Taw qhia
Raws li thev naus laus zis txuas ntxiv mus, txoj hauv kev uas peb nkag mus hauv is taws nem tau hloov pauv loj heev. Ib qho kev nce qib no yog kev siv FTTH kab. Tab sis qhov tseeb yog FTTH kab, thiab nws txhais li cas? Hauv tsab xov xwm no, peb yuav tshawb txog lub ntsiab lus ntawm FTTH kab, nws ua haujlwm li cas, nws qhov zoo, qhov tsis zoo, thiab ntau ntxiv.
FTTH Kab yog dab tsi?
FTTH sawv cev rau "Fiber to the Home". Nws yog ib qho kev siv tshuab uas tso cai rau kev teeb tsa ntawm fiber ntau optic cables ncaj qha rau hauv ib tus neeg lub tsev, yog li muab kev siv internet ceev ceev ncaj qha rau cov neeg siv kawg. Qhov tseem ceeb, FTTH kab yog qhov kev sib txuas uas tso cai rau lub network fiber ntau kom ncav cuag qhov chaw tshwj xeeb.
FTTH Ua Haujlwm li cas?
FTTH kev teeb tsa xav tau cov fiber ntau optic cables yuav tsum tau khiav ntawm lub tuam txhab kev sib txuas lus qhov ze tshaj plaws rau cov neeg siv khoom hauv tsev. Cov cables no yog nyias nyias, hloov tau cov iav fibers, muaj cov tub ntxhais, uas nqa cov ntaub ntawv, thiab ib txheej cladding, uas tiv thaiv cov tub ntxhais los ntawm kev puas tsuaj. Nyob ntawm qhov chaw thiab tus neeg zov me nyuam, txoj kev teeb tsa yuav txawv. Qee tus neeg muab kev pabcuam yuav txhim kho cov kab hauv av, thaum lwm tus siv cov kab hluav taws xob overhead.
Thaum cov fiber ntau optic cables tau teeb tsa, lawv txuas mus rau lub modem tshwj xeeb, hu ua Optical Network Terminal (ONT). Lub davhlau ya nyob twg no yog lub luag haujlwm rau kev hloov cov teeb liab teeb uas taug kev los ntawm fiber ntau rau hauv cov teeb liab hluav taws xob uas tuaj yeem siv los ntawm cov neeg siv khoom siv.
Qhov zoo ntawm FTTH Kab
1. High-Speed Internet Access - Qhov zoo tshaj plaws ntawm FTTH kab yog qhov tshwj xeeb hauv internet ceev nws muab. FTTH thev naus laus zis muab qhov nrawm tshaj plaws hauv Is Taws Nem muaj, nrog qee cov chaw muab kev pabcuam nrawm dua 1 Gbps. Qhov no yog vim hais tias fiber ntau optic cables muaj peev xwm thauj cov ntaub ntawv loj nyob rau hauv qhov ntev ntawm kev kub ceev.
2. Txhim kho kev ntseeg siab - FTTH kab tsis cuam tshuam los ntawm qee qhov teeb meem uas tshwm sim nrog kev sib txuas ntawm cable lossis DSL hauv internet, xws li teeb liab degradation, huab cua cuam tshuam, lossis suab nrov. Qhov no ua rau FTTH kev sib txuas ua tau zoo kawg nkaus, nrog lub sijhawm poob qis heev.
3. Flexibility - Nrog FTTH kab, cov neeg siv khoom tuaj yeem tshaj tawm cov yeeb yaj kiab zoo, ua si hauv online, thiab ntau ntxiv, ib txhij nrog lwm cov khoom siv, tsis muaj kev lag luam lossis teeb meem kev sib txuas qeeb.
Qhov tsis zoo ntawm FTTH Kab
1. Cov Nqi Them Pib Pib - Kev teeb tsa ntawm FTTH kab tuaj yeem kim heev rau cov chaw muab kev pabcuam hauv internet. Nyob ntawm qhov chaw, khiav fiber ntau-optic cables rau ib tus neeg lub tsev tuaj yeem nyuaj thiab raug nqi, uas yuav ua rau cov nqi siab dua rau cov neeg siv khoom.
2. Tsis Muaj Kev Pabcuam - Txawm tias muaj txiaj ntsig ntau ntawm FTTH thev naus laus zis, tsis yog txhua qhov chaw muaj kev nkag mus rau nws, vim nws tseem tsis tau muaj kev siv tshuab tag nrho.
3. Cov teeb meem kev sib raug zoo - FTTH kab yuav xav tau ib lub modem lossis router tshwj xeeb txhawm rau ua kom muaj kev sib raug zoo tag nrho, thiab tsis yog txhua yam khoom siv yuav ua tau nrog cov kev sib txuas no.
Xaus
FTTH thev naus laus zis yog qhov kev nce qib tseem ceeb hauv txoj hauv kev uas peb nkag mus hauv Is Taws Nem. Nrog nws cov peev xwm siab ceev, yoog raws, thiab kev ntseeg siab, nws tsis yog qhov xav tsis thoob tias FTTH kab tau nrov zuj zus. Txawm hais tias muaj qee tus nqi pib thiab cov teeb meem sib raug zoo, cov txiaj ntsig tau pom tseeb, ua rau nws hloov pauv kev ua si hauv ntiaj teb ntawm kev sib txuas hauv internet. Txawm hais tias koj yog tus neeg siv internet hnyav lossis tsuas yog xav tau kev sib txuas txhim khu kev qha, FTTH kab yog qhov kev xaiv zoo heev.
