Kev siv tshuab fiber-to-the-home (FTTH) tau hloov pauv txoj kev uas peb nkag mus rau hauv internet, muab kev sib txuas sai dua thiab txhim khu kev qha dua li yav dhau los. Lub plawv ntawm cov thev naus laus zis no yog FTTH drop cable, uas yog ib qho tseem ceeb hauv kev xa cov internet ceev ceev rau cov tsev thiab cov lag luam. Hauv phau ntawv qhia no, peb yuav tshawb nrhiav txhua yam koj xav paub txog FTTH drop cables, txij li lawv txoj kev tsim kho thiab kev teeb tsa mus rau lawv cov txiaj ntsig thiab kev siv.
FTTH poob cable yog dab tsi?
FTTH poob cable, tseem hu ua fiber optic drop cable, yog ib lub fiber optic cable tshwj xeeb tsim los txuas cov optical network terminals (ONTs) rau cov neeg siv khoom hauv fiber-rau-lub-tsev networks. Nws yog qhov txuas kawg hauv FTTH network, xa cov kev pabcuam Internet ceev ceev, TV thiab xov tooj ncaj qha rau cov neeg siv kawg.
Kev tsim kho ntawm FTTH kev taw qhia optical cable
Feem ntau, cov cables FTTH muaj ib lub zog nruab nrab uas muaj fiber optics nyob ib puag ncig thiab ib lub plhaub tiv thaiv sab nraud. Lub zog nruab nrab muab lub zog tensile tsim nyog rau lub cable kom tiv taus kev teeb tsa thiab kev ntxhov siab ib puag ncig, thaum lub fiber optic nqa cov ntaub ntawv teeb liab los ntawm tus neeg muab kev pabcuam mus rau tus neeg siv khoom. Lub tsho sab nraud tiv thaiv lub cable los ntawm cov dej noo, UV hluav taws xob thiab lwm yam sab nraud, ua kom ntseeg tau tias kev ntseeg siab thiab kev ua tau zoo mus sij hawm ntev.
Kev teeb tsa ntawm FTTH drop-in optical cable
Kev teeb tsa cov cables FTTH muaj ntau kauj ruam tseem ceeb, suav nrog kev xa cov cable los ntawm qhov chaw faib khoom mus rau cov neeg siv khoom, txiav cov fiber ntawm ob qho kawg, thiab sim qhov kev sib txuas kom ntseeg tau tias ua haujlwm tau zoo. Yuav tsum tau ceev faj tshwj xeeb thaum lub sijhawm teeb tsa kom tsis txhob khoov lossis ua rau cov fiber ntau puas, vim qhov no tuaj yeem ua rau lub cable tsis ua haujlwm zoo thiab ua rau lub teeb liab poob.
Qhov zoo ntawm FTTH poob cables
FTTH poob cables Muaj ntau yam zoo dua li cov xov tooj liab ib txwm muaj, suav nrog lub peev xwm bandwidth siab dua, txo qis lub teeb liab attenuation, thiab tiv thaiv tau ntau dua rau kev cuam tshuam electromagnetic. Qhov no yuav ua rau kev sib txuas hauv internet sai dua, txhim khu kev qha dua, zoo dua lub suab thiab video, thiab kev paub zoo dua rau tus neeg siv. Tsis tas li ntawd, FTTH drop cables ruaj khov dua thiab xav tau kev saib xyuas tsawg dua li cov xov tooj liab, ua rau lawv yog qhov kev daws teeb meem pheej yig thiab yav tom ntej rau kev xa cov kev pabcuam broadband ceev.
Daim ntawv thov ntawm FTTH kev taw qhia optical cable
Cov cables FTTH siv rau ntau yam kev siv xws li thaj chaw nyob, chaw ua lag luam thiab chaw ua haujlwm. Hauv thaj chaw nyob, cov cables FTTH muab kev nkag mus rau hauv Is Taws Nem ceev ceev, IPTV thiab VoIP rau cov tsev neeg, thaum nyob rau hauv chaw ua lag luam thiab chaw ua haujlwm, lawv txhawb nqa cov kev xav tau kev sib txuas lus thiab kev sib txuas lus ntawm cov lag luam thiab cov koom haum.
Hauv kev xaus lus, FTTH drop cables ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev siv dav dav ntawm fiber-to-the-home technology, xa cov internet ceev ceev thiab lwm yam kev pabcuam ncaj qha rau cov neeg siv kawg nrog kev ua tau zoo thiab kev ntseeg siab tsis sib xws. Raws li qhov kev thov rau broadband sai dua, txhim khu kev qha dua txuas ntxiv mus, FTTH drop cables yuav tseem yog ib feem tseem ceeb ntawm cov khoom siv niaj hnub no, tsav tsheb tiam tom ntej ntawm kev sib txuas thiab kev tsim kho tshiab digital.
