FTTH kab

FTTH Drop cable yog dab tsi?
 

 

Lub sheathed optical cable feem ntau yog ib leeg-ntxhais lossis dual-core qauv, thiab tuaj yeem ua rau hauv plaub-core qauv. Ntu ntoo khaub lig yog 8-zoo li tus, thiab lub zog yog nyob rau hauv nruab nrab ntawm ob lub voj voog. Nws tuaj yeem ua los ntawm cov hlau lossis cov hlau tsis yog hlau, thiab cov khoom siv kho qhov muag yog nyob ntawm qhov chaw geometric ntawm 8. Cov fiber ntau hauv cov sheathed optical cable txais G.657 me me dabtsi yog khoov vojvoog optical fiber, uas tuaj yeem nteg nrog ib tug dabtsi yog khoov vojvoog ntawm 20 hli, thiab yog haum rau nkag mus rau hauv lub tsev nyob rau hauv daim ntawv ntawm pipelines los yog qhib xov hlau nyob rau hauv lub tsev. Drop cable feem ntau hu ua indoor suspended wiring cable.

Nrog rau kev lag luam hauv kev lag luam fiber ntau optic uas qhia txog kev txhim kho zoo, kev siv fiber ntau optic tau dhau los ua qhov chaw kub hauv kev sib txuas lus kho qhov muag. Nyob rau hauv qhov project fiber optic access, sab hauv tsev thaiv cov neeg siv yog qhov nyuaj tshaj plaws txuas. Kev khoov kev ua tau zoo thiab tensile lub zog ntawm cov pa hauv tsev kho qhov muag cables tsis tuaj yeem ua tau raws li qhov xav tau ntawm FTTH (fiber rau hauv tsev) hauv tsev thaiv.
Kev nkag mus rau lub network phaj-zoo li tus taw qhia cable (rau hauv tsev xaim) yog muab cov chaw sib txuas lus kho qhov muag (optical fiber) nyob rau hauv nruab nrab, thiab muab ob qho tib si uas tsis yog-metallic reinforcements (FRP) los yog hlau reinforcement Cheebtsam ntawm ob sab. Thaum kawg, cov xim dub lossis xim polyvinyl chloride (PVC) lossis cov khoom siv tsis muaj pa taws halogen (LSZH, cov pa luam yeeb tsawg, tsis muaj halogen, nplaim hluav taws xob) sheath yog extruded.

Cov neeg siv hluav taws xob hauv tsev

Hauv FTTH cov haujlwm, cov neeg siv hluav taws xob sab hauv tsev yog qhov txuas nyuaj tshaj plaws, thiab muaj ntau yam los xav txog. Nws yog ib qho tsim nyog los xyuas kom meej qhov kev nyab xeeb ntawm txoj kab, coj mus rau hauv tus account qhov kev zoo nkauj ntawm sab hauv, thiab pab txhawb kev tsim kho. Cov kab ke ib txwm nyob hauv tsev kho qhov muag tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev xaim hauv tsev hauv FTTH tam sim no. Raws li kev hloov pauv rau cov kab hluav taws xob sab hauv tsev kho qhov muag, Weipuxun's sheathed optical cable tuaj yeem hloov mus rau feem ntau cov kab hluav taws xob sab hauv tsev. Piv txwv li, nws tuaj yeem tig nrog lub vojvoog dabtsi yog khoov ntawm 20mm, tuaj yeem dais sab siab ntawm cov neeg taug kev ntawm cov kab hluav taws xob kho qhov muag, thiab qhov nro tshwm sim los ntawm kev rub thaum tsim kho. Nyob rau tib lub sijhawm, nrog ntau yam ntawm cov khoom sib txuas ntawm qhov chaw, kev txiav tawm ntawm qhov chaw thiab docking tuaj yeem ua tiav hauv lub sijhawm luv tshaj plaws. Yog li ntawd, Weipuxun's sheathed optical cable yog qhov kev xaiv zoo tshaj plaws rau FTTH hauv tsev thaiv.

Kev Txhawb Nqa Tus Kheej Cov Khoom Siv Hluav Taws Xob Hauv Tsev

Qhov kev txhawb nqa tus kheej "8" xov hlau kho qhov muag muaj cov hlau raug tshem tawm, yog li nws muaj zog tensile tsis kam thiab tuaj yeem tiv taus qhov ntev ntawm 50 meters. Cov kab hluav taws xob kho qhov muag tau muab tso rau sab nraum zoov hauv ib qho nyiaj siv ua haujlwm. Ua ntej nkag mus rau hauv lub tsev, chav tsev hlau raug txiav tawm thiab tsau rau ntawm qhov chaw tshwj xeeb. Qhov seem kho qhov muag cable yog stripped ntawm cov hlau ncua kev kawm ntawv thiab nkag mus rau hauv chav tsev siv ib tug sheathed optical cable.

 

Pipeline Tsev Siv Hluav Taws Xob

Vim hais tias lub raj xa hluav taws xob kho qhov muag cable nyuaj dua li cov sheathed kho qhov muag cable thiab muaj zog tensile ntau dua, thiab cov khoom siv kho qhov muag muaj cov khoom thaiv dej, uas tuaj yeem txo cov nag los nag sab nraum zoov, nws yog qhov tsim nyog rau kev tso dej tawm sab nraum zoov ntev. Weipson pipeline mapping optical cable txais cov qauv uas tsis yog xim hlau, yog li zam qhov kev taw qhia ntawm xob laim rau hauv chav. Tom qab cov kab hluav taws xob kho qhov muag nkag mus rau hauv tsev, nws cov sheath sab nrauv, cov khoom siv dej thaiv thiab cov cuab yeej siv tau raug tshem tawm, thiab nruab nrab ntawm daim tawv nqaij-hlau kho qhov muag cable yog siv ncaj qha rau cov xaim hluav taws xob sab hauv tsev, tau txais txhua qhov zoo ntawm cov tawv nqaij-hlau optical cable hauv tsev thaiv, thaum txo cov kev sib txuas ntawm sab nraum zoov thiab sab hauv tsev kho qhov muag cable txuas.

 

FTTH Drop Cable Structure

Ordinary drop cable muaj tus qauv 8-zoo li tus qauv; ob qho tib si txhawb nqa cores, nrog optical fiber nyob nruab nrab; kev txhawb nqa tus kheej poob cable ntxiv cov tuab steel hlau ncua kev kawm ntawv rau cov qauv ntawm kev poob cable; Feem ntau hais lus, kev txhawb nqa tus kheej poob cable tsuas muaj ib qho ntxiv steel hlau, thiab tsis muaj dab tsi hloov pauv; cov qauv ntawm hom kab no txawv rau txhua tus neeg tsim khoom. Tab sis feem ntau, lawv tsis yog hlau reinforcing cores. Coj npauj npaim poob cable ua piv txwv. Tus ntoo khaub lig zoo li npauj npaim, thiaj li hu ua. Ob sab yog cov xaim xaim, sab hauv yog cov tswv cuab txhawb zog, thiab nruab nrab yog cov khoom siv kho qhov muag.
