Title: Method and system for converting an optical received pulse train into an electrical output pulse train

Abstract: The aim of the invention, which concerns a method and a system for converting an optical received pulse train into an electrical output pulse train, is to create a method and an associated circuit arrangement for converting an optical received pulse train into an electrical output pulse train whereby achieving an improvement in transmission quality and a reduction in latency time. According to the invention, the aim, with regard to the method, is achieved by virtue of the fact that: the current pulse train is converted in a controlled manner into a first voltage pulse train; the first voltage pulse train is converted into a second voltage pulse train by controllably limiting its amplitude; according to the amplitude of the second voltage pulse train, a third voltage pulse train, which is free from a static offset of the second voltage pulse train, is generated so that it is lower than a first amplitude quantity, and the third voltage pulse train, which is free from a dynamic offset, is generated so that it is greater than a second amplitude quantity that is greater than the first amplitude quantity; in the event of a packet pause, the amplitude of the third voltage pulse train is set to zero, and; the output pulse train is generated from the third voltage pulse train.
