METHOD FOR TRANSMITTING ADDITIONAL DATA SIGNAL AND USEFUL DATA SIGNAL OVER OPTICAL LINES Russian patent published in 2003 - IPC

Abstract RU 2202150 C2

FIELD: additional and useful data transmission over optical networks. SUBSTANCE: additional data signals are transmitter over optical networks through same channel as useful data signal wherein additional data signal is converted into code sequences and the latter are superimposed with lower amplitude onto useful data signal. On receiving end additional data signal is obtained due to mutual correlation. EFFECT: provision for fitting additional and useful data signals. 12 cl, 3 dwg
