Abstract:
A dispersion compensation module (DCM) for compensating dispersion of an optical fiber transmission link, the optical fiber transmission link comprising a transmission fiber, the DCM comprising:at least first and second dispersion compensating fibers, DCF1 and DCF2, respectively, DCF1 and DCF2 each having 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 having a dispersion, DTransFiber, a dispersion slope, STransFiber, and a relative dispersion slope, RDSTransFiber, and wherein DCF1 and DCF2 are selected based on their relative dispersion slopes, RDS1 and RDS2, respectively, DCF1 and DCF2 having particular, lengths, L1 and L2, respectively, the DCFs being combined with each other and with the transmission fiber, wherein 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.
