Abstract
The invention relates to optical fiber cables and, more specifically, to an optical fiber cable especially suited for blown installation or pushing installation in microducts of small diameter. An exemplary microcable for installation in small microducts has an outer sheath as buffer tube that holds a plurality of optical fibers without a layer of strength elements stranded around the outer sheath, which is made of one single thermoplastic material.
