Abstract
Abstract The cable core containing one or more optical waveguides is protected from longitudinal and transverse forces by being loosely disposed within a sheathing. The sheathing consists of a tubing which is divided into two sections in the longitudinal direction. Following the placement of the cable core in one tubing section, the latter is closed by placing the other tubing section thereon, in such a way that the two tubing sections are thereafter inseparably connected to one another.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
173 words
An optical communication cable comprising: a cable core having at least one optical waveguide therein; a sheathing of a tubular glass fiber reinforced cured plastic material surrounding and spaced radially outwardly from the outside of said cable core to form a space therebetween, said sheathing including first and second longitudinally-extending sections, each of said sections having two opposed longitudinally extending sides, and each of said sides having an inner edge facing the space and an opposed outer edge, and a first strip extending in a circumferential direction longitudinally along the outer edge of each of said sides of said first section to form an opening in said first section and a second strip extending in a circumferential direction longitudinally along the inner edge of each of said sides of said second section, each of said second strips being positioned in the respective openings in said first sections so as to provide a locking connection with said first sections; and a layer of a protective material disposed on the outer surface of said sheathing.
Claim 2
Dependent Claim
173 words

Claim 3
Dependent Claim
15 words
The cable of claim 1 wherein said first section is bonded to said second section.
