The module offers a high level of compensation while maintaining a low flat insertion loss as well as a low latency. When combined with FIBERWDM's EDFA and OEO, DCM provides a simple, reliable, and cost-effective long-haul transport solution, making signals go further without. In optical fiber communications, dispersion compensation modules (DCM) (also called dispersion compensation units, DCU) can be used for compensating the chromatic dispersion of, e., a long span of transmission fiber. normal. A DCF is a type of fiber that uses negative chromatic dispersion to compensate for the positive dispersion of the transmitting fiber to maintain the original shape of the signal pulse. It can compensate standard single mode optical fiber of 1525~1565nm effectively 1525~1565nm to fit its dispersion feature and slope characteristic.
