Isixhumi esivikelekile se-RJ45: qinisekisa ukuxhumana kwenethiwekhi okuphephile nokuthembekile
Emhlabeni wokuxhumana, isixhumi se-RJ45 siyingxenye yonke indawo edlala indima ebalulekile ekusunguleni ukuxhumana okuthembekile phakathi kwamadivayisi. Kodwa-ke, ezindaweni lapho ukuphazamiseka kwe-electromagnetic (EMI) kanye nokuphazamiseka kwefrikhwensi yomsakazo (RFI) kwandile, izixhumi ezijwayelekile ze-RJ45 zingase zinganikezi izinga lokuvikela elidingekayo ukuze kugcinwe ubuqotho besignali. Yilapho izixhumi ze-RJ45 ezivikelwe ziqala ukusebenza khona, zinikeze isivikelo esithuthukisiwe ekuphazamisekeni kwangaphandle kanye nokuqinisekisa ukuxhumana kwenethiwekhi okuphephile nokuthembekile.
Izixhumi ezivikelwe ze-RJ45 ziklanywe ngendlela yokuvikela eyakhelwe ngaphakathi ukuze kuvinjelwe i-EMI ne-RFI ekuphazamiseni ukudluliswa kwedatha kanye nokulimaza ukusebenza kwenethiwekhi. Isihlangu ngokuvamile senziwe ngensimbi, njenge-nickel noma i-zinc, futhi sihlanganiswe nendlu yesixhumi, senze igobolondo elivikelayo elizungeze izintambo zangaphakathi. Lokhu kuvikela kunciphisa ngempumelelo umthelela wokuphazamiseka kwangaphandle, okuvumela ukudluliswa kwedatha okungaguquki, okungaphazamiseki.
Enye yezinzuzo eziyinhloko zokusebenzisa izixhumi ze-RJ45 ezivikelekile yikhono lokugcina ubuqotho besignali ezindaweni ezinomsindo omkhulu. Ezindaweni zezimboni, izikhungo zedatha, nezinye izindawo lapho okokusebenza kukagesi nemishini kungakha i-EMI ebalulekile, izixhumi ezivikelekile zibalulekile ekuqinisekiseni ukuthi ukuxhumana kwenethiwekhi kuhlala kuzinzile futhi kuthembekile. Izixhumi ezivikelekile ze-RJ45 zinciphisa umthelela wokuphazamiseka kwangaphandle, okusiza ukuvimbela amaphutha edatha, ukuwohloka kwesignali kanye nokuphelelwa yisikhathi kwenethiwekhi okungaba khona.
Ngaphezu kwalokho, ukuvikela izixhumi ze-RJ45 nakho kusiza ekugcineni ukuphepha kwenethiwekhi. Ukuvikela akuvimbeli kuphela ukuphazamiseka kwangaphandle, futhi kusiza ukuvimbela ukulalela isignali nokufinyelela okungagunyaziwe kudatha ebucayi. Lokhu kubaluleke kakhulu ezindaweni lapho ukugcinwa kuyimfihlo kwedatha nokuvikeleka kubaluleke kakhulu, njengezikhungo zezezimali, izikhungo zikahulumeni, nezikhungo zokunakekelwa kwempilo.
Lapho kuthunyelwa izixhumi ezivikelekile ze-RJ45, kubalulekile ukuqinisekisa ukuthi yonke ingqalasizinda yenethiwekhi iklanyelwe ukusekela ukusetshenziswa kwayo. Lokhu kuhlanganisa ukusebenzisa izintambo ezivikelekile kanye nokuqinisekisa ukubeka phansi okufanele ukuze kukhuliswe ukusebenza kahle kokuvikela. Ukwengeza, ukuhambisana nemishini yenethiwekhi nokuhambisana nezindinganiso zomkhakha kuwukucatshangelwa okubalulekile lapho kukhethwa izixhumi ze-RJ45 ezivikelwe zohlelo oluthile.
Kafushane, izixhumi ze-RJ45 ezivikelekile ziyingxenye ebalulekile ekuqinisekiseni ubuqotho, ukwethembeka, nokuvikeleka kokuxhumeka kwenethiwekhi, ikakhulukazi ezindaweni lapho i-EMI ne-RFI zivame khona. Ngokuhlinzeka ngokuzivikela okuqinile ngokumelene nokuphazamiseka kwangaphandle, lezi zixhumi zidlala indima ebalulekile ekugcineni ukusebenza kwenethiwekhi okuseqophelweni eliphezulu nokuvikela idatha ebucayi. Kungakhathaliseki ukuthi kusendaweni yezimboni, ezentengiselwano noma zebhizinisi, ukusetshenziswa kwezixhumi ezivikelwe ze-RJ45 kuyisinyathelo esisheshayo sokunciphisa ubungozi obuhlobene nokuphazamiseka kazibuthe kagesi kanye nokuqinisekisa ukusebenza kahle kwengqalasizinda yenethiwekhi.
