Drop Optical Cable tseem hu ua Bow-type drop cable (rau kev xaim sab hauv tsev).Qhov chaw sib txuas lus kho qhov muag (optical fiber) tau muab tso rau hauv qhov chaw, thiab ob qho tib si uas tsis yog xim hlau cov tswv cuab (FRP) lossis cov tswv cuab muaj zog hlau tau muab tso rau ntawm ob sab.Thaum kawg, extruded dub los yog dawb, Grey polyvinyl chloride (PVC) los yog cov khoom uas tsis muaj pa taws halogen (LSZH, tsis tshua muaj pa luam yeeb, halogen-dawb, nplaim retardant) sheathed.Sab nraum zoov tawv cable muaj ib tug self-txhawb dai hlau nyob rau hauv daim duab-8 duab.
Feem ntau, muaj G657A2 optical fiber, G657A1 optical fiber, thiab G652D optical fiber.Muaj ob hom kev txhawb nqa hauv nruab nrab, hlau qhov cuab lub zog thiab tsis yog hlau FRP qhov cuab lub zog.Cov khoom siv hlau muaj xws li ① phosphate steel hlau ② tooj liab-plated steel hlau ③ galvanized steel hlau ④ coated steel hlau (xws li phosphate steel hlau thiab galvanized steel hlau coated nrog kua nplaum).Cov khoom siv tsis yog hlau muaj xws li ①GFRP②KFRP③QFRP.
Lub sheath ntawm tawv cable feem ntau yog dawb, dub, thiab grey.Dawb yog feem ntau siv sab hauv tsev, dub yog siv sab nraum zoov, UV-resistant thiab rain-resistant.Cov ntaub ntawv sheath muaj xws li PVC polyvinyl chloride, LSZH tsawg-tsim halogen-dawb nplaim-retardant sheath khoom.Feem ntau, cov tuam txhab faib LSZH tsis tshua muaj pa taws halogen-dawb nplaim retardant qauv rau hauv peb hom: non-flame retardant, nplaim retardant los ntawm ib qho ntsug hluav taws kub, thiab nplaim retardant nyob rau hauv bundles.
Sab nraum zoov kho qhov muag cable dai xov hlau feem ntau tuaj yeem txhawb nqa 30-50 meters.Phosphating steel hlau txais 0.8-1.0MM, galvanized steel hlau thiab rubberized steel hlau.
Cov yam ntxwv ntawm cov kab hluav taws xob: tshwj xeeb khoov kho qhov muag fiber ntau, muab bandwidth ntau dua thiab txhim kho kev sib txuas ntawm network;ob qho tib si FRP lossis hlau reinforcements ua rau cov khoom siv kho qhov muag tau zoo compression kuj thiab tiv thaiv cov fiber ntau optical;lub optical cable muaj ib tug yooj yim qauv, lub teeb yuag, thiab practicality Strong;tshwj xeeb groove tsim, yooj yim rau tev, yooj yim mus cuag, yooj yim installation thiab txij nkawm;Tsis tshua muaj pa taws halogen-dawb nplaim-retardant polyethylene sheath los yog nplaim-retardant PVC sheath, kev tiv thaiv ib puag ncig.Nws tuaj yeem sib phim nrog ntau hom kev sib txuas ntawm qhov chaw thiab tuaj yeem ua tiav ntawm qhov chaw.
Vim nws softness thiab lightness, poob cable yog dav siv nyob rau hauv kev nkag network;lub npe scientific ntawm qhov poob cable: npauj npaim-zoo li tus lead-hauv cable rau kev nkag mus rau network;vim nws cov duab zoo li npauj npaim;nws tseem hu ua npauj npaim-zoo li tus kho qhov muag cable, Daim duab 8 optical cable.Cov khoom siv yog siv rau hauv: rau kev siv hluav taws xob sab hauv tsev, cov neeg siv kawg ncaj qha siv cov cable;rau lub tsev cov khoom siv kho qhov muag cable;rau tus neeg siv cov kab hluav taws xob sab hauv tsev hauv FTTH.
