Usibye insinga y'urusobe, ni iki kindi kigira ingaruka ku ntera yohereza amashanyarazi ya PoE?

PoE irashobora kohereza amakuru binyuze mumurongo wurusobe mugihe itanga ingufu kubikoresho bya terefone ya PoE nka simsiz AP, kamera y'urusobe, terefone ya IP, PAD, nibindi, hamwe nintera yohereza metero 100. Kubera ko amashanyarazi ya PoE yoroshye kuyashyiramo no gucomeka no gukina, birakwiriye cyane gukoreshwa mu nganda nkimijyi yubwenge no gukurikirana umutekano.

1. Impamvu nyamukuru zigira ingaruka zo kohereza PoE

1-1. Umuyoboro mwiza

Intera yerekana ibimenyetso byurugero rwicyiciro cya 5 gisanzwe ni metero 100. Urebye ibintu nko guhuza imiyoboro mu buhanga, metero 80-90 muri rusange zifatwa kugirango ubwubatsi bube bwiza. Intera yoherejwe hano yerekeza ku gipimo ntarengwa, nka 100M. Ariko, niba igipimo cyaragabanutse kugera kuri 10M, intera yoherejwe irashobora kwagurwa kugera kuri metero 150-250, bitewe nubwiza bwumugozi.

Intera yo gutanga amashanyarazi ya PoE ifitanye isano rya bugufi nibikoresho bya kabili. Hasi impedance ya kabili y'urusobe, intera ndende.

1-2. Gushyira insinga no gukwirakwiza ubushyuhe

Ubwiyongere bwubushyuhe bwa kabili buzatuma igabanuka ryumuyoboro wa enterineti no gukora igihombo. Mugihe ushyira insinga za PoE, hagomba gusuzumwa ingaruka zo gushyira insinga kumashanyarazi.

Kubwibyo, mugihe ushyira insinga, witondere gukoresha uburyo bufasha gukwirakwiza ubushyuhe.

1-3. Imikorere ya PoE

Umuyoboro ukomeye ntabwo ushingiye gusa ku ntera yo gutanga amashanyarazi ya PoE, ariko kandi ubwiza bwogukwirakwiza imiyoboro bugomba kuba bwizewe. Ukurikije amabwiriza ya IEEE, niba imiyoboro ya kabili irenze metero 100, ubwiza bwikwirakwizwa ntibushobora kwizerwa.

Ariko, mubihe bimwe na bimwe (munsi yigitutu cyibiciro), nkigihe ushyira kamera, intera irashobora kurenga metero 100. Niba intera itari kure cyane, gushiraho igipimo cya kamera kuri 10M birashobora kwagura intera yoherejwe na metero 150-250.

Kugirango ugere ku ntera ndende yoherejwe, PoE switch ifite ibisabwa bikomeye kumurongo wurusobe kandi imikorere yayo nayo irakomeye. Niba chip yo guhinduranya imbere ya PoE ihindura ifite ubushobozi buke bwo kwimenyekanisha kandi ubushobozi bwo gucunga amashanyarazi ntibukomeye, nubwo igipimo cyo kohereza cyaba ari 10M, ntigishobora kwemeza kohereza metero 250, ndetse na metero 150 ntibishobora kugerwaho.

Kugira ngo isoko ryiyongere, JHA Tech yatangije urukurikirane rwohereza intera ndende PoE Switch.

2. 2. Ingingo z'ingenzi

Amashanyarazi ya PoE asabwa cyane insinga. Ubwiza bwinsinga zumuyoboro bujyanye nintera yo kohereza no guhererekanya umutekano wa PoE. Nubuswa kuvuga intera yoherejwe utabanje kureba insinga zurusobe. Mugukurikirana imishinga, ntuzigame ikiguzi cyinsinga, kugirango udahomba ibirenze ibyo wungutse.

Niba ushishikajwe no guhindura tekinoroji ya JHA hamwe nibisubizo, nyamuneka usige imeri yawe hanyuma tuzagire impuguke iguhamagara kubisubizo byumuntu umwe. Bika igihe cyawe cyo kugura nigiciro kandi utezimbere uburyo bwo kugura. Cyangwa utugereho kuriamakuru@jha-ikoranabuhanga.comkuganira kubisanzwe Ethernet ibisubizo bihuye nibyo ukeneye.
