Kwihlabathi le-cable television (CATV), ukuqinisekisa ukusebenza kakuhle kunye nomgangatho wesignali kubalulekile ekuboneleleni abathengi ngamava okubukela angenamthungo. Izandiso zemigca zeCATV zidlala indima ebalulekileyo ekwandiseni ukusebenza kwenkqubo ye-cable television ngokwandisa uluhlu lwesignali kunye nokuphucula umgangatho wesignali iyonke. Kweli nqaku, siza kuhlola iingenelo zezandiso zemigca zeCATV kunye nendlela ezinokunceda ngayo ukwandisa ukusebenza kweCATV.
Izandiso zomgca weCATVzizinto ezibalulekileyo kwiinkqubo zeTV yekhebula, ingakumbi xa imiqondiso kufuneka idluliselwe kumgama omde okanye kwiindawo ezinelahleko ephezulu yesignali. Ezi zixhobo zisebenza ngokwandisa isignali kwaye zihlawulele nayiphi na ilahleko enokwenzeka ngelixa isignali idluliselwa ngenethiwekhi enentambo. Ngokwandisa amandla esignali, izandisi zemigca ziqinisekisa ukuba isignali ifikelela kwindawo ekujoliswe kuyo ngokunciphisa okuncinci, okubonelela ngomfanekiso ongcono kunye nomgangatho wesandi kumsebenzisi wokugqibela.
Enye yezona nzuzo ziphambili zokusebenzisa i-CATV line extender kukukwazi ukwandisa ukugquma kwesignali yeTV yakho yekhebula. Oku kuluncedo ngakumbi kwiinethiwekhi ezinkulu ezineentambo ezifuna ukusasaza imiqondiso kwindawo ebanzi yejografi. Ngokubeka i-line extenders kwiindawo ezicwangcisiweyo kwinethiwekhi, abaqhubi bekhebula banokwandisa ngempumelelo ukugquma kwesignali zabo, beqinisekisa ukuba nabasebenzisi abakude kakhulu bafumana isignali eqinileyo necacileyo.
Ukongeza, izandiso zomgca we-CATV zidlala indima ebalulekileyo ekulweni nokulahleka kwesiginali kunye nokuphambuka okubangelwa zizinto ezinje ngokuncipha kwentambo, ukungalingani kwe-impedance, kunye nokuphazamiseka kwendalo. Ezi ngxaki zinokunciphisa kakhulu umgangatho wesiginali, nto leyo ebangela umgangatho ophantsi womfanekiso kunye nokulahleka kwesiginali. Izandiso zomgca zinceda ekunciphiseni ezi ngxaki ngokwandisa isiginali kunye nokuhlawula nayiphi na ilahleko, nto leyo ebangela ukudluliselwa kwesiginali okuqinileyo nokuthembekileyo.
Enye inzuzo yokusebenzisa ii-CATV line extenders kukukwazi kwazo ukuxhasa ukuhanjiswa komxholo we-high definition (HD) kunye ne-ultra high definition (UHD). Njengoko imfuno yomxholo wevidiyo osemgangathweni iqhubeka ikhula, abaqhubi beentambo baphantsi koxinzelelo lokubonelela ngomgangatho ophezulu wemifanekiso kubabhalisi babo. Ii-line extenders zidlala indima ebalulekileyo ekuqinisekiseni ukuba imiqondiso ye-HD kunye ne-UHD idluliselwa ngokuthembeka okuphezulu, okuvumela abasebenzisi ukuba bonwabele amava okubukela anomdla ngokwenene.
Ukongeza, izandiso zemigca zinegalelo ekuthembekeni nasekuzinzeni kwenkqubo yakho yeTV yekhebula. Ngokugcina ukuthembeka kwesignali kunye nokuhlawula ukulahleka kwesignali, izandiso zemigca zinceda ekunciphiseni ukuphazamiseka kwenkonzo kwaye ziqinisekise ukusebenza rhoqo kuyo yonke inethiwekhi. Oku kubaluleke kakhulu kwiindawo ezisengozini yokuwohloka kwesignali, njengeendawo ezikude okanye zasemaphandleni, apho ukusebenzisa izandiso zemigca kunokuphucula kakhulu ukuthembeka kwenkonzo yakho yeTV yekhebula.
Konke kwinto enye,Izandiso zomgca weCATVzizixhobo ezibalulekileyo zokwandisa ukusebenza kwenkqubo yakho yeTV yekhebula. Izandisi zemigca zidlala indima ebalulekileyo ekuqinisekiseni ukuba ababhalisile bafumana amava okubukela aphezulu ngokwandisa ukugubungela isignali, ukuhlawula ilahleko yesignali, kunye nokuxhasa ukuhanjiswa komxholo osemgangathweni ophezulu. Njengoko imfuno yomxholo wevidiyo osemgangathweni ophezulu iqhubeka ikhula, ukubaluleka kwezandisi zemigca ekugcineni ukusebenza kweCATV okuphezulu akunakugxininiswa kakhulu. Abaqhubi bekhebula abafuna ukuphucula umgangatho kunye nokuthembeka kwenkonzo yabo yekhebula kufuneka baqwalasele ukusasazwa kwezandisi zemigca njengotyalo-mali olubalulekileyo ekuphuculeni ukusebenza kwekhebula.
