Ƙarfin POE akan kariyar hawan Ethernet

Haɓaka fasahar Power over Ethernet (POE) tana da ƙarfi sosai.Haɓaka wannan fasaha na iya sauƙaƙe shigarwa da ƙaddamar da kayan aikin lantarki, don haka kawar da buƙatar hanyoyin sadarwa masu zaman kansu.A zamanin yau, ana amfani da fasahar samar da wutar lantarki (POE) sosai a cikin tsarin masana'antu kamar tsaro, sadarwa, da grid mai wayo don cimma bayanai, watsa bidiyo, sarrafa kwarara, da samar da wutar lantarki ta hanyar bas a cikin tsarin.Koyaya, saboda matsanancin yanayin aiki na Ethernet Industrial, haɓakawa da kariyar kariyar tashar POE yana da mahimmanci.Anan ga taƙaitaccen gabatarwa ga tsarin kariya na tsarin POE:
