Abstract (en)

[origin: DE10236603A1] A method for transmitting at least first and second data signals (ds1, ds2) involves initially modulating the first and second data signals on to side-bands (SB1,SB2) respectively, during which the first and second side-band modulated signals (ms1, ms2) are mutually orthogonally polarized and combined to form an optical multiplex signal for transmission. On the reception side the optical multiplex signal is fed into a polarization splitter (PBS), via a polarization corrector (PTF), for separating into first and second modulated signals. The first and second side-band modulated signals are then converted into first and second electrical signals (es1, es2) which are evaluated/weighted to derive at least one control/regulating signal (rs) for regulating the polarization corrector (PTF).
