ADSS power optical cable adopts loose tube stranded. Optical fibers are positioned into a loose tube made of high modulus  plastics.  The tubes are filled with a Water-blocking filling compound. The tubes(and fillers) are stranded around FRP as a non-metallic central strength member into compact and circular cable core. After the cable core is filled with filling compound, it’s covered with a thin polyethylene(PE) inner jacket. After two layer of Aramid yarns are applied in two directions over the inner jacket as strength member, the cable is completed with PE or AT(anti-tracking) outer jacket.
