DCM, 20km-120KM DCF-based Passive Dispersion Compensation Module

20KM-120KM Passive Dispersion Compensation Pluggable Module 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 1528nm and 1568nm. 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. DCF-based Module Pushes Limits of Transmission Distance The pure passive DCM guarantees the normal working after the power failure, supporting high reliability. The excellent DCF (Dispersion Compensation Fiber) can properly correct or reverse the dispersion that was realized as the signal traversed the optical fiber, ensuring long-haul transmission.
