Dab tsi Yog Qhov Sib txawv ntawm Broadband Thiab Qhwv Broadband?
Tam sim no, lub network tau dhau los ua qhov tseem ceeb ntawm tib neeg lub neej. Nrog cov thev naus laus zis txuas ntxiv ntawm qhov thev naus laus zis, qhov nruab nrab siv los nthuav tawm cov cim network tau hloov los ntawm broadband zoo tib yam thaum pib mus rau fiber ntau qhov dav dav uas peb feem ntau tau hnov txog, tom qab ntawd fiber ntau-optic broadband thiab broadband zoo tib yam sib txawv li cas?
Optical fiber xa cov cim xa mus rau hauv daim ntawv ntawm cov hluav taws xob sib xws, thiab siv iav los yog plexiglass ua lub network xa xov nruab nrab. Nws yog cov kis tau nruab nrab, xws li sib ntswg, tuab cable, nyias cable, thiab lwm yam. Nws qhov kis tau nrawm dua nrawm dua li qhov nruab nrab, uas tuaj yeem ncav ntau dua gigabit ib ob. Piv txwv li, qhov dav dav dav ntawm optical fiber yuav ncav cuag 100M. Tooj liab tooj liab yog ib qho nyuaj mus cuag.
Qhov zoo dua ntawm fiber optic broadband cov lus dag hauv tus nqi qis ntawm cov khoom siv sib txuas xws li cov chaw hubs thiab Ethernet hloov. Cov neeg siv tsis tas yuav nruab ADSL modems. Nov yog cov peev txheej rau kev sib tw Ethernet thiab ADSL. Optical fiber broadband cov neeg siv tau tsawg dua peev thiab txo nqi tus nqi. ADSL nkag mus siv tau ntawm txoj kev siv broadband zoo tib yam siv cov xov tooj hauv zej zog hauv cheeb tsam thiab lub chav computer ntawm lub xov tooj sib txuas. Nws tsis tuaj yeem sib cais los ntawm cov xov tooj xov tooj thiab muaj feem cuam tshuam hauv thaj chaw. Nyob rau tib lub sijhawm, tus nqi xov tooj kuj nce cov nqi khoom.
ADSL muaj cov kev cai dav dav rau cov kab ua tau zoo. Thaum cov kab ua haujlwm tsis zoo, kev ruaj khov yuav cuam tshuam. Thaum qhov kis tau tus mob siab dua, qhov sib zog ntawm attenuation thiab crosstalk ntawm lub teeb liab yog ntau dua, thiab qee zaum lub network tus nqi poob thiab txiav tawm.Qhov fiber ntau-optic siv dav siv cov network sib txawv ntawm lub xov tooj network. Txoj kev hloov kho hluav taws xob thiab hloov chaw hauv lub zej zog, lub chaw hloov mus rau hauv cov chaw hauv zej zog thiab lub hauv paus chaw ua haujlwm hloov yog txuas nrog hluav taws xob. Lub network muaj qhov siab ruaj khov thiab kev ntseeg tau, tsis txhob hais txog lub luag haujlwm. teeb meem.
Lub caij tuaj txog ntawm lub khoos phis tawm kho qhov muag lub sijhawm tsis yog tsuas yog nce ntawm kev nkag mus hauv Internet tau ceev los ntawm kev nkag mus rau cov kho qhov muag, tab sis tseem ceeb tshaj, ntau cov ntaub ntawv thov kev pab cuam los ntawm cov khoos phis tawj fiber ntau. Txhawm rau teb rau kev siv ntawm lub teb chaws" Broadband China" lub tswv yim, Cov Xeev tam sim no tseem ua tiav npaj kev npaj rau" txhua qhov txuas network hauv nroog" ;. Thaum xyoo 2011, Tuam Txhab Tebchaws Suav Telecom tau ua tus thawjcoj hauv kev tshaj tawm" Broadband China · Optical Network City" dej num. Lub hom phiaj kawg yog los pab cov neeg siv kom ua tiav qhov kev thov rau" kev siv is taws nem siv Internet tau txhua lub sijhawm, nyob qhov twg" ;. Cia lub neej tiag ua tiav" kev ceev ntawm lub teeb" kev txhim kho.
