Layer-stranded single Armored and Double Sheathed Optical Cable


                                   ■   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. The cable core is filled
                                        with the filling compound to protect it from water ingress, over
                                        which a thin PE inner sheath is applied. After the PSP is longitudinally
                                        applied over the inner sheath, the cable is completed with a PE
                                        outer sheath.
