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.
