Imodyuli ye-optical sisixhobo sokuguqula isignali yombane, enokuthi ifakwe kwisixhobo se-transceiver yesignali yenethiwekhi ezifana neerotha, iiswitshi, kunye nezixhobo zothumelo. Zombini iimpawu zombane kunye nezamehlo zizibonakaliso zamaza omlingo. Uluhlu lothumelo lwemiqondiso yombane lim...

Kuluntu lwanamhlanje, i-Intanethi ingene kuzo zonke iinkalo zobomi bethu, apho inethiwekhi eneengcingo kunye neenethiwekhi ezingenazintambo zezona ziqhelekileyo. Okwangoku, eyona nethiwekhi yentambo idumileyo yi-Ethernet. Kodwa ngophuhliso lwetekhnoloji, iinethiwekhi ezingenazingcingo zingena nzulu kubomi bethu...

Ii-VLAN ezimileyo zikwabizwa ngokuba zii-VLAN ezisekwe kwizibuko. Oku kukuchaza ukuba leliphi izibuko leliphi i-VLAN ID. Ukusuka kwinqanaba lomzimba, ungacacisa ngokuthe ngqo ukuba i-LAN efakiweyo ihambelana ngqo nezibuko. Xa umlawuli weVLAN eqala ukuqwalasela ubudlelwane obuhambelanayo phakathi...

Ukuba awuwazi umahluko phakathi kwe-EPON Vs GPON kulula ukubhideka ngelixa uthenga. Ngeli nqaku masifunde ukuba yintoni i-EPON, yintoni i-GPON, kwaye yeyiphi ekufuneka iThengwe? Yintoni i-EPON? Inethiwekhi ye-Ethernet ye-passive ye-optical yifomu epheleleyo ye-acronym ...

Sonke siyazi ukuba kwi-LAN enye, uxhulumaniso lwehabhu luya kudala i-domain yengxabano. Ngelixa phantsi kokutshintsha, i-domain yengxabano ingasonjululwa, kuya kubakho indawo yosasazo. Ukuze ucombulule lo mmandla wosasazo, kuyimfuneko ukwazisa ii-routers ukwahlula iiLAN ezahlukeneyo kwiintlobo ezahlukeneyo...

Kwinkqubo yokuhanjiswa kwenethiwekhi, ukuba zonke ii-hubs zisetyenziswa. Kuqinisekile ukuba kwinkqubo yothumelo, kuba imiqondiso emininzi kufuneka isasazwe, i-domain yongquzulwano iya kuveliswa. Ngeli xesha, unxibelelwano phakathi kwemiqondiso luya kuphazamiseka kakhulu, kwaye izixhobo kwi-s...
