20km Dispersion Compensation Fiber

20km Dispersion Compensation Fiber

  • 20km Dispersion Compensation Fiber

Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion. The main constituent of DCM is DCF (Dispersion Compensation Fiber) with a negative chromatic dispersion value within the wavelength range between 1525nm and 1565nm. 

The module offers a high level of compensation while maintaining a low flat insertion loss as well as a low latency. When combined with EDFA and OEO, DCM provides a simple, reliable, and cost-effective long-haul transport solution, making signals go further without regeneration.
