摘要： The invention relates to a method for transmitting at least one first and second data signal in polarization multiplex. To this end, the invention provides that, in a first step, the first data signal is, on the transmit side, modulated to a sideband of a first carrier signal for generating a first sideband-modulated signal, and the second data signal is modulated to a sideband of a second carrier signal in order to generate a second sideband-modulated signal. In a second step, the first and second sideband-modulated signal are subsequently polarized orthogonal to one another, combined to form an optical multiplex signal and transmitted. In a third step, the optical multiplex signal is, on the receive side, guided via a polarization control element to a polarization splitter that separates the transmitted optical multiplex signal into the first and second sideband-modulated signal. In a fourth step, the first sideband-modulated signal is converted into a first electrical signal and/or the second sideband-modulated signals are/is converted into a second electrical signal. In a fifth step, the first and/or second electrical signal are/is evaluated and at least one control signal for controlling the polarization control element is derived on the basis of this evaluation.

摘要： In an optical transmission system, a first modulated signal with a first transmission bit rate is generated at the transmitting end by modulating a first carrier signal with the first data signal, using a nonreturn to zero coding, and a second modulated signal with a second transmission bit rate is generated by modulating a second carrier signal with the second data signal, using a return to zero coding. The first and second modulated signal are polarized orthogonally with respect to one another and combined to form an optical multiplex signal and transmitted. At the receiving end, the optical multiplex signal is conducted via a polarization control element to a polarization splitter which splits the optical multiplex signal into the first and second modulated signal. The first modulated signal is converted into a first electrical signal and the second modulated signal is converted into a second electrical signal, the spectral component of the first and/or the second electrical signal is determined at the frequency corresponding to the first transmission rate and from this at least one control signal is derived for controlling the polarization control element.

摘要： A compensation system for adaptive equalization of an optical signal, wherein an optical filter, whose complex coefficients are adjustable, is used for signal equalization. The quality of the optical signal is used, after conversion to an electrical data signal, as a control criterion. The compensation device can largely compensate for distortion produced by dispersion, polarization mode dispersion or self phase modulation. An optical compensation filter with a wide free spectral range is used to compensate for the wavelength-dependent dispersion in a wavelength-division multiplexed system. The setting of the filter may be fixed, or may be adjusted adaptively in a closed control loop.

At the receiving end, the optical multiplex signal is conducted via a polarization control element to a polarization splitter which splits the optical multiplex signal into the first and second modulated signals. The first modulated signal is converted into a first electrical signal and the second modulated signal is converted into a second electrical signal, the spectral component of the first and/or of the second electrical signal at the differential frequency is determined and from this at least one control signal is derived for controlling the polarization control element.
