Hauv lub ntiaj teb niaj hnub no uas muaj kev sib txuas ceev ceev, qhov twg kev sib txuas ua lub luag haujlwm tseem ceeb hauv txhua yam ntawm peb lub neej, nws yog qhov tseem ceeb heev kom muaj cov kev daws teeb meem network txhim khu kev qha thiab ua tau zoo los ua kom tau raws li ntau yam kev xav tau ntawm tsev neeg. Nrog rau kev tshwm sim ntawm cov thev naus laus zis siab heev xws li CATV ONUs (Optical Network Units), peb tab tom pom kev txhim kho tshiab hauv kev sib txuas hauv tsev. Hauv tsab ntawv blog no, peb yuav nkag mus rau hauv lub ntiaj teb zoo siab ntawm CATV ONU, nws cov peev xwm, thiab nws tuaj yeem hloov pauv kev sib txuas hauv tsev li cas.
Ua ke nrog dual-fiber peb-yoj thev naus laus zis:
CATV ONUyog tsim los ntawm kev siv thev naus laus zis dual-fiber thiab triple-wave los xyuas kom muaj kev sib txuas lus hauv Is Taws Nem ruaj khov thiab ceev ceev. Cov thev naus laus zis tshiab no muab lub zog ntawm fiber optics los xa cov ntaub ntawv, lub suab thiab cov teeb liab video tib lub sijhawm, muab rau cov neeg siv nrog kev paub online zoo thiab tsis muaj kev cuam tshuam.
Pawg Neeg Saib Xyuas Kev Lag Luam Kev Tshaj Tawm thiab Kev Ua Yeeb Yam FTTH:
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm CATV ONU yog nws lub rooj tsavxwm kev pabcuam sib koom ua ke, uas tuaj yeem sib koom ua ke xov tooj cua thiab TV FTTH (fiber rau lub tsev) cov kev pabcuam. Nrog rau kev sib koom ua ke no, cov neeg siv tuaj yeem txaus siab rau ntau yam xov tooj cua thiab TV channel los ntawm kev nplij siab ntawm lawv lub tsev, txhim kho lawv cov kev lom zem. Los ntawm kev siv lub zog ntawm kev txais tos optical, CATV ONU ua kom ntseeg tau tias kev txais tos teeb liab thiab kev xa mus zoo tshaj qhov kev daws teeb meem tooj liab ib txwm muaj.
Wireless WiFi thiab CATV lub teeb txais tos muaj nuj nqi:
CATV ONU muab kev sib txuas wireless WiFi thiab CATV optical reception peev xwm los tshaj qhov kev daws teeb meem kev sib txuas ib txwm muaj. Qhov kev sib koom ua ke no ua rau cov neeg siv tau yooj yim teeb tsa LAN hauv tsev (Local Area Network). CATV ONU muab 4 Ethernet interfaces thiab wireless WiFi kev sib txuas, tso cai rau ntau lub cuab yeej txuas thiab sib koom cov peev txheej tib lub sijhawm. Txawm hais tias streaming movies, online games, lossis ua haujlwm hauv tsev, lub tsev LAN tsim los ntawm CATV ONU pab txhawb kev sib txuas seamless thiab sib koom cov ntaub ntawv hauv tsev.
Txhawb nqa Internet thiab cable TV tshaj tawm thiab kev pabcuam TV:
Los ntawm CATV ONU, cov neeg siv tsis tsuas yog tuaj yeem txaus siab rau cov kev pabcuam hauv Is Taws Nem tsis muaj kev cuam tshuam, tab sis kuj nkag mus rau cov ntaub ntawv tshaj tawm CATV loj thiab cov ntsiab lus hauv TV. Los ntawm kev siv Ethernet interface thiab wireless WiFi, CATV ONU ua rau cov neeg siv tuaj yeem xauj Is Taws Nem ntawm qhov ceev ceev ntawm EPON (Ethernet Passive Optical Network). Tib lub sijhawm, CATV optical receiver tau txais cov teeb liab TV digital kom ntseeg tau tias cov neeg siv tau txais kev paub TV zoo, txhais tau zoo. Kev sib koom ua ke ntawm Is Taws Nem thiab cable TV cov kev pabcuam ua rau pom qhov pom ntawm fiber-rau-lub-tsev (FTTH), muab cov neeg siv nrog kev daws teeb meem kev sib txuas.
Hauv kev xaus lus:
Hauv luv luv,CATV ONUthev naus laus zis tau hloov pauv tag nrho cov kev sib txuas hauv tsev los ntawm kev sib txuas ob lub fiber thiab peb lub nthwv dej thev naus laus zis, kev sib koom ua ke ntawm cov laug cam kev pabcuam, wireless WiFi thiab CATV optical txais tos cov haujlwm. Qhov kev tsim kho tshiab no tau ua rau muaj kev sib txuas thiab sib koom ua ke hauv tsev, muab kev pabcuam hauv Is Taws Nem tsis muaj kev cuam tshuam thiab cov ntsiab lus tshaj tawm cable thiab TV nplua nuj. Nrog CATV ONU, tsev neeg tuaj yeem txais yuav yav tom ntej ntawm kev sib txuas thiab txaus siab rau Is Taws Nem ceev ceev, TV siab txhais thiab kev lom zem tsis muaj qhov kawg.
