摘要： A method and system for regulating the decision threshold and the sampling clock phase of a data regenerator for a binary signal, wherein error correction signals for erroneous 1-bits and 0-bits are used for regulating the decision threshold of a decision stage, and further phase correction signals between transitions of binary signals serve for the phase regulation of a sampling clock signal.

摘要： In a method for determining a power of an amplified spontaneous emission in an optical fiber amplifier for a WDM signal, wherein the optical fiber amplifier includes at least a first amplifier stage having a predetermined output power set for a measured input power, a first mean inversion is determined for the first amplifier stage. A first output power of the amplified spontaneous emission is determined at an output of the first amplifier stage by reference to tabulated values which depend on the first mean inversion.

摘要： A method for pre-emphasising transmitted signals in channels for multiplex signals along a transmission path comprising supply and/or branch points is provided. According to the method, relative degradations of the signal-to-noise intervals between transmitted signals via any category or group of channels—i.e. express and add or drop channels or add-drop channels are taken into account. A point-to-point link and for transparent optical networks may be used. To this end, the average signal powers of different channel groups are set relative to one another in order to obtain predetermined signal-to-noise intervals for each group. In addition, the signal-to-noise intervals within a channel group are equalized at their termination points. Regulation protocols for controlling the pre-emphasising steps are provided.

摘要： The invention relates to a method for easily and rapidly preemphasizing an optical multiplex signal transmitted by an emitter to a receiver consisting wherein signal-to-noise ratios are equalized by means of simple measurement or new adjustment of signal power on the bandwidth of the optical multiplex signal, at least in the receiver, instead of measuring the noise output power or the signal-to-noise ratio. Said invention is based on a balance of the signal-to-noise ratios which are authorized by a transmitting system, in which the spectral influences of gain profiles, noise effects and dampings are taken into consideration. In particular, when DWDM transmission techniques are applied, in which adjacent channel spacings of the optical multiplex signal are very low, the inventive method makes it possible to use a small number of sensitive and high-resolution measuring instruments for pre-emphasis control.
