Indlela Umxhasi womnxeba osebenzayo
IJack 45 ebhalisiweyo (RJ45) luhlobo olusisigxina lomnxibelelwano womzimba kwizixhobo zenethiwekhi. Izixhumo ze-RJ45 ziyabonakala ngokuqhelekileyo ngeetambo ze- Ethernet kunye namanethiwekhi.
Iikhowudi ze-Ethernet zanamhlanje ziquka iplastiki encinane kwiphepha ngalinye elifakwe kwiikhomputha ze-RJ45 ze-Ethernet. Igama elithi "iplagi" libhekisela kumgca okanye "endodeni" ekupheleni kokuqhagamshelana ngelixa igama elithi "jack" libhekisela kwisibini okanye ekupheleni kwe "wesifazane".
RJ45, RJ45s, kunye ne-8P8C
Iiprogigi ze-RJ45 zibonisa izikhonkwane ezisibhozo apho i-wire strands ye-cable interface isebenza ngombane. Iplagi nganye ineendawo ezisibhozo ezihlukeneyo malunga ne-1 mm ngaphandle apho iifowuni zodwa zifakwe khona zixhobo ezikhethiweyo zokubethela i-cable. 8P8C, i-shorthand ye-Eight position, UQhagamshelwano lwesibhozo).
Iikhompyutha ze-Ethernet kunye ne-8P8C kufuneka zifakwe kwi-RJ45 iphethini yocingo ukuze isebenze ngokufanelekileyo. Ngokwenene, i-8P8C ingasetyenziswa kunye nezinye iintlobo zonxibelelwano ngaphandle kwe-Ethernet; ikwasetyenziswa kwakhona ngee - serial RS-232 , umzekelo. Nangona kunjalo, ngenxa yokuba i-RJ45 yindlela ephezulu kakhulu yokusetyenziswa kwe-8P8C, abaqeqeshi bezoshishino bavame ukusebenzisa le mibini emibini.
Iimodemu zokudibanisa zemveli zasebenzisa ukuhluka kwe-RJ45 ebizwa ngokuba yi-RJ45 , ebonisa oomnxibelelwano ababini kuphela kwi-8P2C yokucwangcisa esikhundleni sesibhozo. Ukufana okusemgangathweni kwe-RJ45 kunye ne-RJ45 kwenza kube nzima ukuba ilanga elingakhange lifundiswe ukuba lichaze le mibini.
Ukuxhamla kwi-Wiring ye-RJ45 Connectors
Iifayile ezimbini eziqhelekileyo ze-RJ45 zichaza ukulungiswa kwezicingo ezisibhozo ezifunekayo xa zidibanisa ukuxhuma kwikhebula: imigangatho ye- T568A kunye ne- T568B . Bobabini ba landela iindibano zokugaya iintambo ngamanye amahlanu emibala-ebomvu, eluhlaza, e-orange, eluhlaza okwesibhakabhaka, okanye emhlophe-kunye nemigca ethile kunye nokudibanisa okuqinile.
Ukulandela ezi ngqungquthela kubalulekile xa ukwakha izintambo ukuqinisekisa ukuhambelana kombane nezinye izixhobo. Ngezizathu zembali, i-T568B ibe yinto eyaziwayo kakhulu. Itheyibhile ingezantsi ifingqa le khowudi yokubhala.
| Iphoyinti | T568B | T568A |
|---|---|---|
| 1 | umhlophe ngomgca welalanti | emhlophe ngomgca ohlaza |
| 2 | orenji | luhlaza |
| 3 | umgca ohlaza | umhlophe ngomgca welalanti |
| 4 | luhlaza | luhlaza |
| 5 | emhlophe ngemigca eluhlaza | emhlophe ngemigca eluhlaza |
| 6 | luhlaza | orenji |
| 7 | umhlophe ngomgca omnyama | umhlophe ngomgca omnyama |
| 8 | ntsundu | ntsundu |
Ezinye iindidi ezinxibelelwano zifana ne-RJ45, kwaye zinokudideka kalula. Izixhumo ze-RJ11 ezisetyenziswe ngetambo zefowuni, umzekelo, sebenzisa izixhumo zesikhundla sixhenxe kunokuba zixhomekeke kwizixhumi zesikhundla, zibenze zibe ziincinci kunezixhobo ze-RJ45.
Imiba eneRJ45
Ukwenza uxhumano oluqinileyo phakathi kweplagi kunye ne-port network, ezinye iiprogi ze-RJ45 zisebenzisa iplastiki encinci, ekhohlakeleyo ebizwa ngokuba yi-tab. Ithebhu yenza uphawu oluqinileyo phakathi kwekhebula kunye nefowuni ekufakeni, efuna umntu ukuba enze isicelo sengcinezelo esezantsi kwisithuba sokuvumela ukukhutshwa. Oku kunceda ukukhusela ikhebula ekuphumeni ngokungahambi. Ngelishwa, la mathubhu aphuka kalula xa ebuyela emuva, okwenzekayo xa umnxibelelwano unqamle kwelinye ikhebula, impahla okanye enye into esondeleyo.
