Kugirango tumenye intera ntarengwa ya PoE, tugomba mbere na mbere kumenya ibintu byingenzi byerekana intera ntarengwa.Mubyukuri, ukoresheje insinga zisanzwe za Ethernet (zigoretse) kugirango wohereze ingufu za DC zirashobora gutwarwa intera ndende, iruta kure cyane ihererekanyabubasha ryibimenyetso.Kubwibyo, intera ntarengwa yo kohereza amakuru nurufunguzo.

1. Intera ntarengwa yohereza imiyoboro ya kabili

Twese tuzi byinshi kuri neti tuzi ko impinduramatwara igoretse ifite intera "itavogerwa" yohereza "metero 100".Yaba Icyiciro cya 3 cyahinduwe hamwe nigipimo cya 10M cyohereza, Icyiciro cya 5 cyahinduwe hamwe na 100M yohereza, cyangwa se Icyiciro cya 6 cyahinduwe hamwe na 1000M yohereza, intera ndende yohereza ni metero 100.

Mubisobanuro byoguhuza insinga, birasabwa kandi neza ko insinga itambitse itagomba kurenga metero 90, kandi uburebure bwurwo rugendo ntibugomba kurenga metero 100.Ibyo byavuzwe, metero 100 ni imipaka kuri Ethernet watsindiye, nuburebure bwumuhuza uva mukarita y'urusobekerane rwibikoresho bya hub.

2. Nigute wabonye intera ntarengwa ya metero 100?

Niki cyateye imipaka yo hejuru ya metero 100 yohereza intera ihindagurika?Ibi bisaba kwibira byimbitse mumahame yimbitse yumubiri yibintu byombi.Ihererekanyabubasha mubyukuri ni ihererekanyabubasha ryibimenyetso kumurongo ugoretse.Nka kimenyetso cya elegitoronike, iyo cyoherejwe mumurongo ugoretse, kigomba guterwa no guhangana nubushobozi, biganisha ku kwangirika no kugoreka ibimenyetso byurusobe.Iyo kwiyegereza cyangwa kugoreka ibimenyetso bigeze kurwego runaka, ihererekanyabubasha ryiza kandi rihamye ryerekana ibimenyetso.Kubwibyo, impinduramatwara ihindagurika ifite aho igarukira.

3. Intera ntarengwa mugihe cyubwubatsi nyabwo

Birashobora kugaragara uhereye hejuru kuki uburebure ntarengwa bwumugozi wurusobe butagomba kurenga metero 100 mugihe ukoresheje amashanyarazi ya PoE.Nyamara, mubwubatsi nyirizina, kugirango tumenye neza umushinga, muri rusange ufata metero 80-90.

Nyamuneka menya ko intera yoherejwe hano yerekeza ku gipimo ntarengwa, nka 100M.Niba igipimo cyaragabanutse kugera kuri 10M, intera yoherejwe irashobora kwagurwa kugera kuri metero 150-200 (bitewe nubwiza bwumugozi wurusobe).Kubwibyo, intera yohereza amashanyarazi ya PoE ntabwo igenwa nubuhanga bwa PoE, ahubwo nubwoko nubwiza bwumugozi.
