Imojuli ye-optical iyidivayisi yokuguqula isignali yezithombe zikagesi, engafakwa kumpahla ye-transceiver yesignali yenethiwekhi njengamarutha, amaswishi, nezinto zokudlulisa. Kokubili amasignali kagesi kanye ne-optical amasignali amaza kazibuthe. Uhla lokudluliswa kwamasignali kagesi lim...

Emphakathini wanamuhla, i-inthanethi ingene kuzo zonke izici zempilo yethu, lapho inethiwekhi enezintambo namanethiwekhi angenawaya ajwayeleke kakhulu. Njengamanje, inethiwekhi yekhebula edume kakhulu yi-Ethernet. Kepha ngokuthuthuka kobuchwepheshe, amanethiwekhi angenawaya angena ekujuleni kwempilo yethu...

Ama-VLAN aqinile abizwa nangokuthi ama-VLAN asekelwe echwebeni. Lokhu okokucacisa ukuthi iyiphi imbobo okungeyayo i-VLAN ID. Kusukela ezingeni lomzimba, ungacacisa ngokuqondile ukuthi i-LAN efakiwe ihambisana nechweba ngokuqondile. Lapho umlawuli we-VLAN ekuqaleni elungiselela ubudlelwano obuhambisanayo phakathi...

Uma ungazi ngomehluko phakathi kwe-EPON Vs GPON kulula ukudideka ngenkathi uthenga. Ngalesi sihloko masifunde ukuthi iyini i-EPON, yini i-GPON, futhi iyiphi ongayithenga? Yini i-EPON? I-Ethernet passive optical network iwuhlobo olugcwele lwesifinyezo ...

Sonke siyazi ukuthi ku-LAN efanayo, ukuxhumeka kwehabhu kuzodala isizinda sokungqubuzana. Ngenkathi ingaphansi koshintsho, isizinda sokungqubuzana singaxazululwa, kuzoba nesizinda sokusakaza. Ukuze uxazulule lesi sizinda sokusakaza, kuyadingeka ukwethula amarutha ukuze ahlukanise ama-LAN ahlukene abe...

Enqubweni yokudlulisa inethiwekhi, uma wonke amahabhu asetshenziswa. Kuqinisekile ukuthi ohlelweni lokudlulisela, ngenxa yokuthi amasignali amaningi kakhulu adinga ukusakazwa, isizinda sokungqubuzana sizokwenziwa. Ngalesi sikhathi, ukuxhumana phakathi kwamasignali kuzophazamiseka kakhulu, futhi amadivaysi ku-s...
