In a hybrid fiber coaxial access network NET with forward channel and back channel of the return channel for the transmission of voice and video signals and data signals from groups of terminals used (NT1; NT2) to a sub-center (HUB). Access a group of terminals (NT1; NT2) to a common electric wire (KOAX1; KOAX2) for example via TDMA, FDMA or CDMA. An optical network termination unit (ONU) is provided with one or more electrical lines (KOAX1; KOAX2) connected. For each line or for each separate frequency band of the return channel, the optical network termination unit (ONU) includes an analog / digital converter (A / D1, A / D2) in which the received signal is digitized. At more analog / digital converters (A / D1, A / D2) are multiplexed in the individual digitized signals to a multiplexer (MUX) and then fed to a digital electrical / optical converter (E / 02). In Electrical / Optical converter (E / 02) are implemented, the multiplexed signals into optical signals and then via an optical line (FIBRE) for sub-center (HUB) transfer, in which they are further processed digitally.
