FTTH Fiber Optic Cable rau Cov Tsev Neeg
Fiber rau lub tsev (FTTH), tseem hu ua "fiber ntau rau qhov chaw" (FTTP), yog qhov kev siv thiab siv fiber ntau ntawm cov cuab yeej xws li tsev neeg ib leeg (SFUs), cov chaw ua haujlwm sib ntau (MDUs), thiab cov lag luam los muab kev pabcuam kom muaj kev lag luam hauv high-speed. FTTH network yog yooj yim los tswj thiab muab kev pab cuam ntau tshaj 100 zaus ntau dua li cov coaxial, wireless, lossis tooj liab. Nws muaj peev xwm tsis muaj peev xwm nqa xov tooj, Internet, digital TV thiab lwm yam kev pabcuam rau cov neeg muaj npe-nrog kev ua haujlwm zoo thiab kev cia siab!
Fiber Optic Cable tau muab pov thawj kom xa cov ntaub ntawv khaws tseg, suab thiab yees duab rau lub tsev kom muaj txiaj ntsig zoo thiab muaj kev ruaj ntseg tiv thaiv kab lis kev cai copper mediums. Peb txhua tus paub txog qeeb qeeb qeeb, DSL tawm, thiab coax cable teeb meem (Broadband Cable TV). Thaum fiber optic yog deployed raws li qhov xaus mus xaus daws, tag nrho cov teeb meem qhov tau txais los ntawm kev siv tooj liab / coax raws li kev thauj cov tsev yuav kawg.
Cov kev xaiv rau FTth Cabling Solution
FTTH tes hauj lwm muab nruab rau hauv ntau qhov chaw uas muaj kev sab hauv sab hauv, sab nraum zoov, thiab kev hloov ntawm nruab nrab. Kom ua kom tiav cov kev xav tau ntawm cov chaw sib txawv, ntau hom fiber ntau fiber ntau cab tsim.
Sab Hauv Tsev Cables
FTTH nyob sab hauv tsev siv hauv tsev lossis tsev mus txuas rau FTTH neeg siv khoom kawg. Cov phom ntau yog feem ntau yog 1, 2 lossis 4 optical strands feem ntau nrog ob leeg tsis-hlau enhanced FRP / Hlau / KFRP uas muaj peev xwm muab tau yooj yim tensile zog thiab zoo tiv thaiv rau lateral crushing los tiv thaiv cov fiber ntau hauv. Tsis tas li ntawd, nws txoj hlua txheej tshooj dav dav nrog LSZH cov khoom uas muaj nplaim hluav taws-xim dawb lossis dawb. Qhov yooj yim yooj yim qauv ua nws zoo meej rau sab hauv cabling.
Daim duab 1: Tus qauv ntawm FTTH nyob sab hauv tsev
FTTH nyob sab hauv tsev cab no yog:
Cov khoom siv tshwj xeeb qis-khib nyiab loj tshaj plaws yog muaj kev sib khoo thiab kev sib txuas lus zoo heev. Ob leeg cov tswvcuab hauv lub cev muaj zog tuaj yeem tiv thaiv kev ua haujlwm zoo los tiv thaiv cov ciaj. Cov qauv yooj yim, lub cev nyhav thiab qhov ua siab loj. Kev tsim hluav taws xob tshiab, tsim tau yooj yim thiab lwj, simplig qhov kev teeb tsa thiab kev kho.
Tee Cable
FTTH nco kab txuas nrog Network Access Point (NAP) mus rau cov neeg siv khoom chaw. Tee cables yog tsim nrog cov cwj pwm xws li ua kom yooj yooj yim, hnyav dua, me me inch, yooj yim ntawm cov khoom siv fiber ntau thiab txiav. Lawv cov qauv raws li lawv cov kev ua haujlwm yog ua kom tau haujlwm nrog ntau yam kev siv FTTH. Tig cab yuav tsuas muaj 1 lossis 2 fibers rau qhov txuas hluav taws xob txuas thiab muaj peev xwm ntxiv fibers rau thaub qab los yog lwm yam teeb meem network. Qhov hom xov tooj cua no muaj tsawg dua ntawm cov neeg siv fiber ntau thiab muab qhov txuas nkaus rau tus neeg siv, tsis muaj ntau hom kev lag luam. Tig cab yuav muab faib ua 3 hom: ncaj nraim faus, tshuab fais fab cua tshuab thiab cua tshuab.
Xam 2: Tsim ntawm FTTH poob cable
FTTH poob cable yog qhia los ntawm:
Ntev thiab nplaim LSZH txoj hlua, hluav taws tsawg pes tsawg xaj halogen Tib tus hlau hlau raws li qhov ntxiv lub zog muaj peev xwm saib xyuas kev ua tau zoo ntawm tensile lub zog Ob tus neeg koom nrog FRP muaj zog kom cov neeg ua haujlwm zoo tiv thaiv electromagnetic thiab zuaj tawv nqaij Kev leb high speed optical nyob hauv tsev
Distribution Cable
Fiber tis cable yog zoo tagnrho rau cov ntawv thov ntxiv tib qho kev txiav tawm nrog ntau fibers. Nws muaj qhov nrig buffered tsim kom nws tau muab tso rau hauv lub tsev pob txha hauv tsev thiab qhov chaw sib txuas ntawm tsev kawm ntawv tsis muaj kev hloov ntawm cable ntau. Cov kev nrov nrov nrov yog tsim rau cov ntaub ntawv sab hauv / tawm sab nraud. Cov kab hluav taws xob muaj nyob rau hauv plenum, riser, unitised & non-unitized uas tsim kom muaj ntau yam kev sib txuas ntawm lub ntsiab. Lawv cov vojvoog me me thiab 900μm nruj-buffered fibers pub rau kev yoojyim thiab kev ua kom yooj yim.
