Passive Dispersion Compensation Module




  • Dispersion Compensation Module(DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion and compensates for chromatic dispersion in fiber that causes the light pulses to spread and generate signal impairment.
  • This module provides fixed chromatic dispersion compensation for high-speed metro core, regional, and extended-haul DWDM networks and offers a high level of compensation while maintaining an ultra low flat insertion loss as well as a low latency.



  • Single-slot 1U 19″ rack mount design
  • Compatible with C-Band DWDM optical channels
  • Purely passive component supporting high reliability
  • Compensates standard single-mode G.652 optical fiber
  • Protocol transparent ranging from 10 Mbps to 40 Gbps
  • Operation with a booster amplifier or a pre-amplifier to get excellent character
  • Low end-to-end insertion loss
  • Compliance with RoHS
  • Operating temperature: -5℃~55℃; Storage temperature: -45℃~85℃



  • DWDM Optical transmission system
  • CATV Optical transmission system
  • SDH Optical transmission system
