Abstract
A method for producing an opto cable with a central strain relief core, a glue layer on the surface of the core, a first array of optofibre-containing tubular elements bonded to the core by the glue layer, and a porous filing material filling the space between the tubular elements and the glue on the surface of the strain relief core. At least a second array of optofibre-containing tubular elements is bonded to the first array by surrounding the first array of tubular elements and the filling material with a layer of glue which bonds the second array of tubular elements to the structure. Filling material is added between the tubular elements of the second array and the layer of glue. Additional concentric arrays of glue layers, tubular elements, and filling material can be added in the same manner. A casing surrounds the outermost concentric array of tubular elements.
