Nakuba inhloso eyisisekelo yakho kokubili iwukudlulisa idatha ngokukhanya, izakhiwo, izinhlelo zokusebenza, kanye ne-pe...Funda kabanzi -
Umgomo wokusebenza wekhebula le-USB elisebenzayo
Ikhebula le-USB Active Optical (AOC) ubuchwepheshe obuhlanganisa izinzuzo zemicu yokubona nezixhumi zikagesi zendabuko. Isebenzisa ama-photoelectric conversion chips ahlanganiswe kuzo zombili iziphetho zekhebula ukuze kuhlanganiswe ngokwemvelo imicu yokubona nezintambo. Lo mklamo uvumela i-AOC ukuthi inikeze uhla lwezinzuzo ngaphezu kwezintambo zethusi zendabuko, ikakhulukazi kumzila wedatha ode, onesivinini esikhulu...Funda kabanzi -
Izici nokusetshenziswa kwezixhumi zohlobo lwe-UPC ze-fiber optic
Uhlobo lwe-UPC isixhumi se-fiber optic siwuhlobo lwesixhumi esivamile emkhakheni wezokuxhumana we-fiber optic, lesi sihloko sizohlaziya izici zayo nokusetshenziswa kwayo. Izici zesixhumi se-fiber optic yohlobo lwe-UPC 1. Umumo wobuso bokuphela kobuso bephinikhodi yesixhumi se-UPC ulungiselelwe ukwenza ubuso bawo bushelelezi, obumise okwedome. Lo mklamo uvumela i-fiber optic end face ukuthi ifinyelele ukuxhumana okusondelene ...Funda kabanzi -
Intambo ye-Fiber optic: ukuhlaziywa okujulile kwezinzuzo kanye nokubi
Kubuchwepheshe besimanje bezokuxhumana, izintambo ze-fiber optic zidlala indima ebalulekile. Lesi sikhungo, esidlulisela idatha ngamasignali okubona, sithatha indawo engenakushintshwa emkhakheni wokudluliselwa kwedatha ngesivinini esikhulu ngenxa yezimpawu zayo eziyingqayizivele. Izinzuzo Zezintambo Ze-Fiber Optic Ukudluliswa kwesivinini esiphezulu: Izintambo ze-Fiber optic zinganikeza amanani aphezulu kakhulu okudlulisa idatha, i-theoretic...Funda kabanzi -
Isingeniso ku-PAM4 Technology
Ngaphambi kokuqonda ubuchwepheshe be-PAM4, buyini ubuchwepheshe be-modulation? Ubuchwepheshe bokuguquguquka buyindlela yokuguqula amasignali e-baseband (amasignali kagesi angahluziwe) abe amasignali okudlulisa. Ukuze uqinisekise ukusebenza kahle kokuxhumana futhi unqobe izinkinga ekudluliselweni kwesignali yebanga elide, kuyadingeka ukudlulisa i-spectrum yesiginali esiteshini esiphezulu-frequency ngokusebenzisa i-modulation ye ...Funda kabanzi -
Imishini eminingi esebenzayo yokuxhumana kwe-fiber optic: ukumiswa nokuphathwa kwama-transceivers e-fiber optic
