Intambo ye-Droptical Cable ikwabizwa ngokuba yi-Bow-type drop cable (ye-indoor wiring). Iyunithi yonxibelelwano optical (ifiber optical) ibekwe embindini, kwaye amalungu amabini ahambelanayo non-metallic amandla (FRP) okanye amalungu amandla metal ibekwe kumacala omabini. Ekugqibeleni, i-extruded emnyama okanye emhlophe , I-polyvinyl chloride eGrey (PVC) okanye i-halogen-free-smoke material (LSZH, umsi ophantsi, i-halogen-free, i-flame retardant) ene-sheathed. Intambo yesikhumba yangaphandle ine-self-supporting wire ejingayo kwi-figure-8 shape.
Ngokuqhelekileyo, kukho i-G657A2 i-fiber optical, i-G657A1 i-fiber optical, kunye ne-G652D i-fiber optical. Kukho iindidi ezimbini zokuqiniswa kweziko, ukuqiniswa kwesinyithi kunye nokuqiniswa kwe-FRP engeyiyo yentsimbi. Iziqinisekiso zesinyithi zibandakanya ① ucingo lwentsimbi enephosphated ② ucingo lwentsimbi yobhedu ③ ucingo lwentsimbi ④ ucingo lwentsimbi olugqunywe (kuquka ucingo lwentsimbi yephosphate kunye nocingo lwentsimbi olufakwe iglu). Iziqinisekiso ezingezizo ezentsimbi ziquka ①GFRP②KFRP③QFRP.
Isingxobo sentambo yesikhumba ngokuqhelekileyo simhlophe, simnyama, kwaye singwevu. Imhlophe isetyenziswa ngokubanzi ngaphakathi, emnyama isetyenziswa ngaphandle, i-UV-resistant kunye nemvula. Izinto ze-sheath ziquka i-PVC i-polyvinyl chloride, i-LSZH i-halogen-free-free-flame-retardant sheath material. Ngokubanzi, abavelisi bahlula i-LSZH imigangatho ephantsi ye-halogen-free flame retardant ibe ziindidi ezintathu: i-non-flame retardant, i-flame retardant ngokutshisa okukodwa ngokuthe nkqo, kunye ne-flame retardant kwii-bundle.
Iingcingo zokuxhoma intambo yangaphandle inokuxhasa ngokubanzi i-30-50 yeemitha. I-Phosphating steel wire ithatha i-0.8-1.0MM, i-galvanized steel wire kunye ne-rubberized steel wire.
Iimpawu zekhebula ezigqunyiweyo: ukugoba okukhethekileyo kwe-fiber optical, ukubonelela nge-bandwidth enkulu kunye nokuphucula ukuhanjiswa kwenethiwekhi; I-FRP ezimbini ezihambelanayo okanye i-metal reinforcements yenza i-cable optical ibe nokumelana kakuhle nokukhusela i-fiber optical; intambo ye-optical inesakhiwo esilula, ubunzima obulula, kunye nokusebenza okunamandla; uyilo olulodwa lwe-groove, kulula ukuyixobula, kulula ukudibanisa, ukwenza lula ukufakela kunye nokugcinwa; Umsi ophantsi we-halogen-free-flame-retardant polyethylene sheath okanye i-PVC-retardant sheath ye-PVC, ukhuseleko lokusingqongileyo. Inokudityaniswa neentlobo ngeentlobo zeziqhagamshelo kwisiza kwaye inokugqityezelwa kwisiza.
Ngenxa yokuthambile kwayo kunye nokukhanya, ikhebula lokulahla lisetyenziswa ngokubanzi kwinethiwekhi yokufikelela; igama lenzululwazi lentambo yokulahla: intambo yebhabhathane emile okwelothe yenethiwekhi yofikelelo; kuba imilo yayo imile okwebhabhathane; ikwabizwa ngokuba yintambo yokubona emile njengebhabhathane, iFigure 8 optical cable. Imveliso isetyenziselwa: kwi-wiring yangaphakathi, umsebenzisi wokugqibela usebenzisa ngokuthe ngqo ikhebula; kwintambo yokukhanya yesakhiwo engenayo; yocingo lwangaphakathi lomsebenzisi kwi-FTTH.
