Abstract
An optical cable comprising a central element surrounded by a layer containing a plurality of inwardly opening chambers, with each chamber receiving a stack of bands, which bands contain a plurality of waveguides. Preferably, each of the chambers is formed by a sub-element which has a U-shape in cross section and the sub-elements are formed on the cable core in a stranded manner, either by being stranded individually thereon or by being extruded individually thereon.
Claims17
In an optical cable comprising a core element with a layer surrounding the core element, said layer having sub-elements with at least one chamber and said sub-element being distributed over the circumference, each of said chambers accepting a band stack, each band stack being composed of a plurality of bands with each band comprising a plurality of light waveguides, said chambers being separated by walls, the improvement comprising the chambers being opened radially inward and the walls of the chambers having their smallest thickness adjacent the core element, said sub-element being arranged segment-shaped around the core element and said sub-elements forming a closed, ring-shaped structure in an outward direction.
A method of manufacturing an optical cable having a core element surrounded by a layer of a plurality of sub-elements arranged segment-shaped around the core element and forming a closed, ring-shaped structure, each sub-element having at least one chamber which opens radially inward toward the core element, each of said chambers receiving a stack of a plurality of bands with each band containing a plurality of waveguides, said method comprising the steps of providing a central core element, forming the layer of the sub-elements on the core element with the sub-elements arranged with the chambers opening radially inwardly toward the core element, assembling a band stack in each of said chambers, and applying an outer cladding on the layer.
