Abstract

A system is disclosed for point-to-multipoint data communications between a central station and a plurality of terminals connected to each other and to the central station by a network, in particular a passive optical network. Data transmission is carried out by time division multiplexing (TDM/TDMA). The central station has a d.c. coupled receiver with an amplifier for the optoelectrically converted signal, a memory for storing at each terminal a value corresponding to the peak value level, and a comparator that compares the signal to a reference voltage (V ref) derived from the peak value level of the corresponding burst and derives therefrom the digitalised signal. In order to reduce hardware complexity, the amplifier has a plurality of parallel amplifier units with constant amplification factors (G1, G2) that are alternatively selected by the control unit depending on the previously stored value of the peak value level (V peak) of the corresponding burst. Another comparator compares the amplified signal to the peak value level of the corresponding burst so that when a deviation is detected the stored value of the peak value level and the amplification factor for the present burst are adapted step by step.
