I-USB Active Optical Cable (AOC) iteknoloji edibanisa iingenelo zeentsinga zamehlo kunye nezihlanganisi zombane zemveli. Isebenzisa iitshiphusi zokuguqulwa kweefoto zombane ezidityaniswe kuzo zombini iziphelo zentambo ukudibanisa ngokwendalo iifiber ezibonakalayo kunye neentambo. Olu luyilo luvumela i-AOC ukuba ibonelele ngoluhlu lweenzuzo kwiintambo zobhedu zendabuko, ngokukodwa kumgama omde, ukuhanjiswa kwedatha ngesantya esiphezulu. Eli nqaku liza kuhlalutya umgaqo osebenzayo we-USB esebenzayo intambo yokukhanya.
Izinto ezilungileyo ze-USB esebenzayo intambo yefiber optic
Uncedo lwe-USB esebenzayoiintambo zefiber opticzicace kakhulu, kubandakanywa imigama emide yothumelo. Xa kuthelekiswa neentambo zobhedu ze-USB zemveli, i-USB AOC inokuxhasa umgama ophezulu wothumelo ongaphezu kweemitha ezili-100, ibenze bafaneleke kakhulu kwizicelo ezifuna ukuwela izithuba ezinkulu zomzimba, ezinje ngeekhamera zokhuseleko, i-automation ye-industrial, kunye nokuhanjiswa kwedatha kwizixhobo zonyango. Kukho isantya esiphezulu sothumelo, kunye neentambo ze-USB 3.0 AOC ezikwazi ukuya kuthi ga kwi-5 Gbps, ngelixa imigangatho emitsha efana ne-USB4 inokuxhasa isantya sothumelo ukuya kuthi ga kwi-40Gbps okanye nangaphezulu. Oku kuthetha ukuba abasebenzisi banokonwabela isantya sokudlulisa idatha ngokukhawuleza ngelixa begcina ukuhambelana nojongano olukhoyo lwe-USB.
Ukongeza, ikwanesakhono esingcono sokuchasana nokuphazamiseka. Ngenxa yokusetyenziswa kweteknoloji yefiber optic, i-USB AOC inokufaneleka kwe-electromagnetic egqwesileyo (EMC), enokumelana ngempumelelo nokuphazamiseka kombane (EMI). Oku kubaluleke kakhulu kwizicelo ezikwiindawo ezomeleleyo ze-electromagnetic, ezinje ngoqhagamshelo lwesixhobo esichanekileyo kwizibhedlele okanye kwiindibano zocweyo zasefektri. I-Lightweight kunye ne-compact, xa kuthelekiswa neentambo zobhedu zendabuko zobude obufanayo, i-USB AOC ilula kakhulu kwaye iguquguqukayo, iyanciphisa ubunzima bayo kunye nomthamo ngaphezu kwe-70%. Olu phawu luluncedo ngakumbi kwizixhobo eziphathwayo okanye iimeko zofakelo ezineemfuno ezingqongqo zendawo. Kwiimeko ezininzi, i-USB AOC inokuplagi kwaye idlale ngokuthe ngqo ngaphandle kwesidingo sokufakela nayiphi na isoftware yomqhubi okhethekileyo.
Umgaqo wokusebenza
Umgaqo osebenzayo we-USB AOC usekelwe kwizinto ezine eziphambili.
1. Ukufakwa kwesignali yombane: Xa isixhobo sithumela idatha nge-USB interface, isibonakaliso sombane esiveliswayo sifika kuqala ekupheleni kwe-AOC. Iimpawu zombane apha ziyafana nezo zisetyenziselwa ukuhanjiswa kwentambo yobhedu yendabuko, iqinisekisa ukuhambelana nemigangatho ekhoyo ye-USB.
2. Umbane ukuya kuguquko lwe-optical: I-laser enye okanye ngaphezulu ye-vertical cavity surface emitting ifakwe kwelinye icala lekhebula le-AOC, elijongene nokuguqula iimpawu zombane ezifunyenweyo kwiimpawu ze-optical.
3. Ukuhanjiswa kweFiber optic: Emva kokuba imiqondiso yombane iguqulelwe kwimiqondiso ye-optical, ezi pulses zamehlo ziya kuhanjiswa kumgama omde ecaleni kwentambo yefiber optic. Ngenxa yelahleko ephantsi kakhulu yeempawu ze-optical fibers, zinokugcina amazinga aphezulu othumelo lwedatha nakwimigama emide kwaye phantse azichatshazelwa luphazamiseko lwangaphandle lwe-electromagnetic.
4. Ukukhanya kukuguqulwa kombane: Xa i-pulse yokukhanya ephethe ulwazi ifikelela kwelinye icala lentambo ye-AOC, iya kuhlangana ne-photodetector. Esi sixhobo siyakwazi ukubamba imiqondiso ye-optical kwaye siyiguqulele kwifom yesignali yombane yokuqala. Emva koko, emva kokukhulisa kunye namanye amanyathelo okusebenza ayimfuneko, umqondiso wombane ofunyenweyo uya kuhanjiswa kwisixhobo esijoliswe kuyo, ukugqiba yonke inkqubo yonxibelelwano.
