Yuav ua li cas FTTX hom sib txawv?
BellSouth tau siv $ 4 txhiab lab txwv FTTC ua ntej AT & T Scrapped tag nrho cov architecture hauv fttn thiab ftp. Qhov ntawd tsis yog cov xaiv tsa cov tswv yim - nws yog pov thawj tias FTTX hom tsis sib txuas lus. Qhov twg koj cov chaw lim dej ua haujlwm txiav txim siab txhua yam: koj ceev ceev, kev lag luam ceev, thiab koj tab tom ua haujlwm rau 2025 lossis anatolescence.
Kev lag luam siv "fiber ntau rau X" zoo li X tsis muaj teeb meem. Nws ua li. Ftth txiav ntawm koj phab ntsa muab cov kev pab cuam symmetrical gigit. FTTN nres peb ntu pov tseg kom tsis txhob thawb 50 MBPS los ntawm kev laus tooj liab. Ob qho tib si siv cov xas no optic cables. Ob leeg tau daim ntawv lo broadband. Tus neeg siv kev paub tsis tuaj yeem sib txawv.
FTTX architures faib ua ob pawg: FTTHT, FTTB / FTTB qhov chaw mus rau thaj chaw, thiab FTTC / FTTN qhov chaw tooj liab ua tiav cov ntu kawg. Qhov kev faib no tsis yog semantic - nws yog lub cev qhov kev ua lub cev uas txiav txim siab txawm tias tooj liab los yog tooj liab. Lub ntiaj teb kev ua lag luam thoob ntiaj teb Optical tau mus txog $ 15.54 Billion hauv 2032, tsav tsheb ntau los ntawm cov neeg ua haujlwm xaiv ntawm cov duab no.
Qhov deb ntawm Central chaw ua haujlwm rau koj lub cuab yeej teeb meem tsawg dua qhov kev ncua deb ntawm fiber ntau qhov kawg ntawm qhov kawg rau koj cov cuab yeej. Lub mais ntawm fiber ntau ua raws li kaum mais. Tab sis 100 meters ntawm tooj liab hauv fttc kev xa cov vstment ua rau vstl speeds kom poob los ntawm 80 MBPS kom cov qib tsis siv. Kev nkag siab FTTX Cov kev sib txawv txhais tau tias kev nkag siab uas pib teeb meem pib.
Qhov kev ua kom muaj kev sib tshuam uas txhais tau txhua lub architecture
FTH cov nqi ntau dua rau kev tso tawm tab sis tshem tawm cov tooj liab bumple tag nrho. Cov Fiber txog qhov chaw nyob ze ntawm thaj chaw nyob, xws li lub thawv nyob sab nraud ntawm lub tsev, nrog {{1} {2} {gbps ncaj qha los ntawm lub chaw haujlwm hauv nruab nrab. Txhua lub tsev tau txais fiber ntau. Qhov ntawd kim nyob rau hauv suburban sprawl, yig nyob rau hauv nroog nroog dense, thiab vim li cas yog kev xaiv architecture nyob ntawm cov neeg ua yeeb yam ntom.
FTTB ua hauj lwm nruab nrab. Cov kab txuas rau kho qhov muag ntawm chav sib txuas lus hauv tsev, nrog cov kws kho mob muaj kev sib txuas lus zoo rau cov chav tsev txuas mus rau txhua lub tsev. Multi - Nyob rau hauv cov lag luam ua qhov kev lag luam no ua rau 50 qhov chaw siv roj fiber ntau. Cov lag luam tawm: Cov neeg nyob hauv tsev sib koom tes sib txuas thiab tsis tuaj yeem tshaj tus tooj liab cov kev txwv rau qhov kawg ntev.
FTTC tso cov fiber ntau nyob hauv 300 metres ntawm thaj chaw. Txoj kev Txee nyob ze rau cov neeg siv dua FTTN, nyob rau hauv ntau yam rau high {2} bandy kab ethernet lossis cov hluav taws xob sib txuam, feem ntau yog muab txog 100 MBP. Qhov no yog Bellsouth txoj kev xaiv ua ntej kev lag luam ua tsis tiav. Cov nqi txee rau cov nqi qis dua hauv tsev, tab sis koj tseem tsis tau txwv los ntawm tooj liab qhov chaw nyob deb. Nyob 295 metres los ntawm lub txee? Koj tau txais kev ceev ceev. Ntawm 305 metres? Kev ua tau zoo tsis txaus ntseeg.
