DCM Dispersion Compensation Device
Huanet 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 DCM 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. Function DWDM system dispersion compensation and broadband low residual dispersion Dispersion Compensation and Dispersion Slope Compensation Obtained at a specific wavelength dispersion compensation, should satisfy the following relationship: DTF × LTF + DDCF × LDCF = 0 DTF: transmission fiber dispersion; LTF: length of the transmission fiber; DDCF: dispersion of the dispersion compensating optical fiber; LDCF: dispersion compensation fiber length; Dispersion slope compensation in the band, should satisfy the following relationship: STF × LTF + SDCF × LDCF = 0 STF: dispersion of the transmission fiber; SDCF: dispersion of the dispersion compensating optical fiber According to the above two relationships obtained dispersion compensation and dispersion slope compensation, should satisfy the following relation: RDSDCF = SDCF / DDCF = STF / DTF Assuming standard single mode fiber at 1545nm wavelength dispersion of 16.7ps / nm / km, a dispersion slope of 0.060 ps / nm2 / km, RDS about 0.0036nm﹣1.
