Umabonakude wecable uyinxalenye yobomi bethu amashumi eminyaka, ubonelela ngokonwabisa kunye nolwazi kumakhaya ethu.Nangona kunjalo, ngenkqubela phambili ekhawulezileyo yetekhnoloji, iTV yentambo yesiko iyathotywa, kwaye ixesha elitsha liyeza.Ikamva le-TV ye-cable ilele ekudityanisweni kwe-CATV ONU (i-Cable TV Optical Network Unit) ubuchwepheshe.
I-CATV ONUs, eyaziwa ngokuba yi-fiber-to-the-home (FTTH) izixhobo, zidlala indima ebalulekileyo ekutshintsheni indlela yokuhanjiswa kwe-cable TV.Itekhnoloji izisa i-Intanethi enesantya esiphezulu, umabonakude wedijithali kunye neenkonzo zelizwi ngokuthe ngqo kwindawo yokuhlala yomsebenzisi ngeentambo zefiber optic.Yathatha indawo yentambo ye-coaxial yesiko, yabonelela ngeenzuzo ezininzi, kwaye yavula indlela yoguquko kushishino lwentambo yeTV.
Enye yeenzuzo eziphambili zeCATV ONUitekhnoloji yi-bandwidth engakholelekiyo ebonelela ngayo.Iintambo zeFiber optic zinomthamo ongaqhelekanga kwaye zinokudlulisela amanani amakhulu edatha ngesantya esimangalisayo.Ngokudibanisa ii-CATV ONUs, ababoneleli beTV beTV banokunikezela ngeziteshi ze-UHD, iinkonzo zokusasaza ezifunwayo, kunye neempawu ezisebenzisanayo ebezingenakucingelwa ngaphambili.Inkqubela phambili kwi-bandwidth iqinisekisa amava okujonga angenamthungo kunye nokuphuculwa kwabathengi.
Ukongeza, itekhnoloji yeCATV ONU ayinyusi nje kuphela umgangatho kunye nobuninzi bamajelo akhoyo, kodwa ikwaxhasa iinketho zokwenza ngokwezifiso kunye nezomntu.Ngokudityaniswa konxibelelwano lwe-Intanethi, abathengi banokufikelela kuluhlu olubanzi lwezicelo, kubandakanya iiplatifti zevidiyo-kwimfuno, iinkonzo zokusasaza kunye nomxholo osebenzisanayo.Oku kuvumela abasebenzisi ukuba bakhethe ngokukhululekileyo ukuba yintoni na xa befuna ukubukela, betshintsha ngokupheleleyo imodeli yeTV yendabuko.
Olunye uncedo olubalulekileyo lwe-CATV ONU yetekhnoloji yikhono layo lokonga iindleko.Iintambo ze-Fiber optic zithembeke ngakumbi kwaye zifuna ukulungiswa okuncinci kuneentambo ze-coaxial zendabuko.Ukonyuka kokuqina kweziseko ezingundoqo kunciphisa imfuno yokulungiswa rhoqo kunye nokutshintshwa, ukunciphisa iindleko kubaboneleli beekhebula.Ngoko ke, oku kongiwa kweendleko kunokudluliselwa kwinzuzo yabathengi, okukhokelela kwiiphakheji ezifikelelekayo ze-cable TV.
Ukongeza, iteknoloji yeCATV ONU inika ithuba lokuba ababoneleli beTV babonelele ngeenkonzo ezidityanisiweyo.Ngokudityaniswa kweenkonzo zelizwi kunye nesantya esiphezulu se-Intanethi, abathengi banokuhlangabezana nazo zonke iimfuno zabo zonxibelelwano kunye nokuzonwabisa kumnikezeli omnye.Oku kudityaniswa kweenkonzo kwenza lula amava omthengi kwaye kususa ingxaki yokulawula imirhumo emininzi.
Ukongezelela, ukulinganisa kunye nokuguquguquka kweteknoloji yeCATV ONU yenza ukuba kube bubungqina bexesha elizayo.Njengoko itekhnoloji iqhubeka nokuhambela phambili, ukudityaniswa kweempawu ezintsha kunye neenkonzo ziba zingenamthungo ngothungelwano lwefiber optic.Ababoneleli be-Cable TV banokuziqhelanisa ngokulula nokutshintsha iimfuno zabathengi kunye nezinto abazithandayo, baqinisekise ukuba bahlala bekhuphisana kwaye bephambili kwishishini.
Ukushwankathela, ikamva le-TV yentambo ilele ekudityanisweni kweCATV ONUiteknoloji.Esi sicombululo sitshintsha imodeli yeTV yentambo yesiqhelo, inikezela ngebhanwidth eyongeziweyo, iinketho zokwenza ngokwezifiso kunye nokonga iindleko.Ngokwamkela le teknoloji, ababoneleli beTV banokuhlangabezana nemfuno yabathengi kumxholo ophezulu, amava omntu kunye neenkonzo ezihlanganisiweyo.Ixesha lobuchwephesha beCATV ONU lifikile, lingenisa ixesha elitsha likamabonakude wentambo, izisa ikamva eliqaqambileyo nelinika umdla kubabukeli kwihlabathi liphela.
