ABSTRACT:
A communication network (e.g., a coax network or an optical fiber network) comprises a signal distribution network (e.g., fiber node FN) for transmitting communication signals downstream over a first communication path to a plurality of end user apparatuses connected thereto. At least one end user apparatus is arranged for sending the return signals downstream over at least part of the first communication path to a converter apparatus which collects the return signals and converts them to an upstream signal for transmission over a second separate communication path to the distribution unit.
