Between an optical fiber (LF, LFB, LFB) and a surrounding core covering (AH, AH, SB) of an optical transmission element (OEto OE) there is at least one dry and compressible fixating element (FEto FE), which surrounds the optical fiber totally or partially, and which exerts a defined contact pressure against the core covering and against the optical fiber for fixating the optical fiber in the longitudinal direction of the transmission element. The fixating element is further formed and positioned in such a way, that position changes of the optical fiber due to bending or elongation are possible. In this way, unallowable attenuation increases in the optical fiber due to bending or position changes can be avoided.

Optical transmission element

A cable network with a light waveguide cable which is introduced in the pipeline of an existing pipeline system. The light waveguide cable is arranged along a line, preferably at the vertex of the pipeline, and is provided with a protective layer so that a smooth transition exists between the wall surfaces of the pipeline and the cable.

Cable network with light waveguide cable for installation in pipelines of existing supply line systems

In the method for manufacturing a cable (CA,), the individual leads (AD,through ADn) are supplied to a stranding apparatus (RE, RA) that produces a stranded bundle (SB,), whereby the material (MMA,) for the cable cladding (MA,) is applied onto the stranded bundle (SB,) produced in this way with an extruder head (EK,), and the stranding point for the stranding lies in the region of the extruder head (EK,). The individual leads (AD,through ADn) are already brought into contact with the material (MMA,) for the cable cladding (MA,) when or before they have just been completely stranded to form the stranded bundle (SB,).

Method and apparatus for producing a cable

A chamber element for an optical cable includes an opening for waveguides, which opening is defined by a chamber floor and two legs extending therefrom. The legs are shaped so that a resultant radial force proceeds inside the cross section of the legs as the force is directed toward a center axis of the cable.
