Dispersion Compensating Modules

Fibrain dispersion compensating modules are used in long-range transmission for compensation of chromatic dispersion. Chromatic dispersion is a phenomenon that significantly lowers the quality of high bit rate signals (from 10Gb/s upwards) and typically its compensation is necessary in links longer than 70 km.

 

Features

  • low insertion loss
  • low PDL loss
  • wide bandwidth
  • dispersion slope matched to transmission fiber

Applications

  • CWDM and DWDM transmission
  • long haul networks
  • CATV transmission
