摘要： A method for measuring the signal quality of an optical data signal is provided. To measure the signal quality, and in particular the signal-to-noise ratio of an optical data signal which has data-free time intervals, the signal strength of the transmitted optical data signal is measured during a data transmission. The signal strength of the noise signal is determined during the data-free time intervals. The signal-to-noise ratio is determined and used as a criterion for the signal quality of the optical data signal.

摘要： In the high-bit-rate transmission of optical signals in an optical transmission system having N optical fiber link sections with, in each case, one optical fiber and one dispersion compensation unit, the absolute-magnitude compensations of the first to Nth dispersion compensation units are dimensioned in such a way that the first to N−1-th fiber link sections is/are overcompensated, in each case, by approximately the same absolute magnitude overcompensation. Furthermore, the absolute-magnitude compensation of the Nth dispersion compensation unit is dimensioned in such a way that the accumulated fiber dispersion at the output of the optical transmission system is virtually completely compensated.

摘要： Bidirectional data signals are exchanged between a central unit and a plurality of network terminals.

The optical network units select their associated downstream signal and generate an associated upstream signal.
