Chromatic Dispersion (CD) is a critical challenge in high-speed DWDM transmission. It stretches optical pulses and increases bit-error rates. As a result, DWDM links lose stability and reach. A DCM (Dispersion Compensation Module) reverses this distortion. Consequently, modern DWDM networks depend on DCMs to preserve signal integrity over medium- and long-haul fiber routes. … Continue reading DCM Solutions for High-Performance DWDM Systems: Why They Matter
