Yuav ua li cas FTTH Broadband Ua Hauj Lwm?
Tshem tawm thiab xav li cas koj cov kev siv Internet tau hloov hlo hauv ob peb lub xyoos dhau los. Yog tias koj zoo li cov neeg feem coob, koj yuav ua tau, thiab tab tom nrhiav kom paub ntau ntxiv hauv online, xws li muaj kev tshaj lij tawm thiab upload thiab download tau cov duab thiab video.
Cov ntaub ntawv loj tshaj yog txav mus rau hauv cov cybererspace network hnub no, thiab cov kws txawj xav tias qhov kev sib txawv tsuas yog nce ntxiv. Nyob rau lub Ib Hlis 2008, txoj kev tshawb fawb los ntawm Discovery Lub Koom Haum yuav kwv yees tshiab technologies yuav tsav tsheb hauv Internet li ntawm 50 zaus nws cov nqi tam sim no hauv 10 lub xyoos tom ntej.
Lub siab rau kev txuas zoo dua yog ib qho ntawm cov laj thawj loj thiab cov neeg siv los saib nws cov khoom siv fiber ntau txuas mus rau kev sib txuas lus hauv tsev kom muaj kev sib raug zoo.
Kev sib txuas ntawm FTTH broadband, xa mus rau fiber ntau optic cables txuas rau txhua tus neeg thaj chaw. Cov kev kho mob raws li qhov kev kho mob tau muab cov ntaub ntawv xov tooj, xov tooj, video, cov ntaub ntawv, thiab lwm yam zoo dua, ntau dua li cov kab lis kev cai siv tooj liab rau cov qub nqi. FTTH thaj chaw nyob ntawm seb ob qho tib si nquag thiab nquag siv kho qhov muag ua haujlwm.
FTTH Fiber Cable txuas yog ib qhov tseeb ntawm ntau tshaj li 1 lab tus neeg tau txais kev pab nyob rau hauv Tebchaws Meskas, thiab ntau dua 6 lab Japanese thiab 10 lab thoob ntiajteb kom zoo siab rau nws cov txiaj ntsim, cov khoom siv broadband raws li cov ntawv xov xwm. Ntau tus neeg xav tias FTTH technology txuj ci kom twv qhov sib txuas sib txuas network yuav daws tau cov tsheb ciav hlau.
Ntau tshaj li 10 plhom lub tsev nyob thoob ntiaj teb twb muaj fiber ntau txuas rau tsev sib txuas rau hauv tsev vim tias cov tshuab tev-vaus muaj ntau yam zoo dua tam sim no cov technologies.
Qhov zoo ntawm FTTH broadband txuas yog dab tsi?
Ib qho tseem ceeb ntawm FTTH - tseem hu ua FTTH - kuj hu ua FTTP, rau "fiber ntau rau qhov chaw" broadband - yog qhov uas nws muab kev ceev ceev thiab kev muaj peev xwm tshaj li cov neeg sib tw ua ke, DSL lossis coaxial cable. Cov kws tshawb fawb hauv FTTH Council hais tias kev sib txuas ntawm fiber-to-the-home yog cov cuab yeej tsuas muaj kev sib koom tes txaus los tswj cov neeg tau txais kev pab nyob rau lub xyoo kaum ntab reliably and cost effective. Cov cuab yeej technology twb yog, pheej yig, raws li kev lag luam nyob thoob ntiaj teb pom tau tias yog nkag mus rau hauv lub lag luam li lawv xav tau ntawm kev xav tau.
Fibre muaj ib qho zoo siv qhab nia txuas nrog ntev ntev, ua rau "kev ruaj ntseg yav tom ntej," los yog tus nruab nrab nruab nrab uas yuav nyob rau qhov chaw ntev ntev tuaj.
Txawm li cas los xij, kev txhim kho cov nqi bandwidth thiab kev siv tshuab tam sim no. Raws li FTTH Council, cable tuam txhab tau siv $ 84 kuj rau kab tsev neeg kaum xyoo dhau los, tab sis nws tsis muaj nuj nqis hnub no cov nyiaj hauv cov tsev nrog FTTH technology.
FTTH yuav muaj peev xwm tswj tau txawm siv Internet tom ntej siv ib co kws tshaj li pom yav tom ntej. Cov technologies xws li 3D holographic high definition TV thiab kev ua si yuav muaj ib hnub ua txhua yam khoom txhua hnub ntawm cov tsev neeg thoob plaws lub ntiaj teb. FTTH yuav ua tau kwv yees kwv yees li 30-gigabyte ib-thib ob kev xav tau ntawm cov khoom siv no.
