POE Power Over Ethernet yog dab tsi? - Network Technology Guide
Fais fab dhau Ethernet (PoE) yog qhov kev ua si-hloov thev naus laus zis rau niaj hnub network. Nws cia cov ntaub ntawv thiab lub zog ntws los ntawm ib qho Ethernet cable. Qhov no ua rau kev sib txuas thiab siv cov khoom siv hluav taws xob yooj yim dua thiab ua haujlwm tau zoo hauv ntau qhov chaw.
PoE yog qhov tseem ceeb rau kev teeb tsa network, muab txoj hauv kev yooj yim thiab pheej yig rau cov khoom siv hluav taws xob. Qhov no suav nrog IP koob yees duab, cov ntsiab lus nkag wireless, VoIP xov tooj, thiab ntse sensors.
PoE cia Ethernet keyboards lossis lwm yam khoom siv hluav taws xob sib txuas ncaj qha. Qhov no txhais tau tias tsis tas yuav tsum muaj cov khoom siv hluav taws xob ntxiv lossis cov khoom hloov pauv. Nws ua rau kev teeb tsa yooj yim dua, txo qis kev ntxhov siab, thiab txhawb nqa kev ua haujlwm hauv network, tshwj xeeb tshaj yog qhov chaw hluav taws xob nyuaj nrhiav.

PoE ua haujlwm li cas?
| PoE Standard | Kev xa hluav taws xob siab tshaj plaws |
| 802.3af (PoE) | 15,4 w :ua |
| 802.3at (PoE +) | 30 watt |
| 802.3bt (PoE++) | 9 0 watt |
PoE Standards thiab Classifications
IEEE 802.3af (PoE)
Tus qauv IEEE 802.3af, tseem hu ua PoE, yog thawj zaug ntaus. Nws tso cai rau cov khoom siv tau txog li 15.4 watts ntawm lub zog, nrog tsawg kawg 12.95 watts rau lub cuab yeej nws tus kheej.
IEEE 802.3at (PoE +)
Tus qauv IEEE 802.3at, lossis PoE +, nce lub zog rau 30 watts. Qhov no txhais tau tias cov khoom siv xws li PTZ koob yees duab thiab cov ntsiab lus nkag wireless tuaj yeem tau txais lub zog ntau dua.
IEEE 802.3bt (PoE++ lossis 4PPoE)
Tus qauv tshiab, IEEE 802.3bt, lossis PoE ++ lossis 4PPoE, mus ntxiv. Nws tso cai rau txog li 90 watts ntawm lub zog, ua rau nws zoo meej rau cov khoom siv hluav taws xob zoo li LED teeb thiab cov iav muaj zog.
Hwj chim Classes thiab lawv Specifications
PoE cov qauv muaj cov chav kawm fais fab sib txawv. Cov chav kawm no muaj txij li Chav Kawm 0 txog Chav Kawm 8, txhua tus muaj nws tus kheej lub zog. Ntawm no yog ib lub rooj qhia lub zog specs rau txhua chav kawm:
| Hwj chim Class | Lub zog siab tshaj plaws ntawm Lub Hwj Chim Loj | Tsawg zog ntawm Powered Device |
| Chav Kawm 0 | 15.4 wb | 0.44 W - 12.95 W |
| Chav Kawm 1 | 4in ib | 0.44 W - 3.84 W |
| Chav kawm 2 | 7 W | 3.84 W - 6.49 W |
| Chav kawm 3 | 15.4 wb | 6.49 W - 12.95 W |
| Chav Kawm 4 | 30 W | 12.95 W - 25.5 W |
| Chav Kawm 5 | 45 wb | 25.5-40 W |
| Chav Kawm 6 | 60 wb | 40 W - 51 W |
| Chav Kawm 7 | 75 wb | 51 W - 62 W |
| Chav Kawm 8 | 90 wb | 62 W - 71 W |
Kev siv ntawm PoE: PoE Devices
Lub zog dhau Ethernet (PoE) thev naus laus zis tam sim no muaj nyob hauv ntau lub network. Nws yog siv nyob rau hauv ntau yam khoom siv thiab tshuab. Los ntawm poe zog dhau ethernet li mus rau poe fais fab dhau ethernet daim ntawv thov, PoE tau hloov pauv peb lub zog thiab txuas ntau qhov chaw ntawm poe fais fab ntawm ethernet systems.
