Abstract
The invention relates to a bandpass filter (OFI) which is mounted downstream of an optical amplifier (OV) and allows noise to be largely reduced. In order for said bandpass filter to be able to optimally receive burst signals (BS, BS, . . . , BSN) transmitted by several user devices (ONT, ONT, . . . , ONTN) also in a central node (OLT), the bandpass filter is set to the respective received carrier frequencies (TFto TFN). Because of time constraints, this is possible only if the carrier frequencies (TF, . . . ) or associated filter setting values (FE, . . . ) have already been stored and the bandpass filter is preset.
