Lo lus nug yog tsis yog "uas teev zoo dua" tab sis "uas teev kev lag luam rau koj cov kev lag luam thiab kev pabcuam qib."
Yuav ua li cas koj thiaj paub thaum nws yog lub sij hawm los hloov kho los ntawm gps - pon?
Saib rau peb qhov ntsuas: (1) Yav tsaus ntuj cov lus tsis txaus siab vim GBPS sib tw tsis muaj teeb meem ntau dua li 5}} pon {{9} Pon ortizes Tshaj li 7 {- 10 xyoo). Yog tias koj tsim cov nroj tsuag fiber ntau, tso cov xgs-pon tam sim ntawd-tus nqi tshaj tawm hauv Gonpon tau tso qis dua 15%. Yog tias koj tswj cov gading uas twb muaj lawm, tsuas yog hloov kho thaum qhov xav tau tiag tiag lossis kev sib tw siab siab yuam nws.
Tuaj yeem faib cov cuab yeej fiber ntau tiag tiag rau ntau txhiab tus neeg tau txais kev pab?

Kev txiav txim siab archecture txiav txim siab
Cov lus nug "tuaj yeem FTTX Network architecture" tam sim no daws mus rau hauv kev txiav txim siab ua tau raws li koj cov kev txwv tshwj xeeb.
Yog tias koj yog neeg ua haujlwm npaj ua haujlwm xa:
Koj peb qhov kev txiav txim siab ua ntsuas yog:
Bandwidth ua tswv yim: Tso cov xgs - pon nrog 1:32 cais yog tias pabcuam hauv nroog loj uas muaj peev xwm xav tau. Tso cov qog nrog 1:64 splits rau tus nqi {}} Rollurban rollouts qhov twg 100 mbps ib tug neeg sau npe tau ua raws li kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau kev thov rau5+ xyoo.

Kev sib cais Architecture Xaiv: Siv Centralized Splits (FDH - Raws li cov cheeb tsam uas muaj ntau dua lossis sib npaug ntawm 40% ({} Cov tsev ib square mais). Siv faib faib rau cov neeg nyob deb nroog, phased xa cov neeg uas yuav tsis meej pem thiab ncav cuag cov tsev kev tsis sib haum xeeb yog qhov tseem ceeb. Kev xaiv architecture yog reversible tab sis kim}}}}} Xaiv raws li muaj tseeb tau txais} tus nqi projections, tsis yog kev ua tau zoo.
Kev Ua Haujlwm Infrastructure Peev: Siv FMSOR, cov cuab yeej tsim qauv tsim qauv, thiab cov txheej txheem teeb tsa txheej txheem ua ntej mus txog 3,000 subscribers. Yog lawm, tus nqi no $ 300K - $ 1m rau mid- kev ua haujlwm. Tab sis lwm txoj kev muaj kev ntxhov siab ntawm 5, {{}}}}} $ 3 lub hlis ntawm kev ua haujlwm thaum siv sijhawm.

Yog tias koj tau ntsuas FTTX network architecture rau kev lag luam lossis loj campus:
Xav txog seb Pon cov qauv sib koom ua ke rau koj cov ntaub ntawv siv. Cov kev lag luam uas muaj kev nkag siab, siab - kev siv cov} Kev kho mob, feem ntau tau txais txiaj ntsig zoo dua. Ntau - Cov tuam tsev xauj tsev thiab cov chaw pw hav zoov uas muaj cov qauv sib txawv
Cov thev naus laus zis tau matured dhau cov lus nug txog kev muaj peev xwm yooj yim. Niaj hnub nimno FTTX network architecture, kom tsim nyog tsim nrog bandwid
