Isidibanisi se-RJ45 esikhuselekileyo: qinisekisa uqhagamshelwano olukhuselekileyo noluthembekileyo lwenethiwekhi
Ehlabathini lothungelwano, i-RJ45 ikhonkco iyinxalenye yendawo yonke edlala indima ebalulekileyo ekusekeni uxhulumaniso oluthembekileyo phakathi kwezixhobo. Nangona kunjalo, kwiindawo apho ukuphazamiseka kwe-electromagnetic interference (EMI) kunye nokuphazamiseka kwerediyo yerediyo (RFI) kuxhaphakile, iziqhagamshelo ezisemgangathweni ze-RJ45 zinokungaboneleli ngenqanaba lokhuseleko olufunekayo ukugcina ingqibelelo yesiginali. Kulapho iziqhagamshelo ze-RJ45 ezikhuselweyo zingena khona, zibonelela ngokhuseleko olwandisiweyo ngokuchasene nokuphazamiseka kwangaphandle kunye nokuqinisekisa uqhagamshelo lwenethiwekhi olukhuselekileyo noluthembekileyo.
Izixhumi ze-RJ45 ezikhuselweyo zenzelwe iindlela zokukhusela ezakhelwe ngaphakathi ukukhusela i-EMI kunye ne-RFI ekuphazamiseni ukuhanjiswa kwedatha kunye nokwenzakalisa ukusebenza kwenethiwekhi. Ikhaka ngokuqhelekileyo lenziwe ngesinyithi, njenge-nickel okanye i-zinc, kwaye idibaniswe kwizindlu zokudibanisa, yenza igobolondo ekhuselayo ejikeleze i-wiring yangaphakathi. Olu khuselo lunciphisa ngempumelelo impembelelo yokuphazamiseka kwangaphandle, ukuvumela ukuhanjiswa kwedatha okungaguqukiyo, okungaphazamisekiyo.
Enye yeenzuzo eziphambili zokusebenzisa izixhumi ze-RJ45 ezikhuselekileyo kukukwazi ukugcina ingqibelelo yesignali kwiindawo eziphezulu zengxolo. Kwiindawo zoshishino, amaziko edatha, kunye nezinye iindawo apho izixhobo zombane kunye noomatshini banokuvelisa i-EMI ebalulekileyo, izixhumanisi ezikhuselekileyo zibalulekile ekuqinisekiseni ukuba unxibelelwano lwenethiwekhi luhlala luzinzile kwaye luthembekile. Izixhumi ze-RJ45 ezikhuselweyo zinciphisa impembelelo yokuphazamiseka kwangaphandle, ukunceda ukuthintela iimpazamo zedatha, ukuthotywa kwesignali kunye nexesha lokunciphisa inethiwekhi.
Ukongeza, ukukhusela izixhumi ze-RJ45 kunceda ukugcina ukhuseleko lwenethiwekhi. Ukukhusela akuthinteli kuphela ukuphazamiseka kwangaphandle, kukwanceda ukuthintela ukuvalelwa komqondiso kunye nokufikelela okungagunyaziswanga kwiidatha ezibuthathaka. Oku kubaluleke kakhulu kwiindawo apho ukugcinwa kwedatha kunye nokhuseleko kubaluleke kakhulu, njengamaziko emali, ii-arhente zikarhulumente, kunye nezibonelelo zempilo.
Xa uhambisa izixhumi ze-RJ45 ezikhuselekileyo, kubalulekile ukuqinisekisa ukuba yonke isiseko senethiwekhi yenzelwe ukuxhasa ukusetyenziswa kwayo. Oku kubandakanya ukusebenzisa iintambo ezikhuselweyo kunye nokuqinisekisa ukumiselwa komhlaba okufanelekileyo ukwandisa ukusebenza kakuhle kwekhuselo. Ukongezelela, ukuhambelana nezixhobo zenethiwekhi kunye nokuthotyelwa kwemigangatho yoshishino yingqwalasela ebalulekileyo xa ukhetha izixhumi ze-RJ45 ezikhuselekileyo kwisicelo esithile.
Isishwankathelo, izixhumi ze-RJ45 ezikhuselweyo ziyinxalenye ebalulekileyo ekuqinisekiseni ukuthembeka, ukuthembeka, kunye nokhuseleko loqhagamshelwano lwenethiwekhi, ngakumbi kwiindawo apho i-EMI kunye ne-RFI zixhaphake. Ngokubonelela ngokhuseleko oluqinileyo ngokuchasene nokuphazamiseka kwangaphandle, ezi ziqhagamshelo zidlala indima ebalulekileyo ekugcineni ukusebenza kakuhle kwenethiwekhi kunye nokukhusela idatha ebuthathaka. Nokuba imeko yeshishini, yezorhwebo okanye yeshishini, ukusetyenziswa kweziqhagamshelo ezikhuselweyo ze-RJ45 linyathelo elisebenzayo lokunciphisa iingozi ezinxulumene nokuphazamiseka kombane kunye nokuqinisekisa ukusebenza kakuhle kweziseko zonxibelelwano zothungelwano.
