Umabonakude wekhebula ube yingxenye yempilo yethu amashumi eminyaka, unikeza ukuzijabulisa nolwazi emakhaya ethu.Kodwa-ke, ngokuthuthuka okusheshayo kobuchwepheshe, i-TV yekhebula yendabuko iyachithwa, futhi inkathi entsha iyeza.Ikusasa le-cable TV lisekuhlanganisweni kobuchwepheshe be-CATV ONU (Cable TV Optical Network Unit).
Ama-CATV ONU, aziwa nangokuthi amadivayisi we-fiber-to-the-home (FTTH), adlala indima ebalulekile ekuguquleni indlela ikhebula le-TV elethwa ngayo.Ubuchwepheshe buletha i-inthanethi enesivinini esikhulu, ithelevishini yedijithali kanye nezinsizakalo zezwi ngqo endaweni ehlala umsebenzisi ngezintambo ze-fiber optic.Ithathe indawo yekhebula le-coaxial yendabuko, yanikeza izinzuzo eziningi, futhi yavula indlela yenguquko embonini ye-cable TV.
Enye yezinzuzo eziyinhloko zeI-CATV ONUubuchwepheshe bungumkhawulokudonsa omangalisayo owuhlinzekayo.Izintambo ze-fiber optic zinamandla amakhulu futhi zingadlulisa idatha enkulu ngesivinini esimangalisayo.Ngokuhlanganisa ama-CATV ONU, abahlinzeki be-cable TV banganikeza iziteshi ze-UHD, izinsizakalo zokusakaza ezifunekayo, nezici ezisebenzisanayo ebezingacatshangwa ngaphambili.Ukuthuthuka komkhawulokudonsa kuqinisekisa umuzwa wokubuka ongenamthungo nothuthukisiwe wabathengi.
Ukwengeza, ubuchwepheshe be-CATV ONU abukhulisi nje kuphela izinga kanye nenani lamashaneli atholakalayo, kodwa futhi busekela izinketho zokwenza ngokwezifiso kanye nezakho.Ngokuhlanganiswa kokuxhuma ku-inthanethi, abathengi bangafinyelela inhlobonhlobo yezinhlelo zokusebenza, okuhlanganisa amapulatifomu evidiyo adingeka kakhulu, izinsiza zokusakaza kanye nokuqukethwe okusebenzisanayo.Lokhu kuvumela abasebenzisi ukuthi bakhethe ngokukhululekile ukuthi bafuna ukubuka ini futhi nini, ukushintsha ngokuphelele imodeli ye-TV yekhebula evamile.
Enye inzuzo ebalulekile yobuchwepheshe be-CATV ONU amandla ayo okonga izindleko.Izintambo ze-fiber optic zithembeke kakhulu futhi zidinga ukulungiswa okuncane kunezintambo zendabuko ze-coaxial.Ukuqina okwenyuka kwengqalasizinda kunciphisa isidingo sokulungiswa njalo nokushintshwa, kunciphisa izindleko kubahlinzeki bezintambo.Ngakho-ke, lokhu kongiwa kwezindleko kungadluliselwa ukuze kuzuze abathengi, okuholela ekuthengeni kwamaphakheji we-cable TV.
Ukwengeza, ubuchwepheshe be-CATV ONU buhlinzeka ngethuba kubahlinzeki be-cable TV ukuthi banikeze izinsizakalo ezihlanganisiwe.Ngokuhlanganiswa kwezinsizakalo zezwi kanye ne-inthanethi enesivinini esikhulu, abathengi bangahlangabezana nazo zonke izidingo zabo zokuxhumana nezokuzijabulisa ezivela kumhlinzeki oyedwa.Lokhu kuhlangana kwezinsizakalo kwenza ulwazi lomthengi lube lula futhi kususa ubunzima bokuphatha okubhaliselwe okuningi.
Ukwengeza, ukuqina nokuguquguquka kobuchwepheshe be-CATV ONU bukwenza kube ubufakazi besikhathi esizayo.Njengoba ubuchwepheshe buqhubeka buthuthuka, ukuhlanganiswa kwezici ezintsha namasevisi kungenamthungo ngamanethiwekhi e-fiber optic.Abahlinzeki be-Cable TV bangakwazi ukuzivumelanisa kalula nezidingo ezishintshayo zabathengi kanye nezintandokazi, baqinisekise ukuthi bahlala bencintisana futhi behamba phambili embonini.
Ukufingqa, ikusasa le-cable TV lisekuhlanganisweni kweI-CATV ONUubuchwepheshe.Lesi sixazululo esisha siguqula imodeli ye-TV yekhebula evamile, sinikeza umkhawulokudonsa othuthukisiwe, izinketho zokwenza ngokwezifiso nokonga kwezindleko.Ngokwamukela lobu buchwepheshe, abahlinzeki be-cable TV bangahlangabezana nesidingo sabathengi sokuqukethwe kwekhwalithi ephezulu, ukuzizwisa komuntu siqu kanye nezinsizakalo ezihlanganisiwe.Iminyaka yobuchwepheshe be-CATV ONU isifikile, ingenisa inkathi entsha yethelevishini yezintambo, iletha ikusasa eliqhakazile nelijabulisa kakhudlwana kubabukeli emhlabeni wonke.
