1. Chaza kafushane ukwakheka kweimicu ye-optical.
A: I-optical fiber iqukethe izingxenye ezimbili eziyisisekelo: i-core kanye ne-cladding eyenziwe ngezinto ezibonakalayo ezibonakalayo kanye nesigqoko.
2. Yimaphi amapharamitha ayisisekelo achaza izici zokudlulisela zemigqa ye-fiber optic?
A: Kufaka phakathi ukulahlekelwa, ukuhlakazeka, umkhawulokudonsa, ubude begagasi be-cutoff, ububanzi benkambu yemodi, njll.
3. Iyini imbangela ye-fiber attenuation?
Impendulo: I-fiber attenuation ibhekisela ekuncishisweni kwamandla optical phakathi kwezingxenye ezimbili eziphambanayo zefayibha, okuhlobene nobude begagasi. Izimbangela eziyinhloko zokunciphisa ukuhlakazeka, ukumuncwa kanye nokulahlekelwa kwamehlo ngenxa yezixhumi neziqephu.
4. Ichazwa kanjani i-fiber attenuation coefficient?
Impendulo: Kuchazwa ukuncipha (dB/km) ngobude beyunithi ngayinye yefayibha eyunifomu esesimweni esizinzile.
5. Kuyini ukulahlekelwa kokufaka?
Impendulo: Ibhekisela ekuncipheni okubangelwa ukufakwa kwezingxenye ze-optical (njengokufakwa kwezixhumi noma ama-couplers) emugqeni wokudlulisa amehlo.
6. Yini ehlobene nomkhawulokudonsa wenethiwekhi?i-fiber optical?
Impendulo: I-bandwidth ye-fiber ibhekisela ku-modulation frequency lapho i-amplitude yamandla optical ingama-50% noma i-3dB encane kune-amplitude ye-frequency zero emsebenzini wokudlulisa we-fiber. I-bandwidth ye-fiber optical icishe ilingane nobude bayo, futhi umkhiqizo wobude nomkhawulokudonsa uhlala njalo.
