Mfundo yogwirira ntchito ya chingwe chowunikira cha USB

Chingwe cha USB Active Optical (AOC) ndi ukadaulo womwe umaphatikiza ubwino wa ulusi wa kuwala ndi zolumikizira zamagetsi zachikhalidwe. Chimagwiritsa ntchito ma chip osinthira kuwala omwe amaphatikizidwa kumapeto onse a chingwe kuti aphatikize ulusi wa kuwala ndi zingwe mwachilengedwe. Kapangidwe kameneka kamalola AOC kupereka zabwino zosiyanasiyana kuposa zingwe zamkuwa zachikhalidwe, makamaka pakutumiza deta patali komanso mwachangu. Nkhaniyi isanthula makamaka mfundo yogwirira ntchito ya chingwe cha USB active optical.

Ubwino wa chingwe cha USB chogwira ntchito cha fiber optic

Ubwino wa USB yogwira ntchitozingwe za fiber opticndi zoonekeratu, kuphatikizapo mtunda wautali wotumizira mauthenga. Poyerekeza ndi zingwe zamkuwa za USB, USB AOC imatha kuthandizira mtunda wapamwamba kwambiri wotumizira mauthenga wopitilira mamita 100, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pa mapulogalamu omwe amafunika kudutsa malo akuluakulu, monga makamera achitetezo, makina odziyimira pawokha a mafakitale, ndi kutumiza deta muzipangizo zachipatala. Palinso liwiro lalikulu kwambiri lotumizira mauthenga, ndi zingwe za USB 3.0 AOC zomwe zimatha kufika pa 5 Gbps, pomwe miyezo yatsopano monga USB4 imatha kuthandizira kuthamanga kwa mauthenga mpaka 40Gbps kapena kupitirira apo. Izi zikutanthauza kuti ogwiritsa ntchito amatha kusangalala ndi liwiro lotumizira deta mwachangu pomwe akupitilizabe kugwirizana ndi ma interface a USB omwe alipo.

Kuphatikiza apo, ilinso ndi mphamvu yabwino yoletsa kusokonezedwa. Chifukwa chogwiritsa ntchito ukadaulo wa fiber optic, USB AOC ili ndi electromagnetic compatibility yabwino kwambiri (EMC), yomwe imatha kukana kusokonezedwa kwa electromagnetic (EMI). Izi ndizofunikira kwambiri pakugwiritsa ntchito m'malo amphamvu a electromagnetic, monga kulumikizana kolondola kwa zida m'zipatala kapena m'mafakitale. Yopepuka komanso yaying'ono, poyerekeza ndi zingwe zamkuwa zachikhalidwe zautali womwewo, USB AOC ndi yopepuka komanso yosinthasintha, imachepetsa kulemera kwake ndi voliyumu yake ndi kupitirira 70%. Mbali imeneyi ndi yothandiza makamaka pazida zam'manja kapena zochitika zoyika zomwe zimakhala ndi malo ofunikira kwambiri. Nthawi zambiri, USB AOC imatha kulumikizidwa ndikuseweredwa mwachindunji popanda kufunikira kuyika pulogalamu iliyonse yapadera yoyendetsera.

Mfundo yogwirira ntchito

Mfundo yogwirira ntchito ya USB AOC imachokera ku zigawo zinayi zazikulu.

1. Kulowetsa chizindikiro chamagetsi: Chipangizo chikatumiza deta kudzera mu USB interface, chizindikiro chamagetsi chomwe chimapangidwa chimafika koyamba kumapeto kwa AOC. Zizindikiro zamagetsi pano ndizofanana ndi zomwe zimagwiritsidwa ntchito potumiza chingwe chamkuwa, zomwe zimatsimikizira kuti zikugwirizana ndi miyezo ya USB yomwe ilipo.

2. Kusintha kwa magetsi kukhala kuwala: Ma laser amodzi kapena angapo ozungulira omwe amatulutsa pamwamba pa cavity amaikidwa kumapeto kwa chingwe cha AOC, chomwe chimayang'anira kusintha ma siginolo amagetsi olandiridwa kukhala ma siginolo a kuwala.

3. Kutumiza kwa fiber optic: Zizindikiro zamagetsi zikasinthidwa kukhala zizindikiro zowunikira, ma pulse awa amatumizidwa mtunda wautali motsatira chingwe cha fiber optic. Chifukwa cha kuchepa kwa kutayika kwa ulusi wowunikira, amatha kusunga kuchuluka kwa kutumiza deta ngakhale mtunda wautali ndipo sakhudzidwa ndi kusokonezedwa kwa ma elekitiromagineti akunja.

4. Kusintha kwa kuwala kupita ku magetsi: Pamene chidziwitso chonyamula kuwala chikufika kumapeto ena a chingwe cha AOC, chimakumana ndi chowunikira kuwala. Chipangizochi chimatha kujambula zizindikiro za kuwala ndikuzisintha kukhala mawonekedwe ake oyamba a chizindikiro chamagetsi. Pambuyo pake, pambuyo pokulitsa ndi njira zina zofunika zokonzera, chizindikiro chamagetsi chobwezedwacho chidzatumizidwa ku chipangizo chomwe chikufunidwa, ndikumaliza njira yonse yolumikizirana.
