniaturized dimensions
