Ukuqonda isiqhagamshelo se-RJ45: Umqolo weeNethiwekhi ezineNcingo!
Ngena kwihlabathi lothungelwano lwe-Ethernet kunye nesikhokelo esibanzi kwi-RJ45 isinxibelelanisi, isakhiwo sayo, kunye nendima yayo ebalulekileyo ekuhanjisweni kwedatha ngesantya esiphezulu.
I-Ethernet kunye neMigangatho ye-RJ:
Itekhnoloji ye-Ethernet yenza unxibelelwano olungenamthungo phakathi kwezixhobo ezininzi ngaphakathi kwenethiwekhi, elawulwa ziiprothokholi ezithile eziqinisekisa unxibelelwano olusebenzayo. IiJacks ezibhalisiweyo (i-RJ) zilungelelwaniso lojongano lomzimba olulungiselelwe uthungelwano lweendaba ezahlukeneyo. Phakathi kwazo, i-RJ45, i-RJ11, i-RJ48, kunye ne-RJ61 zixhaphakile, nganye ilungiselelwe usetyenziso olwahlukileyo ngaphakathi kwenethiwekhi ye-Ethernet.
Isidibanisi se-RJ45:
Isidibanisi se-RJ45, esibizwa ngokusemthethweni njenge-Registered Jack 45, ibe ngumgangatho we-de facto woqhagamshelo lwenethiwekhi enentambo. Iqale yaphuhliswa kwiinkqubo zefowuni, ukusukela oko yavela ukuba ibe yindawo yonke kuthungelwano lwe-Ethernet. I-“45″ kwi-RJ45 ibonisa uluhlu lwayo olulodwa phakathi kweenkcukacha zejack ezibhalisiweyo.
IiNgcaciso zobuGcisa:
Ibonakaliswe ngefomu yayo enkulu xa kuthelekiswa neentambo zomnxeba, i-RJ45 ikhonkco ithatha i-bandwidth ebanzi, ngokuqhelekileyo ifikelela kwi-10 Gbps. Esi sixhobo sinesantya esiphezulu, sidityaniswe neempawu zokhuseleko ezongeziweyo, zibeka i-RJ45 njengesidibanisi esikhethwayo sokudibanisa iikhomputha zobuqu kwiiseva, iirotha, kunye nezinye iziseko zenethiwekhi.
Ukuqulunqwa koLwakhiwo:
Umdibaniso we-RJ45 uqhayisa ukucwangciswa kwe-8-pin, ebizwa ngokusemthethweni njenge-8P8C, evumela ukudibanisa kweengcingo ezisibhozo. Ngokuqhelekileyo idibaniswe kunye neShielded Twisted Pair (STP) okanye i-Unshielded Twisted Pair (UTP) iintambo, i-RJ45 ikhonkco yeplastiki yeplastiki ecacileyo inika umbono ocacileyo we-wiring yangaphakathi.
ImiGangatho yeeNcingo:
Xa ujongisisa, umntu unokubona iingcingo ezisibhozo ezihlukeneyo ngaphakathi kwesinxibelelanisi se-RJ45, esahlulwe ngemibala eyomeleleyo nenemigca. I-RJ45 i-wiring ihlelwe ngokusekelwe ekusebenzeni kwayo, kunye neendidi ezifana ne-Cat 5e, i-Cat 6, kunye ne-Cat 7, nganye inikezela ngamanqanaba ahlukeneyo okuhanjiswa komgangatho kunye ne-bandwidth.
Ukukhowudwa koMbala kunye neMigangatho:
Ikhowudi yombala yeengcingo ze-RJ45 zisemgangathweni ukuze kube lula ukuchongwa kunye nokudibanisa. Iikhowudi ezimbini eziphambili zekhowudi yemibala zikhona: T568A kunye ne-T568B. Umgangatho we-T568A ubeka iingcingo eziluhlaza phambi kweorenji, ngelixa i-T568B ibuyisela umva lo myalelo. I-T568A iqinisekisa ukuhambelana nokubuyela ngasemva kunye neenkqubo zocingo zelifa, ngelixa i-T568B iyilelwe ukunciphisa ingxolo yomqondiso, iphucula ukuhanjiswa kwedatha imfezeko.
