Kodi Mzere Wochedwa wa Fiber Optic (OFDL) ndi chiyani?

Kodi Ulusi ndi Chiyani?Mzere Wochedwa wa OpticOFDL

CHIKWANGWANI Kuwala Kuchedwa Mzere(OFDL) ndi chipangizo chomwe chingathe kuchedwetsa nthawi ya ma signal a kuwala. Pogwiritsa ntchito kuchedwetsa, chimatha kukwaniritsa kusintha kwa gawo, kusungirako zonse ndi ntchito zina. Chili ndi ntchito zosiyanasiyana mu radar ya magawo, njira zolumikizirana za fiber optic, njira zotsutsana zamagetsi, kafukufuku wasayansi ndi mayeso, ndi madera ena. Nkhaniyi iyamba kuchokera ku mfundo zoyambira za mizere yochedwa ya fiber optic, kuyang'ana kwambiri zochitika zogwiritsira ntchito komanso momwe mungasankhire mzere woyenera wa fiber optic delay.
Mfundo yogwirira ntchito
Mfundo yaikulu ya mzere wochedwa wa fiber optic ndi yakuti chizindikiro cha kuwala chomwe chiyenera kuchedwa chimatumizidwa kudzera mu utali winawake wa chingwe cha fiber optic, ndipo chifukwa cha nthawi yomwe imafunika kuti kuwala kutumizidwe mu chingwe cha fiber optic, kuchedwa kwa nthawi kwa chizindikiro cha kuwala kumachitika. Monga momwe zasonyezedwera pa Chithunzi 1, mzere wochedwa wa fiber optic ndi dongosolo lopangidwa ndi zipangizo monga ma laser, ma modulators, ma transmission fiber, ndi ma photodetectors okhala ndi ntchito yochedwa kwa chizindikiro. Mfundo yogwirira ntchito: Chizindikiro cha RF chomwe chiyenera kutumizidwa ndi chizindikiro cha kuwala chomwe chimachokera ku laser zimalowetsedwa mu ma modulators osiyanasiyana. Ma modulators amasintha chizindikiro cha RF kupita ku kuwala kuti apange chizindikiro cha kuwala chomwe chimanyamula chidziwitso cha RF. Chidziwitso cha RF chomwe chimanyamula chizindikiro cha kuwala chimalumikizidwa ndi ulalo wa fiber optic kuti chitumizidwe, chimachedwa kwa nthawi, kenako chimafika pachowunikira zithunziChowunikira zithunzi chimasintha chizindikiro cholandirira cha kuwala chomwe chili ndi chidziwitso cha RF kukhala chizindikiro chamagetsi.

Chithunzi 1 Kapangidwe Koyambira kaMzere Wochedwa wa CHIKWANGWANI cha OpticOFDL

Zochitika zogwiritsira ntchito
1. Radar ya magawo: Gawo lalikulu la radar ya magawo ndi antenna ya magawo. Ma antenna achikhalidwe a radar sakwaniritsa zofunikira za machitidwe a radar, pomwe mizere ya fiber optic delay ili ndi ubwino wawo wapadera pakugwiritsa ntchito ma antenna a magawo. Chifukwa chake, mizere ya fiber optic delay ili ndi tanthauzo lalikulu la sayansi mu radar ya magawo.
2. Dongosolo lolumikizirana ndi fiber optic: Mizere yochedwa ya fiber optic ingagwiritsidwe ntchito kukhazikitsa njira zinazake zolembera. Mwa kuyambitsa kuchedwa kosiyanasiyana nthawi zosiyanasiyana, ma siginecha okhala ndi mapatani enaake amatha kupangidwa, zomwe zimathandiza pakukweza mphamvu yoletsa kusokoneza ma siginecha mumakina olumikizirana a digito. Kuphatikiza apo, ingagwiritsidwenso ntchito ngati malo osungira kwakanthawi (cache) kuti isunge deta inayake kwakanthawi, ndi zina zotero. Mwachidule, mizere yochedwa ya fiber optic ili ndi ntchito zambiri m'magawo ambiri chifukwa cha kuchuluka kwa bandwidth, kutayika kochepa, komanso kukana kusokonezedwa ndi ma elekitiromagineti. Kaya m'magawo olumikizirana, radar, navigation, kapena medical imaging, onsewa amachita ntchito zofunika kwambiri.
