Kulankhulana kwa Fiber Optical
Ukadaulo waukadaulo wolumikizirana wama fiber watuluka kuchokera ku kulumikizana kwa kuwala ndipo wakhala chimodzi mwazambiri za kulumikizana kwamakono.Zimagwira ntchito yofunika kwambiri pamagulu amakono a telecommunication.Monga teknoloji yomwe ikubwera, optical fiber communication yakula mofulumira m'zaka zaposachedwa ndipo imagwiritsidwa ntchito kwambiri m'mbiri ya kulankhulana.Ndi chizindikiro chofunikira cha kusintha kwatsopano kwaukadaulo wapadziko lonse lapansi komanso chida chachikulu chotumizira mauthenga osiyanasiyana m'tsogolomu.
Makhalidwe a optical fiber communication
1.Kuchuluka kwa chidziwitso cha Broadband ndi kwakukulu
Mphamvu yolumikizirana ndi kuwala kwa fiber ndi yayikulu, ndipo kufalikira kwa ulusi wa kuwala kumakhala kokulirapo kuposa m'lifupi mwa chingwe kapena waya wamkuwa.Komabe, kwa mawonekedwe amtundu umodzi wa optical fiber, popeza chipangizo chogwiritsira ntchito chimakhala chochepa kwambiri, kufalikira kwa kuwala kwa fiber nthawi zambiri sikuwonetsedwa.Chifukwa chake, njira zasayansi zimafunikira kuti muwonjezere mphamvu yakufalitsa.
2.Kutayika kochepa, kungathe kufalikira pamtunda wautali
Kutayika kwa kuyankhulana kwa fiber optical ndi kotsika kwambiri kusiyana ndi kutayika kwa mauthenga wamba.Ulusi wa kuwala sikuti umangotayika pang'ono, komanso umatha kulankhulana pamtunda wautali.Mtunda wautali kwambiri wolankhulana ukhoza kufika mamita oposa 10,000, kotero kuti kuyankhulana kwa fiber ndi kothandiza kwambiri pa malo ochezera a pa Intaneti.Malo omwe kuchuluka kwa chidziwitso kumayerekezedwa komanso mtengo wolumikizirana ndi fiber-optic ndi wokwera, wokhala ndi chitetezo chabwino.
3.Kusokoneza kwamphamvu kwa anti-electromagnetic
Ulusi wa kuwala makamaka ndi insulator yopangidwa ndi quartz ngati zopangira, ndipo zinthuzo zimakhala zabwino kwambiri pakutchinjiriza ndipo sizimawonongeka mosavuta.Chofunika kwambiri pakulankhulana kwa fiber ndi mphamvu yake yolimbana ndi ma electromagnetic interference, ndipo sichoncho. kukhudzidwa ndi zochitika zachilengedwe za sunspot, kusintha kwa ionospheric ndi kusokonezedwa kwa mphezi, ndipo sikukhudzidwa ndi kusokonezedwa kwa magetsi opangira magetsi. chingwe chamagetsi.Chikhalidwe ichi cha optical fiber communication chimakhala ndi gawo lalikulu mu njira yolankhulirana m'munda wa mphamvu yamphamvu yamagetsi.Kulankhulana kwamphamvu kwamagetsi kumatha kugwiritsidwanso ntchito kwa asitikali chifukwa kumatha kukhala kopanda kusokonezedwa ndi ma electromagnetic pulse.
4.Chitetezo chabwino ndi chinsinsi
Potumiza mafunde a wailesi m'mbuyomo, popeza mafunde a electromagnetic amatuluka panthawi yopatsirana, kusokoneza kwa machitidwe osiyanasiyana opatsirana kumayambitsa, ndipo chinsinsi sichili chabwino.Zizindikiro zowoneka bwino zimangokhazikika pamapangidwe a mawonekedwe a optical waveguide, ndipo kuwala kwina kotayikira kumatengedwa ndi mchira wakunja wa fiber fiber, ngakhale mu mphete yokhala ndi vuto loyipa kapena ngodya.Palinso kutayikira kwa mafunde ochepa.Kuphatikiza apo, polumikizana ndi ma optical fiber, zingwe zambiri zama fiber zimatha kuyikidwa mu chingwe chimodzi cholumikizira popanda kusokoneza.Choncho, kuyankhulana kwa fiber optical kumakhala ndi mphamvu zotsutsana ndi kusokoneza komanso chinsinsi, ndipo chitetezo cha optical fiber communication chimakhalanso chapamwamba kwambiri.
