Patent ID: 7076173

Claim:
A method for dispersion compensation regulation in an optical transmission system, having dispersion compensation units, for transmitting high-bit-rate optical signals, the method comprising the steps of: forming, in a first step, a bit-rate-reduced optical signal from at least one of said high-bit-rate optical signals by an N-fold repetition at a transmitting end of each logic 1 and each logic 0 of said high-bit-rate optical signal; transmitting, in a second step, the bit-rate-reduced optical signal; determining, in a third step, a bit error rate of the transmitted bit-rate-reduced optical signal at a receiving end; regulating, in a fourth step, absolute-magnitude compensations of the dispersion compensation units such that the determined bit error rate is minimized; and repeating the second to fourth steps for the high-bit-rate optical signal.
