ADSS (Aerial Double Sheath Self-Supporting) lithapo tsa fiber optic li entsoe ka sebopeho se seng sa tšepe, se fanang ka thepa e ntle ea ho koala le tšireletso e matlafalitsoeng ea lehalima. Lithapo tsena li loketse hantle haholo bakeng sa ho tsamaisoa ka sefofane, e leng se etsang hore e be khetho e tsebahalang lits'ebetsong tse fapaneng, ho kenyeletsoa likhokahano tsa mehala, marang-rang a lisebelisoa, le phetiso ea data.
Joaloka moetsi ea ka sehloohong oa fiber optic cable Chaena, re fana ka litharollo tse ikhethileng tse etselitsoeng ho finyella litlhoko tse khethehileng. Tsa ronaLithapo tsa ADSSe ka hlahisoa ka meralo ho tloha ho 2 ho isa ho 288 fibers, e amohelang litlhoko tse fapaneng tsa projeke. Ka mela e 20 ea tlhahiso ea ka ntle ea cable, re netefatsa tlhahiso ea boleng bo holimo le ho nepahala.
Ts'ebetso ea rona ea tlhahiso e kenyelletsa mekhoa le lisebelisoa tse tsoetseng pele, joalo ka khoele ea aramid e tsoang kantle ho naha, e fanang ka kabo e tšoanang ea khatello ea maikutlo le ts'ebetso e phahameng ea mochini.

Lithapo tsa rona tsa ADSS li etselitsoe ho mamella maemo a thata a tikoloho, ho kenyelletsa le leqhoa le ka fihlang ho 10mm.
Ho feta moo, re fana ka bolelele ba nako eo u ka e khethang ho tloha ho 50 ho isa ho 1000 metres ho latela litlhaloso tsa bareki, ho netefatsa hore lihlahisoa tsa rona li fihlela litlhoko tse ikhethang tsa lits'ebetso tse fapaneng. Ka boitlamo ba rona ba boleng le boqapi, re balekane ba hau ba tšepahalang bakeng sa litlhoko tsohle tsa hau tsa fiber optic cable.
