Ezweni lanamuhla elisheshayo, lapho ukuxhumana kudlala indima ebalulekile kuzo zonke izici zempilo yethu, kubalulekile ukuba nezixazululo zenethiwekhi ezithembekile nezisebenza kahle ukuze kuhlangatshezwane nezidingo ezihlukahlukene zemindeni. Ngokufika kobuchwepheshe obuthuthukile obufana ne-CATV ONUs (Optical Network Units), sibona intuthuko ekuxhumekeni ekhaya. Kulo mbhalo webhulogi, sizongena emhlabeni othokozisayo we-CATV ONU, amakhono ayo, nokuthi ingaluguqula kanjani uxhumo lwasekhaya.
Kuhlanganiswe nobuchwepheshe be-dual-fiber three-wave:
I-CATV ONUyakhelwe kubuchwepheshe be-dual-fiber kanye ne-triple-wave ukuze kuqinisekiswe ukuxhumana kwe-inthanethi okuzinzile, okunesivinini esikhulu. Lobu buchwepheshe obusezingeni eliphezulu buhlanganisa amandla e-fiber optics ukudlulisa idatha, amasignali ezwi nevidiyo ngesikhathi esisodwa, okuhlinzeka abasebenzisi ngolwazi olungenazihibe, olungaphazamiseki ku-inthanethi.
IKomidi Eliphelele Lebhizinisi Lezokusakaza Nomabonakude le-FTTH:
Esinye sezici eziyinhloko ze-CATV ONU ibhodi layo lesevisi elididiyelwe, elingahlanganisa kalula umsakazo nethelevishini i-FTTH (fiber to the home) amasevisi. Ngalokhu kuhlanganiswa, abasebenzisi bangajabulela iziteshi zomsakazo neze-TV ezihlukahlukene kusukela ekunethezekeni kwamakhaya abo, bathuthukise ulwazi lwabo lokuzijabulisa. Ngokusebenzisa amandla okwamukela i-optical reception, i-CATV ONU iqinisekisa ukwamukela isignali engenasici kanye nokudluliselwa okungaphezu kwezixazululo zendabuko ezisekelwe ethusi.
I-Wi-Fi engenantambo kanye nomsebenzi wokwamukela ukukhanya kwe-CATV:
I-CATV ONU ihlanganisa i-WiFi engenantambo kanye namakhono okwamukela amehlo e-CATV ukuze idlule izixazululo zokuxhumana ezivamile. Lokhu kuhlanganiswa kwenza abasebenzisi bakwazi ukusetha kalula i-LAN yasekhaya (Inethiwekhi Yendawo Yendawo). I-CATV ONU ihlinzeka ngezindawo ezi-4 ze-Ethernet nokuxhumana kwe-WiFi okungenantambo, okuvumela amadivayisi amaningi ukuthi axhume futhi abelane ngezinsiza ngesikhathi esisodwa. Ukuthi usakaza amamuvi, imidlalo ye-inthanethi, noma usebenza usekhaya, i-LAN yasekhaya edalwe i-CATV ONU isiza ukuxhumana okungenazihibe nokwabelana kwedatha ekhaya.
Sekela ukusakazwa kwe-inthanethi nekhebula le-TV nezinsizakalo zikamabonakude:
Nge-CATV ONU, abasebenzisi abakwazi ukujabulela kuphela izinsiza ze-inthanethi ezingaphazamiseki, kodwa futhi bafinyelele ukusakazwa okukhulu kwe-CATV nokuqukethwe kukamabonakude. Ngokusebenzisa isixhumi esibonakalayo se-Ethernet kanye ne-WiFi engenantambo, i-CATV ONU yenza abasebenzisi bakwazi ukuphequlula i-inthanethi ngesivinini sombani nge-EPON (Ethernet Passive Optical Network). Ngesikhathi esifanayo, isamukeli sokukhanya se-CATV sithola amasiginali we-TV yedijithali ukuze kuqinisekiswe ukuthi abasebenzisi bathola ulwazi lwe-TV lwekhwalithi ephezulu, olunencazelo ephezulu. Ukuhlangana kwezinsizakalo ze-inthanethi nezekhebula ze-TV kuwubona ngempela umbono we-fiber-to-the-home (FTTH), ukunikeza abasebenzisi isixazululo esiphelele sokuxhuma.
Ngokufigqiwe:
Kafushane,I-CATV ONUubuchwepheshe bushintshe ngokuphelele ukuxhumana kwasekhaya ngokuhlanganisa ubuchwepheshe be-dual-fiber kanye namagagasi amathathu, amabhodi esevisi ahlanganisiwe, i-WiFi engenantambo kanye nemisebenzi yokwamukela optical ye-CATV. Lokhu okusha kuvula indlela yokuxhumana nokwabelana okungenazihibe ekhaya, ukuhlinzeka ngesevisi ye-inthanethi engaphazamiseki kanye nokusakaza ngekhebula elicebile nokuqukethwe kukamabonakude. Nge-CATV ONU, imindeni ingamukela ikusasa lokuxhumana futhi ijabulele i-inthanethi enesivinini esikhulu, ithelevishini enencazelo ephezulu kanye nokuzijabulisa okungenakuqhathaniswa.
