Ngenkathi inhloso eyisisekelo yazo zombili iwukudlulisa idatha ngokukhanya, izakhiwo zazo, izinhlelo zokusebenza, kanye...Funda kabanzi -
Isimiso sokusebenza sekhebula le-USB elisebenzayo
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...Funda kabanzi -
Izici kanye nokusetshenziswa kwezixhumi ze-fiber optic zohlobo lwe-UPC
Isixhumi se-fiber optic sohlobo lwe-UPC siwuhlobo lwesixhumi esivamile emkhakheni wokuxhumana kwe-fiber optic, lesi sihloko sizohlaziya izici zaso kanye nokusetshenziswa kwaso. Izici zesixhumi se-fiber optic sohlobo lwe-UPC 1. Ukuma kobuso bokugcina Ubuso bokuphela kwephini yesixhumi se-UPC bulungiselelwe ukwenza ubuso baso bube bushelelezi, bube njengedome. Lo mklamo uvumela ubuso bokuphela kwe-fiber optic ukuthi bufinyelele ukuxhumana okuseduze...Funda kabanzi -
Ikhebula le-Fiber optic: ukuhlaziywa okujulile kwezinzuzo kanye nokungalungi
Ebuchwephesheni bezokuxhumana besimanje, izintambo ze-fiber optic zidlala indima ebalulekile. Le ndlela, edlulisa idatha ngezibonakaliso ze-optical, ithatha indawo engenakuphikwa emkhakheni wokudluliselwa kwedatha ngesivinini esikhulu ngenxa yezici zayo zomzimba ezihlukile. Izinzuzo Zezintambo ze-Fiber Optic Ukudluliselwa kwesivinini esikhulu: Izintambo ze-fiber optic zinganikeza amazinga aphezulu kakhulu okudluliselwa kwedatha, i-theoretic...Funda kabanzi -
Isingeniso kubuchwepheshe be-PAM4
Ngaphambi kokuqonda ubuchwepheshe be-PAM4, buyini ubuchwepheshe bokushintshashintsha? Ubuchwepheshe bokushintshashintsha buyindlela yokuguqula izimpawu ze-baseband (izimpawu zikagesi ezingavuthiwe) zibe izimpawu zokudlulisa. Ukuze kuqinisekiswe ukusebenza kahle kokuxhumana nokunqoba izinkinga ekudlulisweni kwezimpawu zebanga elide, kubalulekile ukudlulisa i-spectrum yesignali esiteshini esivame kakhulu ngokusebenzisa ukuguqulwa kwe ...Funda kabanzi -
Imishini eminingi esebenzayo yokuxhumana kwe-fiber optic: ukucushwa nokuphathwa kwama-transceivers e-fiber optic
