Niki Imbaraga kuri Ethernet (POE)

Imbaraga hejuru ya Ethernet (PoE) ni tekinoroji ihindura ituma insinga zumuyoboro wohereza amashanyarazi kumashanyarazi kubikoresho bitandukanye murusobe, bikuraho ibikenerwa byamashanyarazi cyangwa adaptate zitandukanye. Ubu buryo bworoshya kwishyiriraho ibikoresho, kuko bishobora kwakira imbaraga namakuru byombi binyuze mumurongo umwe, byoroha guhinduka no gukora neza mukubaka ibikorwa remezo.

Ese insinga zose za Ethernet zishyigikira PoE?

Ntabwo insinga zose za Ethernet zakozwe zingana mugihe cyo gushyigikira PoE. Mugihe insinga za Cat5e cyangwa zisumba Ethernet zishobora gushyigikira PoE, insinga za Cat5 zishobora gukora gusa voltage yo hasi. Gukoresha insinga za Cat5 kugirango ubone ingufu Icyiciro cya 3 cyangwa Icyiciro cya 4 Ibikoresho bikoresha (PDs) bishobora gutera ibibazo byubushyuhe. Kubwibyo, ni ngombwa guhitamo ubwoko bukwiye bwa kabili kubyo PoE ukeneye.

Porogaramu ya PoE

Ubwinshi bwa PoE bukubiyemo ibintu byinshi bikoreshwa mubice bitandukanye. Bimwe mubikoresho bisanzwe bishobora gukoreshwa hakoreshejwe PoE harimo:

Amatara ya LED, Kiosks, sensor ya Occupancy, Sisitemu yo kumenyesha, Kamera, Monitor, igicucu cya Window, mudasobwa zigendanwa za USB-C, mudasobwa zigendanwa, na firigo.

Iterambere mubipimo bya PoE

Ibipimo bigezweho mu ikoranabuhanga rya PoE bizwi nka Hi PoE (802.3bt Ubwoko bwa 4), bushobora gutanga amashanyarazi agera kuri 100 W binyuze mu nsinga za Cat5e. Iterambere ryemerera gukoresha ingufu nyinshi zikoresha ingufu, guteza imbere udushya no gukora. Nyamara, ni ngombwa kumenya ko kongera amashanyarazi bishobora gutuma habaho ubushyuhe bwinshi no gutakaza ingufu nyinshi muri kabili.

Ibyifuzo byo gukoresha neza PoE

Kugabanya ibibazo bishobora guterwa n'ubushyuhe no gutakaza ingufu, abahanga barasaba gukoresha insinga z'umuringa 100%, zitanga uburyo bwiza bwo kubaho no kuramba. Byongeye kandi, kwirinda gukoresha inshinge za PoE cyangwa guhinduranya bidashobora gushyigikira gutanga amashanyarazi neza. Kugirango urusheho gukora neza, insinga za Cat6 ninzira isumba iyindi bitewe nubushakashatsi bwimbitse bwumuringa, butuma ubushyuhe bukwirakwizwa nubushobozi rusange mubikorwa bya PoE.

Umwanzuro

Mu gusoza, Imbaraga hejuru ya Ethernet (PoE) nigisubizo gihindura umukino cyoroshya itangwa ryamashanyarazi kubikoresho byurusobe mugihe byongera imikorere yabyo no kwishyira hamwe mubikorwa remezo bihari. Mugihe ikoranabuhanga rikomeje gutera imbere, PoE ikomeza kuba umukinnyi wingenzi mubikoresho bikoresha ingufu neza, bigira uruhare mubwenge buke kandi buhujwe nibidukikije bitandukanye. Mugusobanukirwa ubushobozi bwayo no gushyira mubikorwa byiza, abakoresha barashobora gukoresha neza inyungu zikoranabuhanga rishya.
