DCM Dispersion Compensation Device
● DWDM system dispersion compensation and broadband low residual dispersion
● G.652 fiber C-band 100% slope compensation (standard value)
● Low insertion loss
●  Low polarization mode dispersion
● Performance indicators by Telcordia GR-2854-CORE standard certification
● Reliability by Telcordia GR-1221-CORE standard certification
HTF DCM Dispersion Compensation Device 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 80 kilometers.
