I-RJ-45 PoE: Ukunika amandla uQhagamshelwano lwakho lwe-Ethernet
2024-04-21 17:47:29
I-port ye-RJ-45 Ethernet yi-interface ebonakalayo eyenza udibaniso lwezixhobo zothungelwano zisebenzisa iintambo ezijijekileyo. Yenzelwe ukuhlalisa iingcingo ezisibhozo, ezisetyenziselwa ukuthumela nokwamkela idatha. Izibuko liqhele ukufunyanwa ngasemva kwisixhobo sothungelwano kwaye lisetyenziselwa ukuseka uqhagamshelo olunentambo kwinethiwekhi yendawo yendawo (LAN) okanye i-intanethi.
Amandla phezu kwe-Ethernet (PoE) iteknoloji evumela ukuhanjiswa kwedatha ngaxeshanye kunye namandla ombane kwikhebula le-Ethernet elifanayo. Oku kuyenzeka ngokusebenzisa iingcingo ezingasetyenziswanga kwintambo ye-Ethernet ukuthwala amandla ombane, ukuphelisa imfuno yentambo yamandla eyahlukileyo. Izixhobo ezixhasa i-PoE zinokunikwa amandla ngokuthe ngqo kwi-port ye-Ethernet, ukwenza lula ukufakela kunye nokunciphisa imfuno yombane ongezelelweyo.
Xa kuziwa kwi-RJ-45 PoE, i-port ye-Ethernet ayisebenzisi kuphela ukuhanjiswa kwedatha kodwa kunye nokuhambisa amandla kwizixhobo ezihambelanayo. Oku kubaluleke kakhulu kwizixhobo ezifana neekhamera ze-IP, iindawo zokungena ezingenazingcingo, kunye neefowuni zeVoIP, ezinokuthi zinikwe amandla ngokufanelekileyo usebenzisa intambo ye-Ethernet enye. I-RJ-45 PoE isemgangathweni phantsi kwe-IEEE 802.3af kunye ne-IEEE 802.3at, echaza iinkcukacha zobugcisa bokuhambisa amandla phezu kwe-Ethernet.
Xa idityaniswe neteknoloji ye-PoE, iba lujongano oluguquguqukayo olunokuthi kwakhona lunikeze amandla kwizixhobo ezihambelanayo, ukwenza lula ukufakela kunye nokunciphisa i-clutter yentambo. Nokuba useka inethiwekhi yekhaya okanye isiseko sorhwebo, i-RJ-45 PoE ibonelela ngesisombululo esiluncedo nesisebenzayo sokunika amandla izixhobo zakho eziqhagamshelwe kwi-Ethernet.
