1. Chaza ngokufutshane indlela ekwakhiwe ngayo iifayibha ezibonakalayo.
A: I-fiber ye-optical inamacandelo amabini asisiseko: umbindi kunye ne-cladding eyenziwe ngezinto ezibonakalayo ezibonakalayo kunye ne-coating.
2. Ziziphi iiparameter ezisisiseko ezichaza iimpawu zokudluliselwa kwemigca ye-fiber optic?
A: Ibandakanya ukulahleka, ukusasazwa, i-bandwidth, ubude bexesha obunqumlekileyo, ububanzi bentsimi ye-modal, njl.
3. Yintoni ebangela ukuncitshiswa kwefayibha?
Impendulo: Ukuncitshiswa kwefayibha kubhekisa ekunciphiseni amandla okukhanya phakathi kwamacandelo amabini anqamlezileyo efayibha, enxulumene nobude be-wavelength. Izizathu eziphambili zokuncitshiswa kukusasazwa, ukufunxwa, kunye nokulahleka kwe-optical ngenxa yezihlanganisi kunye nee-splices.
4. Ichazwa njani i-fiber attenuation coefficient?
Impendulo: Ichazwa kukunciphisa (dB/km) ngobude beyunithi nganye yefayibha efanayo kwisimo esingaguqukiyo.
5. Yintoni ilahleko yokufaka?
Impendulo: Ibhekisa ekuncipheni okubangelwa kukufakwa kwezinto ezibonakalayo (ezifana nokufakwa kwezihlanganisi okanye ii-couplers) kumgca wokudlulisela we-optical.
6. Inxulumene nantoni i-bandwidth? i-fiber optics?
Impendulo: I-bandwidth yefayibha ibhekisa kwi-modulation frequency xa i-amplitude yamandla okukhanya ingaphantsi kwe-50% okanye i-3 dB kune-amplitude ye-zero frequency kumsebenzi wokudlulisa ifayibha. I-bandwidth yefayibha optical iphantse ilingane nobude bayo, kwaye imveliso yobude kunye ne-bandwidth ayiguquki.
