Abstract: An optical IQ modulator (IQM) including two parallel Mach-Zehnder modulators (MZM1, MZM2) generates single sideband data signals. A control unit (18) generates additional optical single sideband pilot signals (PS1, PS2) positioned in a lower and a higher sideband respectively, and also further pilot signals (PS3, PS4) in both sidebands. A IQ modulator output signal (MOS) converted into electrical monitoring signals (MOS) and monitored. A control unit (18) selects control signals (CS12, CS3, CS4) and controls the IQ modulator via its bias ports (6, 7, 8) till the power transfer functions (PTF) of the Mach-Zehnder modulators (MZM1, MZM2) and the phase difference (ΔΦ) between their output signals is optimized.

Abstract: A method and a device for conveying optical data are provided, wherein an optical network unit conveys data to a terminal via dual sideband modulation, wherein the terminal processes only the upper or only the lower sideband received from the optical network unit, and wherein several dual sideband modulated signals from several optical network units partially overlap when being received at the terminal. Furthermore, a communication system is suggested comprising at least one such device.
