When introducing broadband video-telephone on a large scale a considerable expansion of transmission capacity will be needed in the trunk network. This expansion might economically be achieved by the application of optical amplifiers and coherent multicarrier (CMC) techniques. When introducing the optical fibre in the subscriber-line area the distribution of television programmes is a crucial point. In the long run, broadband distribution applying cmc techniques might be a solution. Another obstacle against the introduction of optical fibres in the subscriber loop area is the high cost of optoelectronic converters. Unless optoelectronic circuits can be made less expensive by monolithic integration an extensive application of optical fibres in the subscriber loop area cannot be expected in the long run. The single-mode fibre is the suitable transmission medium for all network layers. When applying cmc technique crosstalk can occur caused by nonlinearities of the fibre. According to first experiences cmc techniques seem to be applicable not only for optical transmission but also for optical switching of informations.
