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 in the C-Band (1525nm to 1565nm). The module offers a high level of compensation while maintaining a low flat insertion loss. When combined with EDFA and OEO, making signals go further without regeneration.
