Bandwidth slots of the lower bandwidth for those of the data transmission connections, whose respective shortest path metric is smaller than their respective shorter distance, are allocated. Finally, bandwidth slots of the lower or the higher bandwidth are allocated for the further data transmission connections, using respective numbers of necessary OEO regenerations.

    摘要: Proposed is a method of optical data transmission. The method comprises different steps. A first optical signal and a second optical signal are generated, such that the optical signals possess a same wavelength, respective phases, which are modulated in dependence on respective data values, and respective polarization states, which are essentially orthogonal to each other. A combined optical signal is generated, by combining the optical signals, such that the combined optical signal possesses a polarization state with a predetermined variation. The combined optical signal is transmitter over an optical transmission line and received. Two time-discrete sampled signals are generated, by sampling the received optical signal along two orthogonal polarization planes. Two filtered signals are generated, by filtering the time-discrete sampled signals in the time-discrete domain, using a function that is indicative of the respective predetermined variation. Finally, respective data values are derived from the filtered signals.

    摘要: Proposed is a method of optical data transmission. A first data signal and a second data signal are received at a same sampling rate. A third data signal and a fourth data signal are generated, using the first and the second data signal, wherein the two data signals are delayed to each other by a delay time that is varied over time. The phase of a first optical signal is modulated in dependence on the third data signal, and the phase of a second optical signal with a same wavelength is modulated in dependence on the fourth data signal. The first optical signal is transmitted in a first polarization plane into an optical fibre, and the second optical signal is transmitted in a second polarization plane orthogonal to the first polarization plane into the optical fibre.

    摘要: The invention proposes a system and method for selecting an optimal optical path through which to transmit an optical signal, the optimal optical path is one of a plurality of optical paths in a transparent optical network. Each of the plurality of optical paths includes a plurality of optical elements. For each of the plurality of optical paths, a first optical signal to noise ratio is determined for each optical element in the respective optical path. Then, for each of the plurality of optical paths, nonlinear distortions caused by each optical element in the respective optical path are modelled as Gaussian noise and a second optical signal to noise ratio associated with the modelled Gaussian noise is determined. Finally, the optimal optical path is selected using the sums of the first and second optical signal to noise ratios, respectively.

    摘要: Proposed is a method for generating a look-up table for retrieving data rates for a data transmission connection. The look-up table indicates for a data rate and a transmission distance parameter a set of data rates, wherein the sum of the set of data rates is equal to or greater than the corresponding data rate. The generation of the set of data rates is performed, by determining for at least one test data transmission connection a test set of data rates, for which a number of necessary network resources is optimized. The set of data rates is determined based on the test set of data rates.
