摘要： The invention relates to a method and a system for controlling a PMD compensator (2). For this purpose, a measuring signal (MS) is branched off from an already compensated optical data signal (ODSK) and supplied to a polarization adjuster (2). The output signal of the latter is supplied to an optical filter unit (61) and subdivided into two optical measuring signal components (OMK1, OMK2) having different polarizations. After a respective opto-electrical conversion, the spectra are compared with each other in an analysis and control unit (81) and the PMD compensator (2) is adjusted in such a manner that they are as identical as possible.

摘要： According to the invention, various noise currents are added to the electrical data signal after the opto-electric conversion of an optical data signal, and an optimum decision threshold for the electrical data signal equipped with this noise current is determined for each noise current. Values for a median signal current and for a median noise current of the amplified spontaneous emission are subsequently determined from the value pairs of the optimum decision threshold and the added noise current in accordance with a computation rule that is based on a noise model, and the optimum signal-to-noise ratio is calculated from their quotient. The method may also be advantageously implemented by means of simple expansions of common receiver devices.

摘要： In one aspect, a WDM signal is assigned to a number of sub-bands with the channel spacing being correspondingly enlarged in each sub-band. The spectral hole burning is hereby essentially reduced, since this effect is restricted to the adjacent channels. The complete WDM signal is first pre-amplified before being divided into sub-bands.

摘要： A method of splitting an optical data signal starting with an optical data signal split into n equal data sub-signals, and an optical binary auxiliary signal with the same bit rate and phase is added to each optical data sub-signal. Each nth bit of the optical binary auxiliary has a higher level, with the phases of each of the n optical auxiliary signals showing a relative displacement of one bit. As a result, n aggregate signals are generated, each of which is fed to a decision-maker. A decision-maker threshold is set above the amplitude of the data sub-signal and below the amplitude of the aggregate signal. Each decision-maker, therefore, emits an electrical data signal with 1/n times the bit rate of the data signal.

摘要： At the transmitter end, route information is converted to allocated frequency mixes that are used to produce route signals by modulating a carrier signal. The route signals produced are placed in front of and/or after at least one data packet and are transmitted within an optical data packet stream. At the receiver end, the route information is evaluated in terms of the frequency mix used for the modulation and the data packets are switched using the route information obtained from the frequency mixes.
