Kupatula chingwe cha netiweki, ndi chiyani chinanso chomwe chimakhudza mtunda wotumizira mphamvu ya PoE?
PoE imatha kutumiza zidziwitso kudzera pa chingwe cha netiweki pomwe ikupereka mphamvu ku zida za PoE terminal monga opanda zingwe AP, network camera, IP phone, PAD, etc., yokhala ndi mtunda wofikira mpaka 100 metres. Popeza makina opangira magetsi a PoE ndi osavuta kuyiyika ndikuyika-ndi-kusewera, ndiyoyenera kugwiritsidwa ntchito m'mafakitale monga mizinda yanzeru komanso kuyang'anira chitetezo.
- Zinthu zazikulu zomwe zimakhudza mtunda wotumizira wa PoE
1-1. Ubwino wa chingwe cha netiweki
Mtunda wotumiza chizindikiro cha data wa zingwe wamba Gulu 5 ndi pafupifupi 100 metres. Poganizira zinthu monga kutsika kwa njira mu engineering, 80-90 metres nthawi zambiri amatengedwa kuti atsimikizire mtundu wa zomangamanga. Mtunda wotumizira pano umatanthawuza kuchuluka kwakukulu, monga 100M. Komabe, ngati mlingowo wachepetsedwa kufika 10M, mtunda wotumizira ukhoza kupitilira mpaka mamita 150-250, malingana ndi khalidwe la chingwe cha intaneti.
Mtunda wamagetsi wa PoE umagwirizana kwambiri ndi zinthu za chingwe cha netiweki. M'munsi mwa impedance ya chingwe cha netiweki, nditalikirapo mtunda wotumizira.
1-2. Kuyika kwa chingwe ndi kutaya kutentha
Kuwonjezeka kwa kutentha kwa chingwe kudzapangitsa kuchepa kwa njira yochepetsera ndikuyika kutayika. Mukayika zingwe za PoE, kukhudzidwa kwa chingwe choyakira pakutaya kutentha kuyenera kuganiziridwa.
Choncho, poika zingwe, tcherani khutu kutengera njira yomwe imapangitsa kuti kutentha kuwonongeke.
1-3. Kusintha kwa PoE
Maukonde olimba samatengera mtunda wamagetsi a PoE, komanso mawonekedwe otumizira ma netiweki ayenera kutsimikiziridwa. Malinga ndi malamulo a IEEE, ngati kutumizira kwa chingwe cha netiweki kupitilira mamita 100, kufalikira kwamtundu sikungatsimikizidwe.
Komabe, nthawi zina (pansi pa kukakamizidwa kwa mtengo), monga kuyika kamera, mtunda ukhoza kupitirira mamita 100. Ngati mtunda suli patali kwambiri, kukhazikitsa kuchuluka kwa kulumikizana kwa kamera ku 10M kumatha kukulitsa mtunda wotumizira wa PoE mpaka 150-250 metres.
Kuti mukwaniritse mtunda wautali wotumizira, chosinthira cha PoE chimakhala ndi zofunikira kwambiri pa chingwe cha netiweki ndipo magwiridwe ake nawonso ndiwofunikira. Ngati chipangizo chosinthira chamkati cha switch ya PoE chili ndi luso lodzisintha komanso luso loyang'anira chip champhamvu silili lolimba, ngakhale kuchuluka kwa kufalikira kumakakamizika kukhala 10M, sikungatsimikizire kufalikira kokhazikika kwa 250 metres, ndipo ngakhale ma 150 metres sangathe. kukwaniritsidwa.
Kuti akwaniritse zosowa zamsika, JHA Tech yakhazikitsa njira zingapo zotumizira anthu mtunda wautali PoE Switch.
- 2. Mfundo zazikuluzikulu
Magetsi a PoE ali ndi zofunika kwambiri pamawaya. Ubwino wa zingwe zama netiweki umagwirizana ndi mtunda wotumizira komanso kukhazikika kwaposachedwa kwa PoE. Ndi zopusa kunena za mtunda wotumizira popanda kuganizira zingwe za netiweki. Poyang'anira ntchito, musasunge ndalama pa mawaya, kuti musataye zambiri kuposa zomwe mumapeza.
Kodi zomwe zili pamwambazi zikuyankha mafunso anu? Ingodinani ulalo kuti muwone zitsanzo zambiri, https://www.jha-tech.com/101001000m-poe-switch/
Ngati muli ndi chidwi ndi Kusintha kwa JHA Technology ndi mayankho, chonde siyani imelo yanu ndipo tidzakhala ndi katswiri wolumikizana nanu kuti mupeze mayankho amodzi ndi amodzi. Sungani nthawi yanu yogula ndi mtengo ndikuwongolera bwino pakugula kwanu. Kapena fikani kwa ife painfo@jha-tech.comkuti mukambirane mayankho amtundu wa Efaneti ogwirizana ndi zosowa zanu.
