Dhau li ntawm lub network cable, dab tsi ntxiv cuam tshuam rau PoE fais fab kis nrug deb?
PoE tuaj yeem xa cov ntaub ntawv los ntawm lub network cable thaum muab lub zog rau PoE cov khoom siv davhlau ya nyob twg xws li wireless AP, lub koob yees duab network, IP xov tooj, PAD, thiab lwm yam, nrog rau kev sib kis mus txog 100 meters. Txij li thaum lub tshuab hluav taws xob PoE yooj yim rau nruab thiab ntsaws-thiab-ua si, nws yog qhov tsim nyog rau kev siv hauv kev lag luam xws li cov nroog ntse thiab kev saib xyuas kev ruaj ntseg.
- Cov yam tseem ceeb cuam tshuam rau PoE kis nrug deb
1-1. Network cable zoo
Cov ntaub ntawv teeb liab kis tau tus mob nyob deb ntawm qhov zoo tib yam Qeb 5 cables yog hais txog 100 meters. Xav txog yam xws li channel attenuation hauv engineering, 80-90 meters feem ntau yog coj los xyuas kom meej kev tsim kho zoo. Qhov kev sib kis ntawm no yog hais txog qhov siab tshaj plaws, xws li 100M. Txawm li cas los xij, yog tias tus nqi txo mus rau 10M, qhov kev sib kis tau ntev tuaj yeem txuas ntxiv mus rau 150-250 meters, nyob ntawm qhov zoo ntawm lub network cable.
PoE fais fab mov nrug ze ze rau cov khoom siv ntawm lub network cable. Qhov qis dua qhov impedance ntawm lub network cable, qhov kev sib kis ntev dua.
1-2. Cable tso thiab cua sov dissipation
Qhov kev nce hauv cable kub yuav ua rau txo qis hauv cov channel attenuation thiab kev ua haujlwm tsis zoo. Thaum tso PoE cables, qhov cuam tshuam ntawm cable tso rau ntawm tshav kub dissipation yuav tsum xav txog.
Yog li ntawd, thaum tso cables, xyuam xim rau kev siv ib txoj kev uas yog conducive rau tshav kub dissipation.
1-3. PoE hloov kev ua haujlwm
Lub network muaj zog tsis tsuas yog nyob ntawm PoE fais fab mov nrug, tab sis kuj yuav tsum tau lees tias qhov kev sib kis zoo hauv network. Raws li IEEE cov kev cai, yog tias lub network cable kis tau tus mob siab tshaj 100 meters, qhov kis tau tus mob zoo yuav tsis lav.
Txawm li cas los xij, qee zaum (nyob rau hauv tus nqi siab), xws li thaum txhim kho lub koob yees duab, qhov kev ncua deb yuav tshaj 100 meters. Yog tias qhov kev ncua deb tsis deb dhau, teeb tsa lub koob yees duab txuas mus rau 10M tuaj yeem txuas ntxiv PoE kis mus rau 150-250 meters.
Txhawm rau kom ua tiav qhov kev sib kis ntev dua, qhov hloov pauv PoE muaj cov kev cai nruj ntawm lub network cable thiab nws tus kheej kev ua tau zoo kuj tseem ceeb heev. Yog tias qhov hloov pauv sab hauv ntawm PoE hloov pauv muaj peev xwm hloov kho tus kheej tsis zoo thiab lub zog nti tswj lub peev xwm tsis muaj zog, txawm tias tus nqi sib kis tau raug yuam kom yog 10M, nws tsis tuaj yeem lav qhov kev sib kis ruaj khov ntawm 250 meters, thiab txawm tias 150 meters tsis tuaj yeem. ua tiav.
Txhawm rau ua kom tau raws li kev xav tau ntawm kev lag luam, JHA Tech tau tshaj tawm cov kev sib kis mus ntev PoE Hloov.
- 2. Cov ntsiab lus tseem ceeb
PoE fais fab mov muaj cov kev xav tau siab rau cov xov hlau. Qhov zoo ntawm cov cables network yog cuam tshuam nrog kev sib kis deb thiab kev ruaj ntseg ntawm PoE. Nws yog ruam los tham txog kev sib kis deb yam tsis xav txog cov kab hluav taws xob network. Hauv kev saib xyuas cov haujlwm, tsis txhob txuag cov nqi ntawm cov xov hlau, kom tsis txhob poob ntau tshaj qhov koj tau txais.
