Ezweni lanamuhla elisheshayo, lapho ukuxhumana kudlala indima ebalulekile kuzo zonke izici zokuphila kwethu, kubalulekile ukuba nezixazululo zenethiwekhi ezithembekile nezisebenzayo ukuze kuhlangatshezwane nezidingo ezahlukahlukene zemindeni. Ngokufika kobuchwepheshe obuthuthukisiwe njenge-CATV ONUs (Optical Network Units), sibona intuthuko ethuthukisiwe ekuxhumekeni kwekhaya. Kulesi sihloko sebhulogi, sizohlola umhlaba ojabulisayo we-CATV ONU, amakhono ayo, nokuthi ingaguqula kanjani ukuxhumana kwekhaya.
Kuhlanganiswe nobuchwepheshe be-dual-fiber three-wave:
I-CATV ONUYakhelwe kubuchwepheshe be-dual-fiber kanye ne-triple-wave ukuqinisekisa ukuxhumana kwe-inthanethi okuzinzile, okusheshayo. Lobu buchwepheshe obusezingeni eliphezulu buhlanganisa amandla e-fiber optics ukudlulisa idatha, amasignali ezwi kanye nevidiyo ngasikhathi sinye, okunikeza abasebenzisi ulwazi olungenaziphazamiso ku-inthanethi.
IKomidi Lebhizinisi Eliphelele Lebhizinisi Lokusakaza Nokuthelevishini le-FTTH:
Esinye sezici eziyinhloko ze-CATV ONU yibhodi yayo yesevisi ehlanganisiwe, engahlanganisa kalula izinsizakalo zomsakazo nethelevishini ze-FTTH (fiber ekhaya). Ngale nhlanganisela, abasebenzisi bangajabulela iziteshi ezahlukene zomsakazo ne-TV besuka emakhaya abo, bathuthukise ulwazi lwabo lokuzijabulisa. Ngokusebenzisa amandla okwamukela okubonakalayo, i-CATV ONU iqinisekisa ukwamukelwa kwesignali okungenaphutha kanye nokudluliswa ngale kwezixazululo zendabuko ezisekelwe ethusi.
Umsebenzi wokwamukela ukukhanya kwe-WiFi okungenantambo kanye ne-CATV:
I-CATV ONU ihlanganisa i-WiFi engenantambo kanye namakhono okwamukela i-CATV ukuze idlule izixazululo zokuxhuma zendabuko. Lokhu kuhlanganiswa kwenza abasebenzisi bakwazi ukusetha kalula i-LAN yasekhaya (iNethiwekhi Yendawo Yendawo). I-CATV ONU inikeza izixhumi ze-Ethernet ezine kanye nokuxhumeka kwe-WiFi okungenantambo, okuvumela amadivayisi amaningi ukuxhuma nokwabelana ngezinsiza ngesikhathi esisodwa. Kungakhathaliseki ukuthi isakaza ama-movie, imidlalo eku-inthanethi, noma isebenza ekhaya, i-LAN yasekhaya eyenziwe yi-CATV ONU yenza kube lula ukuxhumana nokwabelana ngedatha ngaphakathi ekhaya.
Sekela izinsizakalo zokusakaza ze-inthanethi nezethelevishini zekhebula kanye nezinsizakalo zethelevishini:
Nge-CATV ONU, abasebenzisi abakwazi nje ukujabulela izinsizakalo ze-inthanethi ezingaphazanyiswa, kodwa futhi bangakwazi ukufinyelela okuqukethwe okukhulu kokusakazwa kwe-CATV kanye nethelevishini. Ngokusebenzisa isikhombimsebenzisi se-Ethernet kanye ne-WiFi engenantambo, i-CATV ONU ivumela abasebenzisi ukuthi baphequlule i-inthanethi ngesivinini sombani nge-EPON (Ethernet Passive Optical Network). Ngesikhathi esifanayo, isamukeli se-optical se-CATV sithola izimpawu ze-TV zedijithali ukuqinisekisa ukuthi abasebenzisi bathola ulwazi lwe-TV olusezingeni eliphezulu nolunencazelo ephezulu. Ukuhlangana kwezinsizakalo ze-inthanethi kanye ne-TV yekhebula kufeza ngempela umbono we-fiber-to-the-home (FTTH), okunikeza abasebenzisi ikhambi eliphelele lokuxhumana.
Ngokufigqiwe:
Kafushane,I-CATV ONUubuchwepheshe bushintshe ngokuphelele ukuxhumana kwasekhaya ngokuhlanganisa ubuchwepheshe be-dual-fiber kanye nobe-three-wave, amabhodi enkonzo ahlanganisiwe, i-WiFi engenantambo kanye nemisebenzi yokwamukela i-CATV optical. Lokhu kusungula izinto ezintsha kuvula indlela yokuxhumana okungenamthungo kanye nokwabelana ngaphakathi ekhaya, kuhlinzeka ngensizakalo ye-inthanethi engaphazanyiswa kanye nokuqukethwe okucebile kokusakazwa kwekhebula kanye nethelevishini. Nge-CATV ONU, imindeni ingamukela ikusasa lokuxhumana futhi ijabulele i-inthanethi esheshayo, ithelevishini esezingeni eliphezulu kanye nokuhlangenwe nakho kokuzijabulisa okungenakuqhathaniswa.
