1. E wehewehe pōkole i ka haku ʻana o kanā lau ʻōpika.
A: ʻElua mau ʻāpana kumu o ka fiber optical: ʻo ke kumu a me ka pale i hana ʻia me nā mea optical a me ka pale.
2. He aha nā ʻāpana kumu e wehewehe i nā hiʻohiʻona hoʻouna o nā laina fiber optic?
A: Loaʻa iā ia ka poho, dispersion, bandwidth, cutoff wavelength, mode field diameter, etc.
3. He aha ke kumu o ka attenuation fiber?
Pane: ʻO ka attenuation fiber e pili ana i ka hoʻemi ʻana o ka mana optical ma waena o nā ʻāpana keʻa ʻelua o kahi fiber, pili i ka lōʻihi hawewe. ʻO nā kumu nui o ka attenuation ʻo ia ka dispersion, absorption a me nā nalowale optical ma muli o nā mea hoʻohui a me nā splices.
4. Pehea ka wehewehe ʻana i ka coefficient attenuation fiber?
Pane: Ua wehewehe ʻia e ka attenuation (dB/km) no kēlā me kēia ʻāpana lōʻihi o ke kaula like ʻole i ke kūlana paʻa.
5. He aha ka poho hoʻokomo?
Pane: E pili ana ia i ka attenuation i hoʻokomo ʻia e ka hoʻokomo ʻana i nā ʻāpana optical (e like me ka hoʻokomo ʻana o nā mea hoʻohui a i ʻole nā mea hoʻohui) i loko o ka laina hoʻoili optical.
6. He aha ka pili o ka bandwidth pūnaewele?puluniu maka?
Pane: ʻO ka bandwidth o ka fiber e pili ana i ke alapine modulation i ka wā o ka amplitude o ka mana optical he 50% a i ʻole 3dB ka liʻiliʻi ma mua o ka amplitude o ke alapine zero i ka hana hoʻoili o ka fiber. ʻO ka bandwidth o kahi fiber optical e like me ka like ʻole i kona lōʻihi, a ʻo ka huahana o ka lōʻihi a me ka bandwidth he mau.
