Abstract
Abstract Optical communication cable consisting of a cable core having light waveguides (1) and a sheath of synthetic resin which surrounds same and has glass fiber elements taking up tensile forces. The glass fiber elements (10) are formed into at least one uniform strand (16) by means of a binder (11) of synthetic resin and in the cable sheath constitute at least a part by volume of 10%, the part by volume in the strand being at least 70%.

Claim 1
Independent Claim
87 words
An optical communication cable consisting of a cable core having optical fibers and sheath of synthetic resin surrounding said optical fibers and having glass fiber elements taking up tensile forces, the improvement therein comprising a binder of synthetic resin, said binder forming and holding said glass fiber elements in at least one uniform strand, said fibers being distributed in said resin, said fiber elements constituting at least 10% by volume of said cable sheath and at least 70% by volume of said at least one uniform strand.
Claim 2
Dependent Claim
87 words
An optical communication cable consisting of a cable core having optical fibers and sheath of synthetic resin surrounding said optical fibers and having glass fiber elements taking up tensile forces, the improvement therein comprising a binder of synthetic resin, said binder forming and holding said glass fiber elements in at least one uniform strand, said fibers being distributed in said resin, said fiber elements constituting at least 10% by volume of said cable sheath and at least 70% by volume of said at least one uniform strand.
