Cov lus teb tseem ceeb: Yog, tab sis nws tsis yog "kev hloov pauv ncaj qha." Hloov chaw, cov thev naus laus zis tshwj xeeb yog siv los txhawb koj cov kab coaxial cable uas twb muaj lawm rau kev xa cov ntaub ntawv Ethernet. Qhov no yog ib txoj hauv kev zoo thiab paub tab rau kev txhim kho thiab hloov koj lub network hauv tsev.
Hauv qab no, kuv yuav muab ib qho kev ntsuam xyuas dav dav los ntawm qhov kev xav ntawm cov qauv kev siv tshuab, cov phiaj xwm kev siv, kev sib piv zoo, thiab cov kev xav tseem ceeb.
I. Technical Principple: Nws tsis yog "Conversion," tab sis "Multiplexing"
Koj tsis tuaj yeem hloov pauv lub coaxial cable txuas rau RJ45 ntsaws zoo li hloov lub ntsaws. Lawv cov qauv teeb liab hluav taws xob thiab cov txheej txheem sib txawv kiag li.
Coaxial Cable:Kev lig kev cai tsim los xa xov tooj cua zaus (RF) cov cim, xws li TV teeb liab, ua haujlwm hauv ntau zaus.
Ethernet (Twisted Pair):Tsim los xa cov teeb liab baseband digital (0s thiab 1s).
Yog li ntawd, tus yuam sij rau kev ua tiav "kev hloov pauv" yog ntxiv cov khoom siv tshwj xeeb (modems) ntawm ob qho kawg ntawm cov kab hluav taws xob los ua cov teeb liab modulation thiab demodulation.
Cov txheej txheem no tuaj yeem ua tau raws li hauv qab no:
Koj lub tsev lub coaxial cable zoo li "txoj kev loj" uas yav tas los tsuas tso cai rau "TV teeb liab" tsheb. Tam sim no, peb tsim "logistics hub" (adapter) ntawm txhua qhov kawg ntawm txoj kev loj (xws li kev kawm thiab chav nyob). Koj "Ethernet data packets" yog disassembled thiab ntim rau hauv "RF teeb liab tsheb" muaj peev xwm taug kev ntawm txoj kev loj ntawm qhov kawg xa. Lawv raug thauj los ntawm coaxial cable mus rau lwm qhov kawg, qhov twg lwm qhov chaw logistics reassembles lawv rov qab rau hauv "Ethernet data packets." Txoj kab ntawm lub cev tseem tsis hloov pauv, tab sis cov ntsiab lus thiab txoj kev thauj mus los hloov pauv.
II. Cov ncauj lus kom ntxaws txog Mainstream Technical Solutions
Tam sim no, qhov tseem ceeb tshaj plaws thiab pom zoo siv tshuab rau cov neeg siv hauv tsev yogMoCA (Multimedia tshaj Coax Alliance).
1. MoCA Technology
Nws ua haujlwm li cas:Siv lub siab -ntau zaus bands nyob rau hauv coaxial cable uas tsis nyob los ntawm TV teeb liab (feem ntau ntawm 1000-2500 MHz) xa cov teeb liab network. Nws tuaj yeem koom nrog cable TV lossis satellite teeb liab uas twb muaj lawm yam tsis muaj kev cuam tshuam.
Kev ua tau zoo:
Ceev:Lub ntsiabMOCA 2.5tus qauv tuaj yeem muab txog li 2.5 Gbps raw lub cev txheej txheej. Qhov tseeb usable Ethernet ports feem ntau yog 1 Gbps lossis 2.5 Gbps. Qhov no txaus los txhawb txhua qhov siab -cov ntawv thov hauv tsev ceev xws li 4K/8K streaming, online gaming, thiab cov ntaub ntawv loj.
Latency:Tsawg heev, piv rau wired Ethernet thiab deb tshaj Wi-Fi.
