Overview
Fiberroad Technology Co. 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.
Highlights
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
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
