Mphamvu pa teknoloji ya Ethernet (PoE) imathandiza kuti zipangizo zamakono za Ethernet zitha kugwira ntchito ngati zingwe zamagetsi. Mu makina ovomerezeka a PoE, magetsi amodzi omwe amagwiritsira ntchito magetsi (DC) amayenderera pa chingwe chachingwe pamodzi ndi maulendo achidziwitso a Ethernet. Makina ambiri a APE amatsatira IEEE 802.3af kapena 802.3at .
Mphamvu pa Ethernet inapangidwa kuti igwiritsidwe ntchito ndi zipangizo zamakono zogwiritsa ntchito mafoni monga ma Wi-Fi (APs) , ma webcams, ndi mafoni a VoIP . PoE amalola zipangizo zamagetsi kuti ziyike muzitsulo kapena malo ozungulira kumene magetsi sangakwanitse.
Katswiri wamakina osagwirizana ndi mizere ya PoE, Ethernet pa magetsi amapangitsa mizere yowonjezera yamagetsi kugwiritsira ntchito mautumiki akutali akutali a Ethernet.
Chifukwa Chake Ma Network Home Amagwiritsira Ntchito Mphamvu pa Ethernet
Chifukwa chakuti nyumba zambiri zimakhala ndi malo ambiri ogulitsira magetsi komanso zochepa zojambula zamakoma a Ethernet, ndipo zipangizo zamagetsi zambiri zimagwiritsa ntchito ma Wi-Fi m'malo mwa Ethernet, ntchito za PoE zochezera kunyumba zimakhala zochepa. Ogulitsa pafupipafupi amangophatikizapo chithandizo cha PoE pamasitomala awo apamwamba komanso otchuka komanso magetsi chifukwa cha izi.
Ogulitsa DIY akhoza kuwonjezera PoE chithandizo ku kugwirizana kwa Ethernet pogwiritsa ntchito chipangizo chochepa ndi chotchipa chotchedwa PoE injector. Zida zimenezi zimaphatikizapo mautchi a Ethernet (ndi adapala) omwe amalola makina oyenera Ethernet ndi mphamvu.
Kodi Mitundu Yotani Imagwira Ntchito ndi Mphamvu pa Ethernet?
Mtengo wa mphamvu (mu watts) umene ungaperekedwe pa Ethernet uli wochepa ndi teknoloji. Mphamvu yeniyeni ya mphamvu yofunikira imadalira kuwerengedwa kwa madzi otsika kuchokera ku gwero la PoE ndi kukopa kwa magetsi a makasitomala. IEEE 802.3af, mwachitsanzo, imatsimikizira 12.95W okha mphamvu pa mgwirizano wapatsidwa. Ma PC apamwamba ndi makapu ambiri sangathe kugwira ntchito poE chifukwa cha zosowa zawo zapamwamba (makamaka 15W ndi pamwamba), koma zipangizo zamakono monga makompyuta omwe amagwira ntchito osachepera 10W angathe. Nthawi zina amalonda amalumikiza poE poe yomwe gulu la ma webcams kapena zipangizo zofanana zimagwirira ntchito.
