DCM: Dispersion Compensation Module
optical compensation function with slope dispersion compensation for standard single-mode fiber can DCM (G.652) were dispersion and dispersion slope compensation broad band in the C-band, allowing the system to optimize residual dispersion. In the dispersion compensation value of 1545nm wavelength dispersion can reach -2070ps / nm.
The DCMs offer a high dispersion compensation level and a very low insertion loss penalty. They provide negative dispersion compensation over the full C-Band with possible distance extensions of up to 120 kilometers.
