Ikhebula le-USB Active Optical (AOC) ubuchwepheshe obuhlanganisa izinzuzo zezintambo ze-optical kanye nezixhumi zikagesi zendabuko. Lisebenzisa ama-chip okuguqula i-photoelectric ahlanganiswe kuzo zombili izinhlangothi zekhebula ukuze lihlanganise izintambo ze-optical kanye nezintambo ngokwemvelo. Lo mklamo uvumela i-AOC ukuthi inikeze izinzuzo eziningi kunezintambo zethusi zendabuko, ikakhulukazi ekudlulisweni kwedatha okude, okusheshayo. Lesi sihloko sizohlaziya kakhulu isimiso sokusebenza sekhebula le-optical le-USB elisebenzayo.
Izinzuzo zekhebula le-USB elisebenzayo le-fiber optic
Izinzuzo ze-USB esebenzayoizintambo ze-fiber opticzisobala kakhulu, kufaka phakathi amabanga amade okudlulisa. Uma kuqhathaniswa nezintambo zethusi ze-USB zendabuko, i-USB AOC ingasekela ibanga lokudlulisa eliphezulu elingaphezu kwamamitha ayi-100, okwenza zifaneleke kakhulu ezinhlelweni zokusebenza ezidinga ukuwela izikhala ezinkulu ezibonakalayo, njengamakhamera okuphepha, ukuzenzekela kwezimboni, kanye nokudluliswa kwedatha emishinini yezokwelapha. Kunezivinini zokudlulisa eziphakeme nakakhulu, ngezintambo ze-USB 3.0 AOC ezikwazi ukufika ku-5 Gbps, kuyilapho amazinga amasha njenge-USB4 engasekela izivinini zokudlulisa ezifika ku-40Gbps noma ngaphezulu. Lokhu kusho ukuthi abasebenzisi bangajabulela izivinini zokudlulisa idatha ezisheshayo ngenkathi begcina ukuhambisana nezixhumi ze-USB ezikhona.
Ngaphezu kwalokho, inekhono elingcono lokulwa nokuphazamiseka. Ngenxa yokusebenzisa ubuchwepheshe be-fiber optic, i-USB AOC inokuhambisana okuhle kakhulu kwe-electromagnetic (EMC), okungamelana ngempumelelo nokuphazamiseka kwe-electromagnetic (EMI). Lokhu kubaluleke kakhulu ekusetshenzisweni ezindaweni ezinamandla ze-electromagnetic, njengokuxhumeka kwezinsimbi ezinembile ezibhedlela noma ezindaweni zokusebenzela zasefektri. Ilula futhi incane, uma iqhathaniswa nezintambo zethusi zendabuko ezinobude obufanayo, i-USB AOC ilula futhi iguquguquka, yehlisa isisindo sayo kanye nomthamo wayo ngaphezu kuka-70%. Lesi sici sizuzisa kakhulu kumadivayisi eselula noma izimo zokufakwa ezinezidingo zesikhala eziqinile. Ezimweni eziningi, i-USB AOC ingaxhunywa futhi idlale ngqo ngaphandle kwesidingo sokufaka noma iyiphi isofthiwe yomshayeli ekhethekile.
Isimiso sokusebenza
Isimiso sokusebenza se-USB AOC sisekelwe ezingxenyeni ezine eziyinhloko.
1. Ukufakwa kwesignali kagesi: Uma idivayisi ithumela idatha nge-interface ye-USB, isignali kagesi ekhiqizwayo iqala ifike ekugcineni kwe-AOC. Isignali kagesi lapha iyafana naleyo esetshenziswa ekudlulisweni kwekhebula lethusi lendabuko, okuqinisekisa ukuhambisana nezindinganiso ze-USB ezikhona.
2. Ukuguqulwa kukagesi kube okubonakalayo: Ama-laser akhipha ubuso obuvundlile obuyi-vertical cavity eyodwa noma ngaphezulu afakwe ekugcineni kwekhebula le-AOC, elinomthwalo wokuguqula amasignali kagesi atholiwe abe amasignali okubonakalayo.
3. Ukudluliswa kwe-fiber optic: Uma izimpawu zikagesi seziguqulwe zaba izimpawu ezibonakalayo, lezi ziphazamiso ezibonakalayo zizodluliswa amabanga amade ngekhebula le-fiber optic. Ngenxa yezici zokulahlekelwa eziphansi kakhulu zezintambo ezibonakalayo, zingagcina amazinga aphezulu okudluliswa kwedatha ngisho namabanga amade futhi cishe azithinteki ukuphazamiseka kwe-electromagnetic yangaphandle.
4. Ukuguqulwa kokukhanya kuya kugesi: Lapho ulwazi lokuthwala i-pulse yokukhanya lufika kolunye uhlangothi lwekhebula le-AOC, luzohlangana ne-photodetector. Le divayisi iyakwazi ukuthwebula izimpawu ezibonakalayo bese iziguqula zibe yisimo sazo sokuqala sesignali kagesi. Ngemva kwalokho, ngemva kokukhulisa kanye nezinye izinyathelo zokucubungula ezidingekayo, isignali kagesi etholiwe izodluliselwa kudivayisi eqondiwe, kuqedwe yonke inqubo yokuxhumana.
