METHOD FOR TRANSMITTING OPTICAL SIGNALS MULTIPLEXED BY POLARIZATION Russian patent published in 2008 - IPC H04B10/148 

FIELD: radio engineering.

SUBSTANCE: in accordance to the method, at transmitting side binary signals (A, B, C, D) are transformed to two optical signals (QPS1, QPS2), which are combined in form of signal (PMS) multiplexed by polarization and then transmitted. At receiving side, division is conducted onto two orthogonally polarized signal components (PS1, PS2), which are linearly transformed to orthogonal electric components (I₁, Q₁; I₂, Q₂) and injected into multidimensional filter. Aforementioned filter replaces polarization regulator and again restores values of signals (I₁₁+jQ₁₁; I₁₂+Q₁₂), which correspond to optical signals (QPS1, QPS2) of transmitting side. Additionally it is used to compensate distortions in signals.

EFFECT: increased traffic capacity of signal transmissions and reduced costs.
