Kanema wa kanema wawayilesi wakhala gawo la moyo wathu kwazaka zambiri, akutipatsa zosangalatsa komanso chidziwitso m'nyumba zathu. Komabe, ndi kupita patsogolo kofulumira kwaukadaulo, TV yachikhalidwe yachikhalidwe ikusokonezedwa, ndipo nyengo yatsopano ikubwera. Tsogolo la chingwe cha TV lagona pakuphatikizidwa kwaukadaulo wa CATV ONU (Cable TV Optical Network Unit).
CATV ONUs, yomwe imadziwikanso kuti fiber-to-the-home (FTTH) zipangizo, zikugwira ntchito yofunika kwambiri pakusintha njira yoperekera chingwe TV. Tekinolojeyi imabweretsa intaneti yothamanga kwambiri, wailesi yakanema ya digito ndi mautumiki apamawu molunjika kunyumba ya ogwiritsa ntchito kudzera pa zingwe za fiber optic. Idalowa m'malo mwa chingwe chachikhalidwe cha coaxial, idapereka zabwino zambiri, ndikutsegulira njira yosinthira makampani a TV.
Mmodzi mwa ubwino waukulu waCATV ONUteknoloji ndi bandwidth yodabwitsa yomwe imapereka. Zingwe za fiber optic zimakhala ndi mphamvu yodabwitsa ndipo zimatha kusamutsa deta yambiri pa liwiro lodabwitsa. Mwa kuphatikiza ma CATV ONU, opereka ma TV atha kupereka njira za UHD, ntchito zotsatsira zomwe mukufuna, komanso zinthu zomwe simunaganizirepo kale. Kupita patsogolo kwa bandwidth kumapangitsa kuti ogula aziwonera mopanda msoko komanso zowoneka bwino.
Kuphatikiza apo, ukadaulo wa CATV ONU sikuti umangowonjezera mtundu ndi kuchuluka kwa mayendedwe omwe alipo, komanso umathandizira makonda ndi zosankha zamunthu. Kupyolera mu kuphatikizika kwa kulumikizidwa kwa intaneti, ogula amatha kugwiritsa ntchito mapulogalamu osiyanasiyana, kuphatikizapo mavidiyo omwe akufunafuna mavidiyo, maulendo osindikizira ndi zinthu zomwe zimagwiritsidwa ntchito. Izi zimathandiza owerenga kusankha momasuka zimene ndi pamene akufuna kuonera, kwathunthu kusintha chikhalidwe chingwe TV chitsanzo.
Ubwino winanso wofunikira waukadaulo wa CATV ONU ndi kuthekera kwake pakupulumutsa mtengo. Zingwe za fiber optic ndizodalirika kwambiri ndipo zimafuna kusamalidwa pang'ono kuposa zingwe zachikhalidwe za coaxial. Kuchuluka kwa zomangamanga kumachepetsa kufunika kokonzanso pafupipafupi ndikusinthanso, kuchepetsa ndalama kwa opereka chingwe. Chifukwa chake, ndalama zopulumutsa izi zitha kuperekedwa ku phindu la ogula, zomwe zimapangitsa kuti pakhale ma phukusi otsika mtengo a TV.
Kuphatikiza apo, ukadaulo wa CATV ONU umapereka mwayi kwa othandizira ma TV kuti apereke ntchito zambiri. Kupyolera mu kuphatikizika kwa mautumiki a mawu ndi intaneti yothamanga kwambiri, ogula amatha kukwaniritsa zosowa zawo zonse zoyankhulana ndi zosangalatsa kuchokera kwa wothandizira mmodzi. Kuphatikizika kwa mautumikiwa kumapangitsa kuti ogula asamavutike komanso kuchotseratu zovuta zowongolera zolembetsa zingapo.
Kuphatikiza apo, scalability ndi kusinthasintha kwaukadaulo wa CATV ONU kumapangitsa kukhala umboni wamtsogolo. Pomwe ukadaulo ukupitilira kupita patsogolo, kuphatikiza kwazinthu zatsopano ndi ntchito kumakhala kosasunthika ndi ma fiber optic network. Othandizira ma TV a Cable amatha kusintha mosavuta kusintha zosowa ndi zokonda za ogula, kuonetsetsa kuti akukhalabe opikisana komanso ali patsogolo pa malonda.
Mwachidule, tsogolo la chingwe TV lagona mu kuphatikiza kwaCATV ONUluso. Yankho latsopanoli limasintha mtundu wa TV wachikhalidwe, kupereka bandwidth yowonjezereka, zosankha makonda komanso kupulumutsa mtengo. Potengera ukadaulo uwu, opereka ma TV amatha kukwaniritsa zofuna za ogula pazinthu zapamwamba kwambiri, zokumana nazo zamunthu payekha komanso ntchito zambiri. Zaka zaukadaulo za CATV ONU zafika, zikuyambitsa nthawi yatsopano ya kanema wawayilesi, kubweretsa tsogolo lowala komanso losangalatsa kwa owonera padziko lonse lapansi.
