Abstract:
1. A wavelength division multiplexing optical fiber transmission line comprising a dispersion management transmission line, said dispersion management transmission line consisting of 3 to 6 pairs of fiber sections arranged in series without intervening elements for configuration, each of said pairs including a positive dispersion fiber section and a negative dispersion fiber section, and wherein wavelength dispersion of said positive dispersion fiber section is positive; wherein dispersion of said negative dispersion fiber section wavelength dispersion is negative, alternatively arranged, and wherein signal deterioration caused by interaction between the accumulated dispersion is reduced, wherein a mean dispersion value within the dispersion management transmission line is ±250/(L·N)±0.5, where L is the length of the dispersion management transmission line, and N is a span number of dispersion management transmission channels that are consecutively inserted between block dispersion compensators.
