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： A light beam which is used for transmitting a wavelength division multiplex signal is guided to a Bragg grating via an adjustable mirror. According to the angle of incidence of the light beam relative to the longitudinal axis of the Bragg grating, different transmission characteristic curves having different gradients are produced. As a result thereof, scattering of the wavelength division multiplex signal can be compensated. A second controllable mirror enables the damping to be adjusted. A control device effects a rapid correction of the scattering after data signals are connected or disconnected.

摘要： The present disclosure relates to a method for regulating a pump power of an optical amplifier, where a multiplexed broadband optical signal having several channels is amplified at a certain gain value while a change in power is detected at the input or output of the amplifier. A new pump power is calculated and adjusted based on a previously provided stable gain state of the optical amplifier after detecting the change in power such that deviations of the gain value remain minimal as planned temporary interface transients during a specific interval. The new pump power is thus calculated very accurately and quickly according to a model that takes into account the actual gain value, the wavelength dependence of active channels, aging effects, and non-linear amplification effects.

摘要： An optical amplifier contains two amplifier paths. An optical user signal (&agr;, &bgr;) is in each case supplied to an optical amplifier (EDF1, EDF2) through direction separators (RT1, RT2). Each amplifier is followed by a wavelength multiplexer (WDM1, WDM2) via which a pump signal (&ggr;1, &ggr;2) is fed in, which, via the direction separator (RT2, RT1) which is connected to its output, pumps the amplifier (EDF2, EDF1) in the other amplifier path in the direction of the user signal (&agr;, &bgr;).
