Cov xaim xaim kuj tseem hu ua lub phaj-zoo li tus xaim xaim (rau cov xaim sab hauv tsev), uas yog muab qhov chaw sib txuas lus kho qhov muag (optical fiber) nyob rau hauv qhov chaw, thiab muab ob qho tib si uas tsis yog xim hlau cov tswv cuab (FRP) lossis cov tswv cuab ntawm cov khoom siv hlau. ntawm ob sab.Thaum kawg, extruded dub lossis dawb, grey polyvinyl chloride (PVC) lossis cov khoom siv tsis muaj pa halogen (LSZH, cov pa luam yeeb tsawg, tsis muaj halogen, nplaim hluav taws) sheathed.Sab nraum zoov poob cable muaj tus kheej txhawb nqa dai hlau hauv daim duab-8 zoo li.
Qhov poob cable feem ntau muab faib ua 1 cores, 2 cores thiab 4 cores ib hom fiber ntau optic cable.Feem ntau, ib qho tseem ceeb yog siv rau kev xa cov ntaub ntawv hauv tsev, thiab 2 cores yog siv rau hauv xov tooj cua, TV, cable TV thiab broadband.
poob cable optical fibers feem ntau suav nrog G657A2 optical fibers, G657A1 optical fibers, thiab G652D optical fibers.Muaj ob hom kev txhawb nqa hauv nruab nrab, cov khoom siv hlau thiab cov khoom tsis yog hlau FRP.Cov khoom siv hlau muaj xws li ① phosphating steel hlau ② tooj liab plated steel hlau ③ galvanized steel hlau ④ glued steel hlau (xws li phosphating steel hlau thiab galvanized steel hlau nrog kua nplaum).Non-metallic reinforcements muaj xws li ①GFRP②KFRP③QFRP.
Lub sheath ntawm qhov poob cable feem ntau yog dawb, dub, thiab grey.Dawb yog feem ntau siv sab hauv tsev, thiab dub yog siv sab nraum zoov, uas yog UV-resistant thiab rain-resistant.Cov ntaub ntawv sheath muaj xws li PVC polyvinyl chloride thiab LSZH uas tsis muaj pa taws 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, ib leeg ntsug combustion nplaim retardant, thiab nras nplaim retardant.
Sab nraum zoov optical cable ncua kev kawm ntawv feem ntau tuaj yeem txhawb nqa tus kheej 30-50 meters.Phosphating steel hlau txais 0.8-1.0MM, galvanized steel hlau, glued steel hlau.
Cov yam ntxwv ntawm kev poob cable: tshwj xeeb khoov-resistant optical fiber, muab bandwidth loj dua thiab txhim kho kev sib txuas lus network;ob qho tib si FRP lossis hlau reinforcements ua rau cov khoom siv kho qhov muag muaj qhov ua tau zoo compressive 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 kev twb kev txuas, yooj yim installation thiab txij nkawm;Tsis tshua muaj pa taws halogen dawb nplaim hluav taws kub retardant polyethylene sheath los yog nplaim hluav taws retardant PVC sheath, ib puag ncig tiv thaiv.Nws tuaj yeem ua ke nrog ntau yam kev sib txuas ntawm cov teb thiab tuaj yeem raug txiav tawm.
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 npauj npaim, nws tseem hu ua npauj npaim cable, Daim duab 8 cable.Cov khoom siv yog siv rau hauv: siv rau hauv tsev thaiv, ncaj qha cable siv los ntawm cov neeg siv kawg;siv los qhia cov kab hluav taws xob kho qhov muag hauv cov tsev;siv rau sab hauv tsev ntawm cov neeg siv hauv FTTH.
