Layer-standed Reinforced Armored and Double Sheathed Optical










                                   Introduction

                                   ■   The  fibers are placed in a loose tube made of PBT. The
                                        tubes are filled with a water-resistant filling compound.
                                        A steel wire sometimes sheathed with PE for cable with 
                                        high fiber count, locates in the center of core as a metallic
                                        strength member. Tubes (and fillers) are stranded around
                                        the strength member into a compact and circular cable core.
                                        An Aluminum Polyethylene Laminate is applied around
                                        the cable core, which is filled with the filling compound to
                                        protect it from water ingress. Then the cable core is covered
                                        with a thin PE inner sheath. After the PSP is longitudinally
                                        applied over the inner sheath, the cable is completed with
                                        a PE out sheath.
