Dab tsi yog Fiber Drop Cable?
Lub fiber nco cable yog qhov chaw sib txuas lus kho qhov muag (optical fiber) nyob rau hauv qhov chaw, ob qho tib si tsis yog hlau qhov cuab lub zog (FRP) lossis cov tswv cuab hlau txhawb nqa tau muab tso rau ntawm ob sab, ntxiv rau cov xim dub lossis xim polyvinyl chloride (PVC) lossis cov pa taws tsawg halogen. -dawb khoom (LSZH), Tsawg-tsim pa luam yeeb, halogen-dawb, nplaim-retardant) sheath.Vim nws cov duab npauj npaim, nws tseem hu ua npauj npaim kho qhov muag cable thiab daim duab 8 optical cable.
Qauv thiab Hom Fiber Drop Cable:
Lub fiber nco cable kuj muab faib ua sab hauv thiab sab nraum zoov.Qhov zoo tib yam fiber ntau poob cable muaj tus qauv duab-yim qauv;ob qho tib si lub zog cov tswv cuab, qhov nruab nrab ntawm cov khoom siv kho qhov muag, feem ntau yog siv sab hauv tsev;tus kheej txhawb nqa fiber ntau poob cable feem ntau yog siv sab nraum zoov, nyob rau hauv cov fiber ntau poob cable tuab steel hlau ncua kev kawm ntawv hlau yog ntxiv rau cov qauv.
Strength Member, fiber ntau drop cable nrog hlau lub zog cov tswv cuab tuaj yeem ua tiav lub zog tensile ntau dua thiab tsim nyog rau qhov ntev nyob sab hauv tsev kab rov tav kab lossis luv-nyob sab hauv tsev ntsug thaiv.Cov hlau muaj zog cov tswv cuab fiber ntau poob cable tsis tau ntxiv nrog cov pa phosphating steel hlau, tab sis nrog cov khoom siv tshwj xeeb tooj liab-clad steel hlau, uas tuaj yeem zam kev puas tsuaj rau cov khoom siv kho qhov muag los ntawm lub caij nplooj ntoos hlav thiab winding los ntawm phosphating steel hlau hauv kev tsim kho engineering.Lub zog tsis yog xim hlau cov tswv cuab fiber ntau poob cable siv FRP raws li cov khoom siv ntxiv, uas tau muab faib ua ob hom kfrp thiab gfrp.Kfrp yog softer thiab ntau ductile, sib dua thiab kim dua.Nws tuaj yeem paub txhua yam khoom siv hauv tsev tsis yog xim hlau thiab muaj kev tiv thaiv zoo tshaj plaws.Haum rau kev taw qhia los ntawm sab nraum zoov mus rau sab hauv tsev.
Outer Jacket, PVC lossis LSZH cov khoom siv feem ntau yog siv rau lub tsho sab nrauv ntawm fiber ntau poob cable.Cov nplaim retardant kev ua tau zoo ntawm LSZH cov khoom yog siab dua li cov khoom siv PVC.Nyob rau tib lub sijhawm, kev siv cov khoom siv LSZH dub tuaj yeem thaiv kev yaig ultraviolet thiab tiv thaiv kev tawg, thiab tsim nyog rau kev taw qhia ntawm sab nraum zoov mus rau sab hauv.
Optical Fiber Hom, hom fiber ntau kho qhov muag ntawm fiber ntau poob cable yog G.652.D, G.657.A1, G, 657.A2.Cov khoom siv kho qhov muag hauv cov fiber ntau poob cable siv G.657 me me dabtsi yog khoov vojvoog fiber ntau, uas tuaj yeem khoov ntawm 20 hli.Radius nteg yog tsim rau nkag mus rau hauv lub tsev nyob rau hauv lub tsev los ntawm txoj kev ntawm pipeline los yog kaj kab.G.652D ib hom fiber ntau yog ib hom fiber ntau nrog cov ntsuas nruj tshaj plaws ntawm txhua qib G.652 thiab rov qab ua tau tiav.Nws yog structurally tib yam li zoo tib yam G.652 fiber ntau thiab yog tam sim no tus tshaj plaws siv nyob rau hauv lub nroog cheeb tsam tes hauj lwm.Non-dispersion hloov ib hom fiber ntau.