FTTN thawb fiber ntau qhov deb tsawg kawg, kev txiav tawm hauv txoj kev txee tej zaum yuav tooj los ntawm cov qhua tuaj noj mov, feem ntau siv los ua ib kauj ruam sib txawv mus rau tag nrho FTH. BellSouth Kev tau txais los ntawm AT & T TUCTC xa tawm, nrog yav tom ntej cov khoom xa tuaj raws li FTTN lossis FTTP, thiab cov FTTC, thiab cov ftt Cov qauv hloov uas hloov tau qhia koj tias cov neeg ua haujlwm tau kawm tias: Cov kws kos duab hybrid ua haujlwm kom txog thaum tus kws sau npe xav tau ntau dua tooj liab lub qab nthab.
Cov lej uas yeej muaj tseeb
Kev ntsuas ceev ceev kev dag ntxias. "Txog li 100 MBPS" FTTC suab tsim nyog kom txog thaum koj ua tau haujlwm tiag tiag. Kev muab kev teeb tsa kev sib txheeb ze rau cov neeg ua haujlwm txiav txim siab txiav txim seb cov ceev txhais tau tias. Siab - qhov chaw nyob hauv tsev nyob hauv lub khw li 300-meter meter. Kev xa tawm cov neeg xa khoom nrog cov neeg xa khoom tawg ntawm ntau qhov kev ncua deb? Cia siab tias kev tsis txaus siab.
Lub ntiaj teb fiber ntau rau hauv kev ua lag luam hauv tsev tau txog $ 56.03 lab daus las hauv 2024% COMPORTIONED FTH cov kev pabcuam FTH tshem tawm cov kev pabcuam nrawm. Passer optical networks faib cov cim piav qhia yam tsis muaj cov cuab yeej siv ntawm nruab nrab chaw ua haujlwm thiab cov neeg yuav khoom.

Phua sib piv txiav teeb meem - 1:32 split txhais tau tias koj koom nrog 31 lwm cov neeg tau txais. Thaum lub sij hawm Peak, kev sib cav tshwm sim tshwm sim ntawm cov laus gon. Newer xgs-Pon muab cov hau kev ntau dua. Koj tus kheej chaw nres nkoj nrawm yog nyob ntawm ob qho tib si pon thev naus laus zis thiab phua sib cais.
TIVISG Kos duab xaiv los ntawm kev ua lag luam kev ua lag luam
Verizon xyoo 2010 kev txiav txim siab rau cua mus rau Fios Expansion tsis yog kev ua hauj lwm tsis yog technical- nws yog kev muaj nyiaj txiag. Verizon tshaj tawm thaum Lub Peb Hlis 2010 lawv tau mloog zoo rau ua tiav cov chaw ua tiav tab sis tsis txhob cia cov chaw tshiab uas twb muaj lawm, xav tias FRTTH tseem Uneconomic tshaj thaj chaw pabcuam. Ntawd yog Adas Architecture Xaiv Zaj Lus Qhia: Technology Muaj peev xwm lees paub kev lag luam xa khoom.
Qhov $ 4 billion BellSouth FTTC sau - tawm cov lus qhia zoo sib xws. Ua haujlwm thev naus laus zis, loj xa tawm, ua tiav cov tswv yim tso pov tseg. Tsis yog vim FTTC ua tsis tiav cov txheej txheem tab sis vim tias tooj liab cov kev txwv tiv thaiv kev sib tw ib zaug sib txawv thaum cov neeg sib tw ua ke.
Kev txiav txim siab architecture tau ua rau niaj hnub no tsim Infrastructure kav 30+ xyoo. Fiber faus tam sim no cov ntawv thov tseem tsis tau xeeb menyuam. Tooj liab tso tam sim no Constrains kev ua tau zoo raws li 20 {{{{}}}}}}}} Tus x hauv FTTX tsis yog cov sib txawv-} nws yog qhov kev txiav txim siab txiav txim siab tias koj lub network teev nrog kev thov lossis mob siab rau nws.
