摘要： The invention relates to a multistage fiber amplifier having a first amplifying fiber, at least one further amplifying fiber connected in series with the first amplifying fiber, a pump source, a first pump signal fed to the first amplifying fiber, and a further pump signal fed to the further amplifying fiber. The multistage fiber amplifier is distinguished by the fact that a further pump signal is fed to a further amplifying fiber via a power-dependent attenuation element. The attenuation element is formed in such a way that, as the pump power increases, small further pump signals are attenuated to a greater extent than large further pump signals. The power-dependent attenuation of the further pump signal that is fed to the further amplifying fiber and therefore the increased pump signal that is fed to the first amplifying fiber result in improvements in the noise figure of the multistage amplifier.

摘要： The invention relates to a novel method for controlling a pump unit of a fiber amplifier, with which a transmitted wavelength multiplex (WDM) signal is amplified by at least a distribution of output powers of a plurality of pump sources in order to achieve a favorable noise figure of the amplified WDM signal at a variable required overall pump power. The output powers are distributed using modulation characteristics for the pump sources depending on the overall pump power required for amplification. The modulation characteristics influence the respective inversions in the fiber amplifier in such a manner that a minimum noise figure is achieved for all channels of the WDM signal at a constant gain.

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： A method for controlling a variation in gain in an optical amplifier stage and an optical amplifier. The optical amplifier stage includes a pumping device for providing pumping power and a control unit for determining a change in an input power of the optical amplifier. The method includes the steps of determining a change in an input power of the optical amplifier, adjusting a pumping power of the pumping device to a first power level for a predetermined period of time and adjusting the pumping power of the pumping device to a second power level. The second power level is able to drive the amplifier gain to a predetermined gain value after the change in the input power occurred.

摘要： An optical amplifier with improved transient performance has two amplifier stages and a gain flattening filter-inserted between the amplifier stages. A control unit generates a pump control signal for a common pump source pumping both amplifier stages. The pump control signal has a feed-forward component and a feedback component. After a drop of channels the feed-forward control circuit is responsible for the transient performance and fast gain stabilization. The characteristic of the gain flattening filter is taken into account in calculating an optimum feed-forward control signal.

摘要： The invention relates to a bidirectional optical amplifier array (VA) which is preferably used in a passive optical network (PON) system, is disposed between a first line termination (OLT) and a second line termination (ONU), and is penetrated by an optical downstream signal (OSD) in one direction and an optical upstream signal (OSD) in the opposite direction. Said optical amplifier array is composed of a first part with two branching and combining units (D1 and D2), a unidirectional optical amplifier (E1), and a transponder (T) in which the optical downstream signals and upstream signals (OSU and OSD) are separately amplified. The two signals (OSU and OSD) that run in opposite directions are amplified in a bidirectional amplifier (E2) in a second part. A constant gain is maintained in the bidirectional optical amplifier (E2) by means of the continuous downstream signal (OSD) such that the amplifier can be operated in stable conditions for the upstream signal (OSU) regardless of occurring bursts. In another embodiment, a splitter (S1) is integrated into the inventive amplifier array (VA).
