Abstract:
1. An optical transmission system for high-bit-rate transmission of optical signals comprising N optical fiber link sections, with each optical fiber link section including one optical fiber and one dispersion compensation unit, the absolute-magnitude compensations of the first to Nth dispersion compensation units being dimensioned such that the first to N−1-th fiber link sections are respectively overcompensated by approximately a same absolute-magnitude overcompensation, and an absolute-magnitude compensation of the Nth dispersion compensation unit being dimensioned such that an accumulated fiber dispersion at an output of the optical transmission system is substantially compensated, wherein the absolute magnitude overcompensation is fixed by a quotient of a calculated total absolute-magnitude compensation and the number N of the fiber link sections, and wherein the total absolute-magnitude compensation is based on a minimum absolute-magnitude compensation required for the recovery of data from an optical data signal in the optical transmission system, said minimum absolute-magnitude compensation compensating one of the fiber link sections to obtain a signal-to-noise ratio that allows error-free reconstruction of the data signal at the end of a second fiber link section.
