Imbaraga hejuru ya Ethernet (PoE) nubuhanga bwogutanga amashanyarazi bushingiye kumurongo waho (LAN), ushobora kohereza ingufu namakuru kubikoresho ukoresheje umugozi wurusobe muri Ethernet. Gukoresha iri koranabuhanga birashobora kugabanya cyane ibiciro byo gukora no kubika igihe cyo gukora. Kugeza ubu, hari uburyo butandukanye bushingiye ku ikoranabuhanga rya PoE ku isoko, cyane cyane PoE ihindura, PoE +, na PoE ++ ihinduka.

PoE ni iki? Guhindura PoE ni iki?

PoE (nanone yitwa IEEE 802.3af isanzwe) ni igipimo gishya gishingiye kuri Power over Ethernet sisitemu yatangajwe nitsinda ryakazi rya IEEE 802.3 mumwaka wa 2003. Igipimo giteganya ko igikoresho cyakira amashanyarazi (PD), nka terefone VoIP , gusa ikeneye gukoresha ibice bibiri byahinduwe byumugozi umwe kugirango bikoreshwe mugihe cyo kwakira amashanyarazi, kandi ingufu za PoE zishobora kugera kuri 12.95W.

PoE ihindura, nanone yitwa PoE itanga amashanyarazi, ni porogaramu ishingiye ku buhanga bwa PoE. Nibihinduka bishobora gutanga ingufu nogukwirakwiza amakuru kuri terefone yakira icyarimwe binyuze mumurongo wumuyoboro, kandi ni mubikoresho bitanga amashanyarazi (PSE). Muri rusange, icyuma cya PoE gihuye na 802.3af gishobora gushyigikira amashanyarazi ntarengwa ya 15.4W kuri buri cyambu, naho ingufu z'amashanyarazi ni 44V-57V. Umuvuduko winjiza wigikoresho cya PoE uhujwe niyi PoE ni 37V-57V.

PoE + ni iki? Niki PoE + ihinduka?

PoE + (nanone yitwa IEEE 802.3af isanzwe), nko kuzamura ikoranabuhanga rya PoE, ni igipimo cya tekiniki cya PoE cyasohotse mu 2009. Hamwe nogukoresha henshi ikoranabuhanga rya PoE, ibikoresho bimwe na bimwe byakira amashanyarazi nka APs idafite ingufu bisaba imbaraga nyinshi cyane kurenza 12.95W. Mu rwego rwo gukemura iki kibazo, itsinda ryakazi rya IEEE 802.3 ryasohoye ikoranabuhanga rya PoE + ryagenewe gutanga ingufu zisumbuye kubikoresho.

Guhindura PoE + bisa na PoE switch twavuze haruguru, kandi itanga imbaraga kubikoresho bya PoE terminal binyuze mumurongo wumuyoboro. Itandukaniro nuko amashanyarazi ntarengwa kuri buri cyambu cya PoE + ni 30W, naho amashanyarazi ni 50V-57V. Amashanyarazi ntarengwa yakiriwe nigikoresho cyakira amashanyarazi arashobora kwiyongera kuri 25.5W, na voltage irashobora kwiyongera kuri 42.5V-57V.

PoE ++ ni iki? Niki PoE ++ ihinduka?

Hamwe niterambere rihoraho ryisoko rya porogaramu ya PoE, IEEE 802.3 isanzwe yongeyeho IEEE 802.3bt. Kuri ubu, tekinoroji ya PoE ++ nayo yagaragaye. Munsi ya IEEE 802.3bt, tekinoroji ya PoE ++ ifite ubwoko bubiri bwamashami. Ikoranabuhanga rimwe rya PoE ++ ryitwa Type3 rishobora gukoreshwa na bibiri cyangwa bine bigoretse byumuyoboro umwe, kandi birashobora gutanga amashanyarazi agera kuri 51W yo kwinjiza ibikoresho byakira amashanyarazi. Ubundi ni tekinoroji ya Type4PoE ++, ikeneye gutanga ingufu kuri PoE igikoresho cya terefone binyuze mubice byose byumuyoboro, kandi imbaraga zinjiza zishobora kugera kuri 71W. Mubyongeyeho, hari tekinoroji ya PoE ishingiye kuri IEEE 802.3bt isanzwe yitwa UPOE (imbaraga rusange kuri Ethernet). Iri koranabuhanga rifite umutungo wa Cisco, kandi uburyo bwo gukora busa na tekinoroji ya Type3PoE (PoE ++), kandi imbaraga zo kwinjiza zishobora gutangwa kubikoresho byakira ni 51W. Kubwibyo, abantu bamwe muruganda nabo bazafata UPOE nka PoE ++.

Nukuzamura kuri PoE yahinduwe na PoE +, PoE ++ irashobora gutanga amashanyarazi agera kuri 60W kuri buri cyambu kuri Type3PoE ++, na 100W kuri Type4. Reba ku mbonerahamwe ikurikira kugirango urebe ibipimo byihariye bya PoE ++ hamwe nubundi bwoko bubiri bwo guhinduranya.