Feature ntawm Fiber Drop Cable:
1. Lub teeb yuag thiab me me txoj kab uas hla, nplaim retardant, yooj yim rau kev sib cais, yooj yooj yim, kuj zoo bending kuj thiab yooj yim kho;
2. Ob qho tib si FRP lossis cov khoom siv hlau muaj zog tuaj yeem muab cov compression zoo thiab tiv thaiv cov fiber ntau optical;
3. Cov qauv yooj yim, lub teeb yuag thiab muaj zog practicability;
4. Qhov sib txawv groove tsim, yooj yim tev tawm, yooj yim rau kev txuas, yooj yim installation thiab txij nkawm;
5. Tsis tshua muaj pa taws halogen-dawb nplaim-retardant polyethylene sheath los yog ib puag ncig tiv thaiv PVC sheath.
Daim ntawv thov ntawm Fiber Drop Cable:
1.Cov neeg siv hluav taws xob sab hauv tsev
Cov kab hluav taws xob sab hauv tsev muaj nyob rau hauv cov lus qhia tshwj xeeb xws li 1 cores, 2 cores, 3 cores, 4 cores, thiab lwm yam. Ib leeg tub ntxhais cables yuav tsum siv rau cov neeg siv hauv tsev kom nkag tau npauj npaim kho qhov muag cables;rau cov neeg siv kev lag luam kom nkag mus rau npauj npaim kho qhov muag cables, 2--4 core cables tsim.Muaj ob hom npauj npaim-zoo li lub tsev kho qhov muag cables: non-metallic ntxiv dag zog rau cov tswv cuab thiab cov tswv cuab hlau.Ua tib zoo saib xyuas cov xwm txheej ntawm kev tiv thaiv xob laim thiab muaj zog hluav taws xob cuam tshuam, uas tsis yog xim hlau ntxiv dag zog rau cov tswv cuab npauj npaim optical cables yuav tsum tau siv sab hauv tsev.
2.Vertical thiab kab rov tav thaiv hauv lub tsev
Ib yam li cov kab hluav taws xob sab hauv ntawm tus neeg siv, txoj kab kab rov tav tsis xav tau ntau ntawm cov kab hluav taws xob kho qhov muag, tab sis txoj kab ntsug yuav tsum xav tau cov kab hluav taws xob kho qhov muag kom muaj qee lub zog ntawm tensile kev ua tau zoo, yog li peb yuav tsum xav txog qhov tensile kev ua tau zoo ntawm fiber ntau poob cable. thaum yuav khoom
3.Kev txhawb nqa nws tus kheej aerial-tsev thaiv
Kev txhawb nqa tus kheej "8" xov hlau kho qhov muag ntxiv cov hlau dai hlau hauv lub hauv paus ntawm fiber ntau poob cable, yog li nws muaj zog tensile ntau dua, tuaj yeem siv rau saum taub hau nteg, thiab tsim nyog rau sab nraum zoov nyiaj siv ua hluav taws xob rau sab hauv tsev thaiv ib puag ncig. .Cov kab hluav taws xob kho qhov muag tau muab tso rau hauv ib qho nyiaj siv ua haujlwm sab nraum zoov, lub tsev hlau dai hlau yog txiav tawm ua ntej nkag mus rau hauv lub tsev, thiab tsau rau ntawm ib qho tshwj xeeb tuav, thiab cov khoom siv kho qhov muag ntxiv yog stripped ntawm cov hlau dai hlau thiab nkag mus rau hauv chav nrog ib tug fiber poob cable.
4. Cov kav dej hauv tsev
Cov yeeb nkab-mapping optical cables thiab kev txhawb nqa tus kheej "8" thaiv kab hluav taws xob yog ob qho tib si sab hauv tsev thiab sab nraum zoov kev sib txuas kho qhov muag, uas tuaj yeem hloov kho rau ob qho tib si sab hauv tsev thiab sab nraum zoov, thiab tsim nyog rau FTTH kev taw qhia los ntawm sab nraum zoov mus rau sab hauv tsev.Vim yog qhov sib ntxiv ntawm cov ntaub thaiv sab nrauv, cov khoom siv ntxiv thiab cov khoom thaiv dej los ntawm lub hauv paus ntawm fiber ntau poob cable, cov yeeb nkab-mapping optical cable tau txhim kho hardness thiab waterproof kev ua tau zoo, thiab yog tsim rau sab nraum zoov yeeb nkab tso.
