DCM Dispersion Compensation Module
Optical Fibers
Fiberwdm
Dispersion Value [DCM module; 10KM]: typical:-318 ps/nm; max:-340 ps/nm Dispersion Value [DCM module; 20KM]: typical:-330 ps/nm; max:-346 ps/nm Dispersion Value [DCM module; 40KM]: typical:-670 ps/nm; max:-690 ps/nm
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.
