METHOD FOR INCREASING DATA TRANSFER CAPACITY OF A DATA COMMUNICATIONS NETWORK, SUCH AS A CABLE TELEVISION NETWORK

摘要

The invention relates to a method for increasing the data-transmission capacity of a bi-directional telecommunications network. Optical-fibre cables are connected in parallel with optical-fibre cables of an original cable-television network. The signals coming from the supplementary-service signal source, which in the original network were combined in the head end (A) with signals coming from the television signal source, are transmited on these cables and combined with the signals coming from the television signal source in the node stations (B) and (C).
