Non Metallic Duct Cable (LSZH Sheath)

The Optical fibres are housed in loose tubes that are made up of high-modulus plastic and filled with thixotropic jelly. The tubes (and fillers) are stranded around the central strength member to form a cable core. The core is covered by water-blocking tape and yarns. Finally, a LSZH outer sheath is extruded to make the cable structure complete.
