I-fiber ebonakalayo iyintambo encane, eguquguqukayo, nebonakalayo eyenziwe ngengilazi noma ipulasitiki ehlanzekile kakhulu edlulisela idatha ngesimo sama-pulse okukhanya. Ngokungafani nezintambo zethusi zendabuko, ezisebenzisa izimpawu zikagesi, i-optical fiber isebenzisa ukukhanya, okuvame ukukhiqizwa ngama-laser noma ama-LED.

I-fiber ejwayelekile ye-optical inezingqimba ezintathu eziyinhloko:

• Ingqikithi: Isifunda esiphakathi lapho ukukhanya kuhamba khona
• Ukubopha: Ingqimba ezungeze ingaphakathi elibonisa ukukhanya emuva enkabeni
• Isimbozo/I-Buffer: Isendlalelo esivikelayo ukuvimbela umonakalo kanye nokuphazamiseka komswakama

Lesi sakhiwo siqinisekisa ukuthi izimpawu zokukhanya zihlala ngaphakathi kwefayibha ngenqubo ebizwa ngokuthi ukubonakaliswa kwangaphakathi okuphelele.

Indlela I-Optical Fiber Esebenza Ngayo

Isimiso sokusebenza se-optical fiber sisekelwe ku-physics kanye nokusabalala kokukhanya.

Ukuzindla Kwangaphakathi Okuphelele

Uma ukukhanya kungena enkabeni yefayibha nge-engeli ethile, kukhanya njalo ngaphakathi enkabeni esikhundleni sokuphuma. Lokhu kuvumela izimpawu ukuthi zihambe amabanga amade ngokulahlekelwa okuncane.

Ukudluliselwa Kokukhanya

Idatha iguqulwa ibe ama-pulse okukhanya kusetshenziswa:

• Ama-diode e-laser (okuxhumana okude, okusheshayo)
• Ama-LED (okuxhumana ibanga elifushane)

Lawa ma-pulse amelela idatha ye-binary (0 kanye no-1), eqoshwa ekugcineni kokwamukela.

Ukwamukelwa Kwesignali

Lapho uya khona, i-photodetector iguqula ukukhanya kube amasignali kagesi, abese ecutshungulwa njengedatha (i-inthanethi, izwi, noma ividiyo).
