Yav tas los, peb tsom mus rau kev nce zog fais fab hla Ethernet hauv peb cov keyboards tsuas yog los ntawm kev nce lub zog xa mus. Txawm li cas los xij, thaum peb siv PoE thiab PoE + cov kev daws teeb meem, nws tau pom tseeb tias qhov no tsis txaus. Peb cov neeg siv khoom tsis yog tsuas yog ntsib nrog cov peev nyiaj fais fab tsawg xwb tab sis kuj nrog cov kev txwv tus qauv ntawm Ethernet networks - qhov ntau ntawm kev xa mus ntawm 100 meters. Hauv tsab xov xwm no, peb yuav piav qhia txog peb kov yeej qhov kev txwv no thiab muab PoE ntev rau qhov kev sim.
Vim li cas thiaj xav tau thev naus laus zis PoE ntev?
Qhov deb ntawm ib puas meters yog ib qho ntev heev. Qhov tseeb, cov xov hlau yeej tsis tau muab tso ua kab ncaj nraim: lawv yuav tsum taug kev txhua qhov nkhaus ntawm lub tsev, nce lossis nqis los ntawm ib txoj kab cable mus rau lwm txoj, thiab lwm yam. Txawm tias nyob rau hauv cov tsev nruab nrab, qhov kev txwv ntawm Ethernet ntu ntev tuaj yeem ua rau tus thawj coj mob taub hau.
Peb tau txiav txim siab siv lub tsev kawm ntawv ua piv txwv los qhia meej tias cov khoom siv twg tuaj yeem tau txais hluav taws xob los ntawm PoE thiab txuas rau lub network (cov hnub qub ntsuab), thiab cov twg tsis tuaj yeem (cov hnub qub liab). Yog tias cov khoom siv network tsis tuaj yeem ntsia tau ntawm cov tsev, ces cov khoom siv ntawm qhov kawg yuav tsis tuaj yeem txuas tau:
Txhawm rau kov yeej qhov kev txwv ntawm ntau yam, Long Range PoE thev naus laus zis siv: nws nthuav dav thaj chaw ntawm lub network wired thiab txuas cov neeg rau npe nyob deb li 250 meters. Nrog Long Range PoE, cov ntaub ntawv thiab lub zog raug xa mus rau ob txoj hauv kev:
- Yog tias qhov ceev ntawm lub interface yog 10 Mbps (Ethernet ib txwm muaj), ces ntawm cov ntu ntev txog 250 meters, nws muaj peev xwm xa ob qho tib si lub zog thiab cov ntaub ntawv.
- Yog tias qhov ceev ntawm lub interface raug teeb tsa rau 100 Mbps (rau cov qauv TL-SL1218MP thiab TL-SG1218MPE) lossis 1 Gbps (rau cov qauv TL-SG1218MPE), yuav tsis muaj cov ntaub ntawv xa mus - tsuas yog fais fab xwb. Hauv qhov no, yuav xav tau lwm txoj kev xa cov ntaub ntawv, xws li txoj kab fiber optic sib luag. Hauv qhov no, Long Range PoE tsuas yog siv rau kev muab hluav taws xob nyob deb xwb.
Yog li, thaum siv Long Range PoE ntawm tib lub tsev kawm ntawv, cov khoom siv network uas txhawb nqa 10 Mbps ceev tuaj yeem nyob txhua qhov chaw.
Cov switches uas muaj kev txhawb nqa Long Range PoE ua tau dab tsi?
