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...

I-antenna iyisisetshenziswa esingenzi lutho, esithinta kakhulu amandla e-OTA, ukuzwela, ububanzi bokuhlanganisa kanye nebanga, kuyilapho i-OTA iyindlela ebalulekile yokuhlaziya nokuxazulula inkinga yokuphuma. Imvamisa, sikala i-antenna ngokwemibandela elandelayo (ukusebenza kuzophinde kuthinte i...

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...

Igama eligcwele lemojula ye-optical i-optical transceiver, okuyithuluzi elibalulekile ohlelweni lokuxhumana lwe-fiber optical. Inesibopho sokuguqula isignali yokubona eyamukelwe ibe isignali kagesi, noma ukuguqula isignali kagesi yokufaka ...
