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 olugqunywe ngocingo lwentsimbi (kuquka ucingo lwentsimbi yephosphate kunye nocingo lwentsimbi olugqunywe ngeglu).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 bohlula i-LSZH imigangatho ephantsi ye-halogen-free flame retardant ibe ziindidi ezintathu: i-non-flame retardant, i-flame retardant ngokuvutha okuthe nkqo okukodwa, 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: i-fiber optical egoba ekhethekileyo, ebonelela nge-bandwidth enkulu kunye nokuphucula ukusebenza kothumelo lwenethiwekhi;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.
