Yenza Ntoni Intambo Yokukhanya?

Izinto eziphambili zokuThatha
● Intambo yokubona ithumela i-audio njenge-pulses yokukhanya, ikunika isandi esicacileyo ngaphandle kwengxolo yombane.
● Iphatha i-stereo PCM Dolby Digital (ukuya kwi-5.1), kunye neefomathi ze-DTS, kodwa kungekhona i-codecs ephezulu-bit-rate engalahlekanga njenge-Dolby TrueHD okanye i-DTS-HD Master Audio.
● Uya kufumana amazibuko okukhanya kwiiTV, iibar zesandi, kunye nabamkeli bethiyetha yasekhaya xa ufuna unxibelelwano olulula, oluthembekileyo ngaphandle kwe-ground-loop hum.
● Ukuqhuba umgama omde okanye uthungelwano lwedatha, iinguqulelo zeglasi-fiber zithwala imiqondiso yeekhilomitha ngelahleko ephantsi kakhulu.
● Ukukhetha intambo efanelekileyo kuthetha ukuhambelana nodidi lwefayibha (iplastiki vs. iglasi), ubude, kunye nomgangatho wesihlanganisi kulungiselelo lwakho.

 
1. Intshayelelo
Unokubona izibuko elithi “Optical” okanye “Digital Audio Out” ngasemva kweTV yakho, ibha yesandi, okanye iAV kwaye ucinge ukuba lelinye nje igalelo. Kodwa ukwazi yintoni eyenziwa yintambo yokukhanya inokukusindisa ekuphumeni komsindo ocaphukisayo, i-ground-loop hum, kunye neentloko ezihambelanayo-ingakumbi xa ubhangqa iziboniso zale mihla kunye negiya ye-audio yelifa okanye ukuhambisa iaudio engenangxolo kwiiseti zethiyetha yasekhaya entsonkothileyo.
Intambo yokukhanya, edla ngokubizwa ngokuba yi-TOSLINK (i-Toshiba Link) okanye i-digital optical cable, ihambisa i-audio njenge-pulses yokukhanya kwe-infrared kuneempawu zombane. Olu tshintsho lulula lususa phantse lonke uphazamiseko, lugcina amava akho okumamela enyulu, kwaye ludlulela ngaphaya komsindo womgangatho wabathengi ukuya kunxibelelwano lwedatha, ukuhanjiswa kwebroadband "yemayile yokugqibela", kunye nezinzwa ezichanekileyo zemizi-mveliso.
Eli nqaku liphonononga:
● Yintoni intambo ye-optical kwaye ivela phi
● Isebenza njani ngokwenene ukuthwala iaudio
● Iinzuzo eziphambili ngaphezu kwezinye iintlobo zeentambo

● Indlela yokukhetha, ukufaka, kunye nokucombulula iingxaki zeentambo zamehlo
● Iindlela ezivelayo eziza kubumba ikamva le-fiber-optic links
Ekugqibeleni, uya kuqonda yintoni eyenziwa yintambo yokukhanya, nini ukusebenzisa enye, kunye nendlela yokukhetha intambo efanelekileyo kuso nasiphi na isicelo.

 
2. Yintoni i-Optical Cord?
Intambo yamehlo-ekwabizwa ngokuba yi-a intambo yedijithali okanye i-TOSLINK-yintambo ephethe idatha yedijithali ye-audio ngokusebenzisa i-pulses elula ngefayibha ebhityileyo. Ngokungafaniyo neentambo ezisekwe kubhedu, isebenzisa nokuba yiglasi okanye ifayibha yeplastiki ukuhambisa ulwazi, iyenza i-100% ikhuseleke kwi-electromagnetic interference (EMI) kunye ne-ground-loop hum eqhelekileyo ngoqhagamshelo lombane.
Ekuqaleni yaziswa nguToshiba kwi-1983 ukudibanisa abadlali be-CD kubamkeli, umgangatho we-TOSLINK ngokukhawuleza waba yindlela yokudibanisa amacandelo omsindo wabathengi. Ngokuhamba kwexesha, ifom yefom yavela kwi-Mini-TOSLINK (i-3.5 mm iplagi yee-laptops kunye nezixhobo eziphathekayo) kunye nexabiso eliphantsi leplastiki ye-fiber optical fiber (POF) eyahlukeneyo yezicelo ezinohlahlo-lwabiwo-mali kunye nokuhamba okufutshane.
