Abstract
Abstract An optical cable network constructed with light waveguide cables for one or more transmission systems comprising a plurality of existing and planned connecting points for individual system nodes. In order to facilitate the network set-up, as well as the network expansion, all existing and planned connecting points of an optical cable network are connected in series with one another by means of through extending light waveguide cables that comprise a plurality of fibers. All fibers are laid in the multiple loops at each connecting point for the formation of a cable reserve, with only the fibers needed for a system connection being cut and spliced to components for the connecting point.

Claim 1
Independent Claim
164 words
In an optical cable network constructed with light waveguide cables for one or more transmission systems selected from ring systems, star systems and bus systems, said cable network comprising a plurality of existing and, respectively, planned connecting points for individual system nodes, the improvements comprising all existing and, respectively, further planned connecting nodes of the optical cable network being connected in series with one another by means of a prescribed plurality of through light waveguide leads, which are each composed of two fibers, in one or more light waveguide cables, a number of leads of said plurality of through light waveguide leads being determined based on the maximum size of said network, each of the through light waveguide leads being laid in multiple loops at each connecting point for forming a cable reserve and only those light waveguide leads required for a system connection at each connecting point being cut to provide free ends which are connected to the system components by a splice.
Claim 2
Dependent Claim
