The optical fiber unit is positioned in the centre.Two parallel fiber reinforced plastics (FRP) are placed at the two sides.Then, the cable is completed with a black or color LSZH sheath .
The fiber ,250Um,are positioned in a loose tube made of a high modulus plastic.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 centre of core as a metallic strength member .Tubes and fillers are stranded around the strength member into a compact and circular cable core.An APL 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 outer sheath .Application: Duct/ Aerial/Direct buried .
The fibers ,250um, are positioned in a loose tube made of a high modulus plastic .The tubes are filled with a water-resistant filling compound. A steel wire locates in the centre of core as a metallic strength member. The tubes and fillers are stranded around the strength member into a compact and circular cable core .After an APL moisture barrier is applied around the cable core,this part of cable accompanied with the stranded wires as the supporting part are completed with a PE sheath to be figure 8 structure . Figure 8 cable DCTC8Y, DCTC8S are also available on request .This type of cable is specifically applied for self-supporting aerial installation .