Ntaus Nrig thiab Kev Tiv Thaiv Kev Nyuaj Siab
Muaj ob qho tseem ceeb ntawm cov tshuab uas ua rau FTTH broadband txuas tau. Cov no yog cov nquag optical tes hauj lwm thiab cov chaw ua haujlwm kho qhov muag zoo. Txhua txoj kev muab cais cov ntaub ntawv thiab txoj kev rov mus rau qhov chaw zoo, thiab txhua tus muaj qhov zoo thiab qhov tsis zoo li piv rau lwm tus.
Lub tshuab kho qhov muag zoo siv hluav taws xob txuas hluav taws xob, xws li lub router los yog kev sib hloov aggregator, tswj cov teeb liab kev sib tsoo thiab cov kev taw qhia ncaj qha rau cov neeg siv khoom. Qhov kev hloov no qhib thiab kaw nyob rau ntau txoj hau kev los tswj cov khoom xa tuaj thiab ntsaws rau qhov chaw zoo. Nyob rau lub lag luam no, ib tus neeg tuaj yeem muaj kev sib tw ua fiber ntau rau nws lub tsev.
Lub tshuab ua kom dav hlau tsis zoo, ntawm qhov tod tes, tsis suav cov khoom siv hluav taws xob hloov hluav taws xob thiab es siv cov khoom siv kho qhov muag cais tawm thiab sau cov cim kev pom zoo thaum lawv tsiv los ntawm lub network. Ib txoj kev siv fais fab paj nruag uas sib koom siv fiber ntau optic strands rau feem ntawm lub network. Cov khoom siv tsim nyog yuav tsum tau nyob rau ntawm qhov chaw thiab txais qhov xaus ntawm lub teeb liab.
Ntaus Nrig thiab Kev Tiv Thaiv Kev Xiam Hloov ntawm qhov zoo thiab qhov tsis zoo
Cov kev sib tw kho qhov muag zoo, lossis PONs, muaj qee qhov kev zoo. Lawv ua hauj lwm zoo, tias txhua qhov fiber ntau optic tau pab tau rau 32 tus neeg siv. PONs muaj ib lub tsev tsis tshua muaj kev txhim kho rau cov koom tes khov kho nrog rau cov nqi tsawg zog. Vim hais tias muaj ob peb qho kev hloov los yog hluav taws xob, qhov tsawg dua uas tuaj yeem mus tsis tau lawm hauv PON.
Cov kev sib tw kho qhov muag pom zoo kuj muaj qee qhov tsis zoo. Lawv muaj tsawg dua li ntawm cov nquag siv fais fab, lub ntsiab lus yuav tsum yog thaj chaw ze rau ntawm qhov chaw ntawm cov ntaub ntawv. Cov PONs tseem ua rau kom tsis muaj kev sib cais tawm thaum lawv tshwm sim. Tsis tas li ntawd, vim hais tias qhov bandwidth hauv PON tsis muaj nplooj siab rau cov neeg tau txais kev pabcuam, cov ntaub ntawv sib kis ceev tuaj yeem qeeb thaum lub sijhawm pabcuam ncav sijhawm nyob rau hauv ib txoj haujlwm hu ua latency. Latency sai txo cov kev pab cuam xws li cov suab thiab video, uas xav tau tus nqi kom zoo kom muaj kev zoo.
Active nias tes hauj lwm muab qee yam zoo, zoo li. Lawv tso siab rau Ethernet cov cuab yeej ua haujlwm ua ke ntawm cov neeg muag khoom yooj yim. Cov neeg muaj npe xaiv tau xaiv kho vajtse uas xa cov ntaub ntawv xa mus rau qhov tsim nyog thiab nce raws li qhov lawv xav tau nce ntxiv yog tsis muaj kev tsim kho dua tshiab.
Active optics tes hauj lwm, tab sis, kuj muaj lawv qhov tsis zoo. Lawv xav kom muaj tsawg kawg yog ib qho hloov aggregator rau txhua 48 tus neeg siv. Vim tias nws yuav tsum tau muaj hwj chim, ib qho chaw kho qhov muag tau zoo tshaj yog qhov kev tiv thaiv tsis ua haujlwm zoo dua ib txoj kev kho qhov muag pom zoo .
