Imizila ihlukaniswa yaba izinhlobo ezintathu: umzila omile, umzila oguquguqukayo, nomzila oqondile. Endleleni yokufaka umzila omile owenziwe ngesandla, ukuze kuxazululwe inkinga yomzila wawo wonke umhlaba we-ip, ibuthakathaka kakhulu eqinisweni. Ngakho-ke, ochwepheshe bacabange ukuvumela irutha ukusuka ekhaya, itshele abaseduze...

I-VPN ubuchwepheshe bokufinyelela kude, okusho nje ukusebenzisa isixhumanisi senethiwekhi yomphakathi (imvamisa i-inthanethi) ukuze umise inethiwekhi yangasese. Isibonelo, ngolunye usuku umphathi ukuthumele ohambweni lwebhizinisi endaweni lapho ufuna ukufinyelela khona inethiwekhi yangaphakathi yeyunithi, lokhu kufinyelela kuwukufinyelela okukude. Ho...

I-Multiprotocol Label Switching (MPLS) ubuchwepheshe obusha benethiwekhi ye-IP backbone. I-MPLS yethula umqondo wokushintsha ilebula egxile ekuxhumekeni kumanethiwekhi e-IP angaxhumekile, futhi ihlanganisa ubuchwepheshe bomzila we-Layer-3 nobuchwepheshe bokushintsha i-Layer-2, okunikeza ukudlala okugcwele ekuguquguqukeni komzila we-IP...

Inethiwekhi yokufinyelela okubonakalayo (okungukuthi, inethiwekhi yokufinyelela enokukhanya njengendlela yokudlulisa, esikhundleni sezintambo zethusi, isetshenziselwa ukufinyelela umndeni ngamunye. Inethiwekhi yokufinyelela optical).Inethiwekhi yokufinyelela optical ngokuvamile iqukethe izingxenye ezintathu: optical line terminal OLT, optical network. iyunithi ONU, ukusabalalisa okubonakalayo...

Yini i-ONU? Namuhla, i-ONU empeleni ivame kakhulu ezimpilweni zethu. Uxhumano lwenethiwekhi olunikezwa u-opharetha olufakwe ekhaya lawo wonke umuntu lubizwa nge-Optical Modem, eyaziwa nangokuthi idivayisi ye-ONU. Inethiwekhi ka-opharetha ixhunywe kudivayisi yokubona, bese ixhunywa embobeni ye-PON ye...

Uma sikhetha imojuli ye-optical, ngaphezu kokupakishwa okuyisisekelo, ibanga lokudlulisela, nezinga lokudlulisela, kufanele futhi sinake izici ezilandelayo: 1. Izinhlobo zeFibre zohlobo lweFiber zingahlukaniswa zibe imodi eyodwa kanye nemodi eminingi. Amaza amaza amaphakathi wemodi yokubona eyodwa...
