1. Chaza ngokufutshane ukwakhiwa kweiintsinga zamehlo.
IMPENDULO: Ifiber ebonakalayo inamalungu amabini asisiseko: undoqo kunye nesigqubuthelo esenziwe ngezinto ezibonakalayo ezibonakalayo kunye nezigqubuthelo.
2. Ziziphi iiparamitha ezisisiseko ezichaza iimpawu zothumelo lwemigca yefiber optic?
A: Ibandakanya ilahleko, ukusasazwa, i-bandwidth, i-cutoff wavelength, i-mode field diameter, njl.
3. Yintoni unobangela wefiber attenuation?
Impendulo: I-Fiber attenuation ibhekisela ekunciphiseni amandla okukhanya phakathi kwamacandelo amabini anqamlezayo e-fiber, ehambelana nobude be-wavelength. Ezona zizathu ziphambili zokuthomalalisa kukusasazwa, ukufunxwa kunye nokulahleka kwamehlo ngenxa yezihlanganisi kunye neziqwenga.
4. Ichazwa njani i-fiber attenuation coefficient?
Impendulo: Ichazwe ngokunciphisa (dB/km) ngobude beyunithi yefiber efanayo kwisimo esizinzileyo.
5. Yintoni ilahleko yokufaka?
Impendulo: Ibhekisela ekunciphiseni okubangelwa ukufakwa kwezinto ezibonakalayo (ezifana nokufakwa kwezihlanganisi okanye i-couplers) kumgca wokuhanjiswa kwe-optical.
6. Yintoni i-bandwidth yenethiwekhi enxulumene nayo?i-fiber optical?
Impendulo: I-bandwidth yefiber ibhekisela kwi-modulation frequency xa i-amplitude yamandla optical i-50% okanye i-3dB encinci kune-amplitude ye-frequency zero kumsebenzi wokudlulisa i-fiber. I-bandwidth ye-fiber optical iphantse ihambelane nobude bayo, kwaye imveliso yobude kunye ne-bandwidth ihlala njalo.
