Intambo ye-USB Active Optical (AOC) yiteknoloji edibanisa iingenelo zeefayibha ze-optical kunye nezihlanganisi zombane zemveli. Isebenzisa iitships zokuguqula i-photoelectric ezidityaniswe kuzo zombini iziphelo zentambo ukudibanisa iifayibha ze-optical kunye neentambo ngokwendalo. Olu yilo luvumela i-AOC ukuba ibonelele ngeenzuzo ezahlukeneyo kuneentambo ze-copper zemveli, ingakumbi kwiindlela ezinde zokuhambisa idatha ngesantya esiphezulu. Eli nqaku liza kuhlalutya ikakhulu umgaqo wokusebenza kwentambo ye-optical esebenzayo ye-USB.
Iingenelo zentambo ye-fiber optic esebenzayo ye-USB
Iingenelo ze-USB esebenzayoiintambo ze-fiber opticzicacile kakhulu, kuquka umgama omde wokudlulisa. Xa kuthelekiswa neentambo ze-USB zekopolo zemveli, i-USB AOC inokuxhasa umgama ophezulu wokudlulisa ongaphezulu kweemitha ezili-100, nto leyo eyenza ukuba zifaneleke kakhulu kwizicelo ezifuna ukunqumla iindawo ezinkulu ezibonakalayo, ezifana neekhamera zokhuseleko, ukuzenzekela kwemizi-mveliso, kunye nokudluliselwa kwedatha kwizixhobo zonyango. Kukho isantya sokudlulisa esiphezulu ngakumbi, kunye neentambo ze-USB 3.0 AOC ezinokufikelela kwi-5 Gbps, ngelixa imigangatho emitsha efana ne-USB4 inokuxhasa isantya sokudlulisa esifikelela kwi-40Gbps okanye ngaphezulu. Oku kuthetha ukuba abasebenzisi banokonwabela isantya sokudlulisa idatha esikhawulezayo ngelixa begcina ukuhambelana ne-interfaces ze-USB ezikhoyo.
Ukongeza, ikwanayo nokukwazi okungcono kokulwa nokuphazamiseka. Ngenxa yokusetyenziswa kwetekhnoloji ye-fiber optic, i-USB AOC inokuhambelana okuhle kakhulu kwe-electromagnetic (EMC), enokuxhathisa ngempumelelo ukuphazamiseka kwe-electromagnetic (EMI). Oku kubaluleke kakhulu kwizicelo kwiindawo ezinamandla ze-electromagnetic, ezifana noqhagamshelo lwezixhobo ezichanekileyo kwizibhedlele okanye kwiindawo zokusebenzela zasefektri. Ilula kwaye incinci, xa ithelekiswa neentambo zendabuko zobhedu ezinobude obufanayo, i-USB AOC ilula kwaye iguquguquka, inciphisa ubunzima bayo kunye nomthamo wayo ngaphezulu kwe-70%. Olu phawu luluncedo ngakumbi kwizixhobo eziphathwayo okanye kwiimeko zokufakela ezineemfuno ezingqongqo zendawo. Kwiimeko ezininzi, i-USB AOC inokuxhunywa kwaye idlalwe ngokuthe ngqo ngaphandle kwesidingo sokufaka nayiphi na isoftware yomqhubi ekhethekileyo.
Umgaqo wokusebenza
Umgaqo wokusebenza we-USB AOC usekelwe kwizinto ezine eziphambili.
1. Ukufakwa kwesignali yombane: Xa isixhobo sithumela idatha nge-USB interface, isignali yombane evelisiweyo kuqala ifikelela kwelinye icala le-AOC. Isignali yombane apha iyafana naleyo isetyenziswa kwi-transmission yendabuko yekhebula lethusi, ukuqinisekisa ukuhambelana nemigangatho ye-USB ekhoyo.
2. Ukuguqulwa kombane ukuya kwi-optical: I-laser enye okanye ezingaphezulu ezikhupha umphezulu ongaphakathi zifakwe kwelinye icala lentambo ye-AOC, ezinoxanduva lokuguqula imiqondiso yombane efunyenweyo ibe yimiqondiso ye-optical.
3. Ukudluliselwa kwe-fiber optic: Nje ukuba imiqondiso yombane iguqulwe yaba yimiqondiso ye-optical, ezi pulses ze-optical ziya kudluliselwa kumgama omde ngentambo ye-fiber optic. Ngenxa yeempawu eziphantsi kakhulu zokulahleka kwe-fiber optical, zinokugcina amazinga aphezulu okudluliselwa kwedatha nokuba kumgama omde kwaye azichaphazeleki phantse kukuphazamiseka kwe-electromagnetic yangaphandle.
4. Ukuguqulwa kokukhanya ukuya kumbane: Xa ulwazi oluthwala i-pulse yokukhanya lufikelela kwelinye icala lentambo ye-AOC, luya kudibana ne-photodetector. Esi sixhobo sinako ukubamba imiqondiso ye-optical size siyiguqulele kwimo yaso yokuqala yesignali yombane. Emva koko, emva kokwandiswa kunye namanye amanyathelo afunekayo okucubungula, isignali yombane efunyenweyo iya kudluliselwa kwisixhobo ekujoliswe kuso, igqibezele yonke inkqubo yonxibelelwano.
