Fiber-to-the-home (FTTH) thev naus laus zis tau hloov pauv txoj hauv kev uas peb nkag mus rau hauv is taws nem, muab kev sib txuas ceev thiab txhim khu kev qha ntau dua li yav dhau los. Lub hauv paus ntawm cov thev naus laus zis no yog FTTH nco cable, lub ntsiab lus tseem ceeb hauv kev xa cov internet ceev ceev mus rau tsev thiab kev lag luam. Hauv phau ntawv qhia no, peb yuav tshawb xyuas txhua yam koj xav paub txog FTTH nco cables, los ntawm lawv cov kev tsim kho thiab kev teeb tsa rau lawv cov txiaj ntsig thiab kev siv.
FTTH drop cable yog dab tsi?
FTTH poob cable, tseem hu ua fiber ntau optic nco cable, yog fiber ntau optic cable tshwj xeeb tsim los txuas kho qhov muag network terminals (ONTs) rau cov neeg siv khoom hauv tsev hauv fiber ntau hauv tsev. Nws yog qhov kawg txuas hauv FTTH network, xa high-speed Internet, TV thiab xov tooj kev pabcuam ncaj qha rau cov neeg siv kawg.
Kev tsim kho ntawm FTTH kev taw qhia kho qhov muag cable
FTTH nco cables feem ntau muaj lub hauv paus muaj zog cov tswv cuab nyob ib puag ncig ntawm fiber ntau optics thiab tiv thaiv sab nrauv. Cov tswv cuab lub zog hauv nruab nrab muab qhov tsim nyog tensile lub zog rau cable los tiv thaiv kev teeb tsa thiab ib puag ncig kev ntxhov siab, thaum lub fiber ntau optical nqa cov ntaub ntawv teeb liab los ntawm cov chaw muab kev pabcuam rau cov neeg siv khoom. Lub tsho sab nrauv tiv thaiv cov kab hluav taws xob los ntawm kev ya raws, UV hluav taws xob thiab lwm yam khoom siv sab nraud, ua kom muaj kev ntseeg tau ntev thiab kev ua haujlwm.
Kev teeb tsa ntawm FTTH nco-hauv optical cable
Kev teeb tsa ntawm FTTH nco cables suav nrog ntau cov kauj ruam tseem ceeb, suav nrog kev xa cov kab hluav taws xob los ntawm qhov chaw xa mus rau cov neeg siv khoom, txiav cov fiber ntau ntawm ob qho kawg, thiab ntsuas qhov kev sib txuas kom ua haujlwm tau zoo. Kev saib xyuas tshwj xeeb yuav tsum tau ua thaum lub sijhawm teeb tsa kom tsis txhob khoov lossis ua kom puas lub fiber ntau optical, vim qhov no tuaj yeem ua rau kev ua haujlwm ntawm lub cable thiab ua rau lub teeb liab poob.
Qhov zoo ntawm FTTH poob cables
FTTH poob cables muab ntau qhov zoo dua li cov xov tooj tooj liab, nrog rau kev muaj peev xwm bandwidth ntau dua, txo cov teeb liab attenuation, thiab kev tiv thaiv ntau dua rau electromagnetic cuam tshuam. Qhov no yuav ua rau muaj kev sib txuas hauv internet sai dua, txhim khu kev qha, txhim kho lub suab thiab video zoo, thiab txhim kho tag nrho cov neeg siv kev paub. Tsis tas li ntawd, FTTH nco cables yog qhov ruaj khov dua thiab yuav tsum muaj kev saib xyuas tsawg dua li tooj liab cables, ua rau lawv muaj txiaj ntsig zoo thiab muaj txiaj ntsig yav tom ntej rau kev xa cov kev pabcuam siab ceev.
Daim ntawv thov ntawm FTTH taw qhia kho qhov muag cable
FTTH nco cables yog siv nyob rau hauv ib tug ntau yam ntawm daim ntaub ntawv, nrog rau cov chaw nyob, coj mus muag thiab kev lag luam ib puag ncig. Hauv thaj chaw nyob ib puag ncig, FTTH poob cables muab kev siv Internet ceev ceev, IPTV thiab VoIP cov kev pabcuam rau ib tus neeg lub tsev, thaum nyob rau hauv kev lag luam thiab kev lag luam ib puag ncig, lawv txhawb kev sib txuas lus thiab kev sib txuas lus ntawm cov lag luam thiab cov koom haum.
Hauv cov ntsiab lus, FTTH nco cables ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev siv ntau ntawm fiber ntau rau hauv tsev, xa cov Internet ceev thiab lwm yam kev pabcuam ncaj qha rau cov neeg siv kawg uas tsis muaj kev sib piv thiab kev ntseeg tau. Raws li kev thov kom sai dua, txhim khu kev qha broadband txuas ntxiv mus, FTTH poob cables yuav tseem yog ib feem tseem ceeb ntawm kev lag luam niaj hnub no, tsav cov tiam tom ntej ntawm kev sib txuas thiab kev tsim kho digital.
