Puas yog FTTB tseem yog qhov kev xaiv zoo rau cov tsev tsev laus?

Nws tuaj yeem ua tau, yog tias lub tsev nyob hauv cov xaim hluav taws xob yog qhov tsim nyog. Cov tsev nrog Cat5e lossis Cat6 Ethernet tuaj yeem xa cov kev pabcuam gigabit los ntawm FTTB. Cov vaj tse uas tsuas yog cov xov tooj qub qub lossis cov coaxial cabling puas yuav pom cov txiaj ntsig tsis muaj zog.

FTTB puas tuaj yeem hloov mus rau FTTH tom qab?

Yog lawm, tab sis qhov nyuaj yog nyob ntawm qhov chaw muaj nyob, chav xov tooj muaj peev xwm, thiab seb puas muaj fiber ntau tuaj yeem xa mus rau txhua chav tsev yam tsis muaj kev tsim kho loj. Tus nqi tshaj - txoj hauv kev ua tau zoo yog los npaj rau yav tom ntej FTTH peev xwm thaum lub sij hawm pib FTTB xa tawm los ntawm kev qhia txog cov kav dej loj thiab qhov chaw seem.

Qhov twg zoo dua rau kev txhim kho vaj tse tshiab?

FTTH yuav luag txhua qhov kev xaiv zoo dua rau kev tsim kho tshiab. Txij li cov txheej txheem thiab cov khoom siv tau raug teeb tsa los ntawm kos, khiav fiber ntau rau txhua lub tsev ntxiv cov nqi ntxiv me ntsis thiab tsim kom muaj kev lag luam ntau dua, yav tom ntej -cov khoom npaj.

Puas yog FTTH ib txwm txhais tau tias Internet ceev dua?

FTTH tsis cia li txhais tau tias nrawm tshaj tawm, tab sis nws txhais tau tias kev ua tau zoo sib xws, qis dua latency, thiab zoo dua symmetrical bandwidth. Cov qib ceev tiag tiag nyob ntawm qhov kev pab cuam thiab PON tus qauv siv (GPON, XGS-PON, thiab lwm yam), tab sis txoj kev fiber ntau nws tus kheej tsis yog lub hauv paus.

Puas yog FTTB txaus rau cov tsev ua haujlwm?

Nws nyob ntawm tus neeg xauj tsev xav tau. Rau kev siv hauv chaw ua haujlwm, FTTB nrog Cat6 sab hauv cabling tuaj yeem tsim nyog. Rau cov neeg xauj tsev khiav bandwidth-kev ua haujlwm hnyav - loj- teev video conferencing, huab- hnyav ua haujlwm, lossis cov ntaub ntawv-center-xws li kev sib txuas - FTTH muab lub neej yav tom ntej ntau dua thiab ntau dua - pov thawj qab nthab.

Kuv tuaj yeem qhia tau li cas tias kuv tus kws kho mob muab FTTH lossis tsuas yog fiber ntau rau lub tsev?

Nug seb cov fiber ntau puas nyob hauv koj chav tsev lossis ntawm qhov chaw sib koom hauv lub tsev. Yog tias muaj cov khoom siv ONT hauv koj thaj chaw nrog cov khoom siv fiber ntau, koj muaj FTTH. Yog tias koj qhov kev sib txuas los ntawm Ethernet, xov tooj, lossis coaxial qhov hluav taws xob, cov fiber ntau yuav nres ntawm lub tsev.

Cov neeg tsim khoom yuav tsum xav txog dab tsi ua ntej xaiv FTTH lossis FTTB?

Cov yam tseem ceeb yog lub tsev (tsim tshiab vs. retrofit), cov kab mob sab hauv, muaj txoj hauv kev thiab cov kav dej, qhov xav tau ntawm cov neeg xauj tsev xav tau, qhov peev txheej, thiab seb puas yuav hloov mus rau FTTH yog ib feem ntawm txoj kev npaj. Ib daim ntawv ntsuam xyuas ua ntej - xa mus rau qhov chaw xa tawm yuav tsum qhia qhov kev txiav txim siab ua ntej ib qho kev teeb tsa tau teev tseg.
