DCM Dispersion Compensation Module
The single-mode-fiber C-band 100% slope-compensation module, or dispersion-compensation module (DCM), provides broadband dispersion and dispersion-slope compensation for standard single-mode fiber (G.652) across the C band, optimizing residual system dispersion. Mature, reliable fiber technology improves optical-transmission-system performance. Dispersion values at 1550nm range from -10 to -2100ps/nm. Modules with special center-wavelength or dispersion requirements are also available.