Ib qho kev siv loj ntawm PoE yog nyob rau hauv IP koob yees duab thiab kev soj ntsuam systems. Cov khoom siv no tau txais lub zog thiab cov ntaub ntawv los ntawm ib qho Ethernet cable. Qhov no ua rau kev teeb tsa yooj yim dua thiab tshem tawm qhov xav tau ntawm cov khoom siv hluav taws xob ntxiv.
PoE tseem yog qhov tseem ceeb hauv Suab tshaj IP (VoIP) xov tooj. Nws pab cov xov tooj no ua haujlwm ua haujlwm zoo hauv chaw ua haujlwm. Qhov no ua rau kev sib txuas lus zoo dua thiab sib koom ua ke.
PoE yog qhov zoo rau wireless access point thiab IoT sensors ib yam nkaus. Cov poe fais fab ntawm cov khoom siv ethernet tuaj yeem teeb tsa txhua qhov chaw yam tsis xav tau cov hluav taws xob hluav taws xob. Qhov no yog vim PoE xa ob qho tib si cov ntaub ntawv thiab lub zog hla ib qho Ethernet cable. Nws zoo meej rau cov tsev ntse, cov chaw ua lag luam, thiab IoT systems.
| PoE-Powered Device | Daim ntawv thov |
| Cov koob yees duab IP | Kev soj ntsuam thiab kev ruaj ntseg systems |
| VoIP Xov tooj | Kev sib koom ua ke sib txuas lus hauv chaw ua haujlwm ib puag ncig |
| Wireless Access Points | Kev sib txuas wireless hauv cov tsev ntse thiab IoT tes hauj lwm |
| IoT Sensors | Saib xyuas thiab automation hauv kev lag luam thiab kev lag luam |
Qhov zoo ntawm Kev Siv PoE
PoE, lossis Lub Hwj Chim dhau Ethernet, yog lub network thev naus laus zis nrog ntau yam txiaj ntsig. Nws yooj yim installation thiab boosts zog efficiency. Qhov no ua rau nws yog qhov zoo tshaj plaws xaiv rau cov khoom siv hluav taws xob hauv tes hauj lwm.
Ib qho loj poe zog tshaj ethernet txiaj ntsig yog xa cov ntaub ntawv thiab lub zog los ntawm ib qho Ethernet cable. Qhov no txo qis ntawm kev sib tsoo thiab ua rau kev teeb tsa yooj yim dua. Ntxiv rau, poe zog efficiency txhais tau tias tsawg zog siv, txuag nyiaj nyob rau hauv lub sij hawm ntev.
Lwm lub zog poe tshaj ethernet kom zoo dua yog nws yooj. Cov khoom siv tuaj yeem mus qhov twg lawv xav tau, yam tsis xav tau cov hluav taws xob hluav taws xob. Qhov kev hloov pauv no yog qhov zoo rau kev teeb tsa cov ntsiab lus nkag wireless, IP koob yees duab, thiab xov tooj VoIP.
Thaum kawg, poe kev ua tau zoo yog ib tug loj ntxiv. Nws txuag ntawm kev teeb tsa thiab kho cov nqi uas tsis xav tau cov tshuab hluav taws xob sib cais. Qhov no ua rau PoE txaus siab rau txhua yam kev lag luam, loj lossis me.
Kev siv PoE tuaj yeem ua rau kev teeb tsa network yooj yim dua, txhim kho kev siv hluav taws xob, thiab txuag nyiaj. Nws yog qhov kev xaiv ntse rau ntau daim ntawv thov.
