Verfahren zur kanalweisen Einstellung von Sendesignalleistungen eines Wellenlängenmultiplex-Übertragungssystems

摘要

For exact level balancing or signal-to-noise ratio balancing of received signals in a wave-length-division multiplex transmission system, the associated transmitted signal power levels are adjusted. If the maximum permissible dynamic range is exceeded, the individual transmitted signal power levels are compressed, while the total transmitted signal power level is kept at least approximately constant.
