Kuyankhulana kwa fiber ndi njira yayikulu yotumizira mauthenga amakono. Mbiri yake yachitukuko ndi zaka khumi kapena ziwiri zokha. Zakhala zikukumana ndi mibadwo itatu: mawonekedwe afupipafupi a multimode fiber, kutalika kwa mawonekedwe a multimode fiber ndi utali wautali wamtundu umodzi. Pakali pano, China kuwala CHIKWANGWANI kulankhula walowa siteji zothandiza. Kuphatikiza apo, maiko ambiri adalengeza kuti sadzamanganso mizere yolumikizirana ndi chingwe ndipo akudzipereka pakupanga kulumikizana kwa fiber.
Chiyambi cha Optical Fiber Communication
Zomwe zimatchedwa optical fiber communication zimagwiritsa ntchito ulusi wa kuwala kufalitsa mafunde owala onyamula uthenga kuti akwaniritse zolinga zoyankhulirana. Kuti apange kuwala kwa mafunde chonyamulira chonyamulira zidziwitso, ziyenera kusinthidwa, ndipo chidziwitsocho chimapezeka kuchokera ku kuwala kwa kuwala pamapeto olandira. anasintha kotheratu nkhope ya kuyankhulana kwa dziko, ndipo chitukuko chake chamtsogolo sichingatheke.
Mfundo yolumikizirana ndi ma fiber optical
Mfundo yolumikizana ndi kuwala kwa fiber: pamapeto otumizira, chidziwitso chotumizidwa (monga mawu) chimasinthidwa kukhala chizindikiro chamagetsi, kenako chimasinthidwa pamtengo wa laser womwe umatulutsidwa ndi laser, kuti mphamvu ya kuwala isinthe ndi matalikidwe (mafupipafupi) a siginecha yamagetsi, ndi Tumizani kudzera mu ulusi. Pamapeto olandila, chowunikira chimalandira chizindikiro cha kuwala ndikuchitembenuza kukhala chizindikiro chamagetsi, chomwe chimachotsedwa kuti chibwezeretse chidziwitso choyambirira.
Ubwino
(1) Mphamvu yolumikizirana ndi yayikulu ndipo mtunda wotumizira ndi wautali.
(2) Kutayika kwa fiber kumakhala kochepa kwambiri.
(3) Kusokoneza chizindikiro chaching'ono ndi chinsinsi chabwino.
(4) Kusokoneza kwa Anti-electromagnetic, kufalikira kwabwino.
(5) Ulusiwu ndi wocheperako komanso wopepuka, womwe ndi wosavuta kuuyika ndikuwunyamula.
(6) Wolemera muzinthu komanso kuteteza chilengedwe, ndizothandiza kupulumutsa mkuwa wachitsulo wopanda chitsulo.
(7) Palibe ma radiation, ndizovuta kumva.
(8) Chingwechi chimakhala ndi mphamvu zosinthika komanso moyo wautali.
Kuipa
(1) Maonekedwe ake ndi ophwanyika ndipo mphamvu zamakina ndizosauka.
(2) Kudula ndi kuphatikizika kwa ulusi wa kuwala kumafuna zida, zida ndi njira zina.
(3) Kugawanika ndi kugwirizana sikusinthasintha.
(4) Kupindika kwa chingwe cha fiber optic sikuyenera kukhala kochepa kwambiri (> 20cm).
(5) Pali vuto la kulephera kwa magetsi.
Kuneneratu kwachitukuko cha optical fiber communication
Masiku ano, kuchuluka kwa malonda a zida zoyankhulirana za optical fiber ndi chingwe cha kuwala ku China chikuwonjezeka chaka chilichonse. M'madera ambiri akumidzi a zigawo ndi mizinda yambiri ku China, ntchito yomanga mauthenga a m'manja idakali yopanda kanthu. Kuphatikiza apo, ndi chitukuko cha ntchito za Broadband komanso kufunikira kwa kukulitsa maukonde, kulumikizana kwamtsogolo kwa fiber fiber Msika ndi waukulu.
