Abstract
A dispersion compensation module (DCM) for compensating dispersion of an optical fiber transmission link is provided. The optical fiber transmission link comprises a transmission fiber and the DCM. The DCM comprises at least first and second dispersion compensating fibers, DCF1 and DCF2, respectively. DCF1 and DCF2 each have a dispersion, D1 and D2, respectively, a dispersion slope, S1 and S2, respectively, and a relative dispersion slope, RDS1 and RDS2, respectively. The transmission fiber also has a dispersion, DTransFiber, a dispersion slope, STransFiber, and a relative dispersion slope, RDSTransFiber. DCF1 and DCF2 are selected based on their respective relative dispersion slopes, RDS1 and RDS2, respectively. DCF1 and DCF2 have particular, lengths, L1 and L2, respectively. The DCFs are combined with each other and with the transmission fiber and RDS1 and RDS2 are such that the combination of the transmission fiber with the combined DCFs results in overall dispersion compensation of the optical fiber transmission link.