Kev ruaj ntseg:Tsis muaj kev cuam tshuam los ntawm kev cuam tshuam wireless lossis phab ntsa attenuation, muab kev sib txuas ruaj khov nyob ze ntawm lub cev network cable.
Topology yuav tsum tau:Lub coaxial cable outlets nyob rau hauv koj lub tsev yuav tsum tsim ib tug " siv tau network." Feem ntau, coaxial cables los ntawm tag nrho cov chav converge ntawm ib tug splitter nyob rau hauv ib tug central low -voltage enclosure (structured wiring panel). Txhawm rau siv MoCA, koj yuav tsum xyuas kom meej tias lub splitter txhawb MoCA zaus ntau yam (feem ntau yog 5-2500 MHz). Tej zaum koj kuj yuav tau ntxiv ibMoCA lim (PoE lim)sab hauv vaj huam sib luag los tiv thaiv cov teeb liab tawm sab nraum zoov thiab txhim khu kev ruaj ntseg.
2. Lwm yam kev daws teeb meem (Rau kev paub tsuas yog, tsis pom zoo ua thawj zaug)
DECA (DirecTV Ethernet dhau Coax Adapter):Tsuas yog tsim nyog rau DirecTV satellite TV cov neeg siv. Tsawg bandwidth (~ 100 Mbps) thiab tej zaum yuav tsis sib haum nrog lwm lub tshuab.
HPNA over Coax:Cov thev naus laus zis qub, feem ntau hloov los ntawm MoCA.
EoC (Ethernet dhau Coax):Qhov no yog ib lub ntsiab lus dav dav uas suav nrog ntau yam coaxial Ethernet thev naus laus zis, ntau dua hauv cov neeg siv xov tooj thiab cov kab ke kev nyab xeeb. Cov khoom siv qib- feem ntau xa mus rau MoCA adapters.
III. Vim li cas qhov no yog ib qho kev daws teeb meem zoo? (Qhov zoo)
Siv Infrastructure uas twb muaj lawm:Tsis tas yuav khiav cov kab txuas tshiab hauv cov phab ntsa, zam kev puas tsuaj rau décor. Nws yog qhov kev daws teeb meem zoo tshaj plaws rau "cov teeb meem zais zais."
Kev ua tau zoo tshaj:Muab qhov ruaj khov, siab -bandwidth ceev piv rau lossis tseem tshaj Cat 5e/6 cables. Nws yog qhov zoo tagnrho rau kev sib txuas rov qab (Mesh networking), game consoles, NAS li, thiab lwm yam khoom siv uas xav tau kev ua haujlwm siab hauv network.
Synergy nrog WiFi:Ua haujlwm zoo tshaj plaws backhaul rau tag nrho -tsev Mesh WiFi system. Txuas lub ntsiab Mesh node rau MoCA adapter, thiab sub-nodes hauv lwm chav ntawm lawv tus kheej MoCA adapters, ua tiav qhov tsis muaj gigabit / ntau ntau-gigabit wireless kev pab cuam thoob plaws hauv tsev.
Relatively Simple Deployment:Feem ntau ntsaws-thiab- ua si nrog kev teeb tsa yooj yim.
IV. Cov kauj ruam ntawm kev ua thiab kev yuav khoom tawm tswv yim
Standard Implementation Cov kauj ruam:
Paub meej Coaxial Kab:Nrhiav cov kab hluav taws xob coaxial hauv cov chav koj xav tau txuas thiab nrhiav qhov nruab nrab qis -voltage enclosure.
Tshawb xyuas qhov Enclosure:Qhib nws thiab paub meej tias muaj cov coaxial splitter. Hloov nws nrog aMoCA 2.x raws li dav dav splitter (5-2500 MHz).
Nruab MoCA Lim:Nyob rau hauv lub enclosure, nruab lub lim ntawm qhov chaw uas lub ntsiab nkag mus rau lub splitter lub input chaw nres nkoj.
