DCM Dispersion Compensation Device


Fiberroad's Dispersion Compensation Module Device is 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.



- 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
