Abstract (en)

[origin: WO2005076509A1] The polarisation-multiplexed signal (PMS) contains two data signals (OS1, OS2) that are orthogonally polarised in relation to one another. Their carrier signals (CW1, CW2; CWX, CWY) are derived from the same source and thus have the same wavelength. The phase difference between the carrier signals (CW1, CW2; CWX, CWY) is adjusted or regulated in such a way that it corresponds to 90 DEG . Said phase difference of the carrier signals (CW1, CW2; CWX, CWY) permits the susceptibility to polarisation mode dispersion to be significantly reduced.