Yuav MoCA Adapters:Koj xav tau ib qho rau txhua chav xav tau kev sib txuas. Yam tsawg kawg yog ob qho yuav tsum tau ua ib khub ua haujlwm.
Txuas Devices:
Txuas lub LAN chaw nres nkoj ntawm koj lub router mus rau Ethernet chaw nres nkoj ntawm Adapter A siv lub network cable.
Txuas Adapter A rau phab ntsa coaxial qhov hluav taws xob siv lub coaxial cable.
Hauv lwm chav, txuas Adapter B rau phab ntsa coaxial qhov hluav taws xob.
Thaum kawg, txuas Ethernet chaw nres nkoj ntawm Adapter B rau koj lub computer, game console, TV, lossis Mesh satellite node siv lub network cable.
Power On thiab Pair:Feem ntau, adapters cia li pom ib leeg thiab tsim kev sib txuas. Qhov taw qhia teeb pom kev sib txuas.
Cov lus qhia txog kev yuav khoom:
Nrhiav tus Standard:Yuav cov adapters txhawb nqaMOCA 2.5rau kev ua tau zoo. Cov hom muaj xws li Actiontec (tam sim no ScreenBeam), Motorola, Hitron, gocoax, thiab lwm yam.
Nco tseg Port Ceev:Adapters muaj Ethernet chaw nres nkoj ntawm 1 Gbps lossis 2.5 Gbps. Xaiv raws li koj lub router thiab cov khoom xav tau.
Yuav hauv Cov Khoom Siv:Rau thawj zaug - siv sijhawm, nws raug nquahu kom yuav ob - pob (ib khub) cov khoom siv kom ntseeg tau tias muaj kev sib raug zoo.
V. Kev txiav txim siab tseem ceeb (Kev txwv)
Kab yuav tsum tau txuas:Lub qhov hluav taws xob coaxial nyob rau hauv ob chav koj xav siv yuav tsum tau txuas nrog lub cev ntawm lub splitter hauv lub qhov rooj. Yog tias txoj kab raug txiav tawm, nws yuav tsum tau rov txuas dua ua ntej.
Splitter thiab Filter yog qhov tseem ceeb:Tsawg-zoo lossis tsis sib xws tuaj yeem ua rau muaj teeb meem loj heev lossis ua tsis tiav. MoCA lim yog qhov tseem ceeb.
Tus nqi:Ib khub ntawmMoCA 2.5 adapterstus nqi ib ncig $100-150, uas yog thawj zaug peev. Txawm li cas los xij, xav txog kev txhim kho kev ua haujlwm thiab kev yooj yim, nws muab cov nqi-zoo.
Tsis yog "Infinitely Scalable":Thaum MoCA network tuaj yeem txhawb nqa txog li 16 ntawm, txhua qhov sib faib tag nrho cov bandwidth. Rau feem coob ntawm cov tsev (3-5 nodes), bandwidth ntau tshaj qhov txaus.
Xaus
Yog tias koj lub tsev tau ua ntej- teeb tsa coaxial cables thiab koj yuav tsum tsim kom muaj siab- nrawm, ruaj khov, qis-latency wired network kev sib txuas ntawm chav tsis muaj rewiring, tom qab ntawd sivMoCA 2.5 technologyyog koj txoj kev xaiv tshaj plaws thiab txhim khu kev qha. Nws ua tiav kev hloov pauv sai sai no - mus rau - yuav - TV cable tsis tau siv rau hauv lub siab - kev ua tau zoo hauv tsev Ethernet qaum, zoo kawg nkaus daws cov teeb meem ntawm kev sib tw ntawm cov tsev ntse niaj hnub.
Tso tseg lub tswv yim ntawm "txoj kev hloov pauv ncaj qha" lossis siv cov khoom siv hluav taws xob qis -kev ua tau zoo. Ua lag luam nyob rau hauv ib txheej ntawm MoCA adapters, thiab koj yuav muaj kev vam meej leap hauv koj lub network kev ua tau zoo.
