1. Fotokozani mwachidule kapangidwe kakeulusi wa kuwala.
A: Chingwe cha kuwala chimakhala ndi magawo awiri ofunikira: pachimake ndi chotchinga chopangidwa ndi zinthu zowoneka bwino komanso zokutira.
2. Ndi magawo otani omwe amafotokoza za kufalikira kwa mizere ya fiber optic?
A: Zimaphatikizapo kutaya, kubalalitsidwa, bandwidth, cutoff wavelength, mode field diameter, etc.
3. Kodi chimayambitsa kuchepa kwa fiber ndi chiyani?
Yankho: Fiber attenuation imatanthawuza kuchepetsa mphamvu ya kuwala pakati pa zigawo ziwiri za mtanda wa fiber, zomwe zimagwirizana ndi kutalika kwake. Zomwe zimachititsa kuti attenuation ndi kubalalitsidwa, kuyamwa ndi kutayika kwa kuwala chifukwa cha zolumikizira ndi ma splices.
4. Kodi fiber attenuation coefficient imafotokozedwa bwanji?
Yankho: Kutanthauzidwa ndi kuchepa (dB / km) pa unit kutalika kwa yunifolomu ulusi wokhazikika.
5. Kodi kutayika koyika ndi chiyani?
Yankho: Amatanthauza kuchepetsedwa komwe kumachitika chifukwa cha kuyika kwa zigawo za kuwala (monga kuyika kwa zolumikizira kapena ma couplers) mu mzere wa kuwala.
6. Kodi bandwidth ya network ikugwirizana ndi chiyani?kuwala CHIKWANGWANI?
Yankho: Bandiwifi ya fiber imatanthawuza kusinthasintha kwafupipafupi pamene matalikidwe a mphamvu ya kuwala ndi 50% kapena 3dB yaying'ono kuposa matalikidwe a zero pafupipafupi mu ntchito yosinthira ya fiber. Kuthamanga kwa chingwe cha optical ndi pafupifupi mosagwirizana ndi kutalika kwake, ndipo kutalika kwake ndi bandwidth kumakhala kosasintha.
