ABSTRACT:
A method for dispersion compensation regulation wherein, in order to transmit high-bit-rate optical signals, in a first step a bit-rate-reduced optical signal is formed from the high-bit-rate optical signal by the N-fold repetition at the transmitting end of each logic 1 and each logic 0, and in a second step the bit-rate-reduced optical signal is transmitted. In a third step the bit error rate of the transmitted bit-rate-reduced optical signal is determined at the receiving end, and in a fourth step the absolute-magnitude compensations of the dispersion compensation units are regulated in such a way that the determined bit error rate is minimized. After the bit error rate has been minimized by regulations the second to fourth steps are repeatedly carried out for the high-bit-rate optical signal.