Daim duab 3: Qauv ntawm FTTH tis cablexxx
FTTH faib tshuab cable yog qhia los ntawm:
900μm Tight Buffered Fibers: kev txiav tawm sai thiab tsis muaj zog Ib Leeg Cov Chav Ua Si: muab nyiaj txuag chaw & kev sib txuas yooj yim Tag Nrho-Dielectric Cov Qauv: tshem tawm qhov xav tau grounding Interlocking Armor: tshem tawm qhov kev xav tau rau conduit
Kev Ceeb Toom rau Kev Xaiv FTTH Fiber Optic Cable
Muaj ntau yam yuav tsum tau ua thaum txiav txim siab zaum kawg.
Fiber Hom Tawm Nruab Nrab
Yog tias lub network uas twb muaj lawm, cov khoom siv fiber ntau hauv qhov tshiab pawg yuav tsum sib haum nrog cov fais fab hauv lub network uas twb muaj lawm.
Lom Zem Lub Sij Hawm
FTTH networks yog tsim los nrog kev ua neej ntev txog 30 xyoo. Yog li ntawd nws yog qhov tseem ceeb heev uas cov kev nqis peev rau FTTH cov kev pabcuam yog tsim rau kev xav tau yav tom ntej. Cov kev hloov ntawm cov fiber ntau thaum lub sij hawm kev xav ntawm lub FTTH network tsis yog qhov tseeb.
Nruab Nruab
Tsis muaj teeb meem nyob sab hauv tsev los yog sab nraum zoov, muaj ib txwm muaj ntau qhov chaw uas koj lub laub yuav tsum tau ntsia. Piv txwv, nyob rau tej qhov chaw uas muaj fiber ntau uas koj lub cev yuav raug kev puas tsuaj, xws li qab daus los yog hauv qhov chaw sib koom nrog hluav taws xob los yog lwm qhov thaiv, koj xaiv tau lub xov tooj cua khawm yooj yim uas yooj yim thiab tuav tau yooj yim. Muaj ntau cov qhob uas yuav txiav txim xyuas seb hom fib fib ntau npaum li cas nyob rau ntau qhov chaw ntawm lub installation. Feem ntau, ib hom yuav tsis haum tag nrho.
Tom ntej kev sib tw thiab cov txiaj ntsig ntawm Fibre rau Lub Tsev (FTTH)
Rau cov neeg siv cov khoom siv hauv tsev tam sim no, FTTH yog ib lub qauv zoo heev. Thaum koj muaj video chats thiab sib tham nrog kev sib tham nrog tsev neeg thiab cov phooj ywg, hom kev sib txuas lus no tuaj yeem xa tawm ntau cov ntaub ntawv los ntawm cabling thiaj li los xyuas kom meej video sib tham, uas dhau los ua kom yooj yim thiab txhim khu kev qha.
Qee cov kws txawj taw qhia tias FTTH yog kev sib tham txog kev sib tham hauv kev sib tham hauv xov tooj hauv kaum xyoo. Raws li peb txhua tus paub, fiber ntau rau lub tsev yog ib qho kev sib koom ua ke uas tsis xav tau yam tsis muaj lub luag haujlwm, yog li tus nqi them nuj nqis ntawm lub network thiab kev txhim kho nws tau raug txo kom tsawg. Tab sis qhov no yog qhov tseem ceeb tshaj plaws rau cov tseem ceeb ntawm FTTH? Dab tsi yog qhov zoo ntawm nws?
Ua ntej, cov kab mob fiber ntau tsis muaj kev ruaj ntseg, vim hais tias lawv yuav tsis yooj yim corroded los ntawm xob laim los nag, los yog ua rau to. Vim nws txoj kev ruaj siab ruaj khov, optical fibers maj mam muab hloov tooj rau hauv kev sib koom tes network, txhawb kev tsim kho thiab kev kawm ntawm kev siv tshuab.
Secondly, nws yuav muab unlimited bandwidth. Nrog rau kev tsim cov tshuab, kev siv video, xws li video streaming, IPTV, zoo nkauj video conferencing, lub cuab yeej siv hluav taws xob, IP video tshawb xyuas, thiab kev ua si yog maj mus nyob hauv tib neeg lub neej txhua hnub, uas ua rau kev nthuav dav ntxiv ntawm tib neeg qhov kev thov rau bandwidth . Tam sim no, tsuas yog qhov kho qhov muag network thiaj li muaj kev lees paub.
Thirdly, FTTH network tsim kho tau cov txiaj ntsim zoo rau cov neeg tau txais kev pab. Raws li FTTH Council txheeb cais, FTTH network pab txhua tsev neeg nrog cov nyiaj tiag tiag ntawm kwv yees $ 5000. Tsis tas li, kev tsim kho ntawm FTTH lub network ua rau nws yooj yim dua rau cov neeg siv Internet, uas yog ze rau "lub ntiaj teb lub zos". Txawm nyob hauv thaj chaw deb zos, tib neeg kuj tuaj yeem ua cov neeg ua lag luam thoob ntiaj teb.
