1. E wehewehe pōkole i ke ʻano o ka hoʻonohonoho ʻana o nā olonā ʻike maka.
A: ʻO kahi olonā optical he ʻelua mau ʻāpana nui: ke kumu a me ka uhi ʻana i hana ʻia me ka mea optical moakaka a me ka uhi ʻana.
2. He aha nā ʻano kumu e wehewehe ana i nā ʻano hoʻoili o nā laina fiber optic?
A: Hoʻokomo pū ʻia ka pohō, ka hoʻopuehu ʻana, ka bandwidth, ka nalu ʻokiʻoki, ke anawaena kahua modal, a pēlā aku.
3. He aha ke kumu o ka emi ʻana o ka fiber?
Pane: ʻO ka attenuation fiber e pili ana i ka hōʻemi ʻana o ka mana optical ma waena o ʻelua mau ʻāpana kea o kahi fiber, e pili ana i ka wavelength. ʻO nā kumu nui o ka attenuation ka hoʻopuehu ʻana, ka absorption, a me nā pohō optical ma muli o nā mea hoʻohui a me nā splices.
4. Pehea e wehewehe ʻia ai ke koina attenuation fiber?
Pane: Ho'ākāka 'ia e ka attenuation (dB/km) no kēlā me kēia anakahi lōʻihi o kahi fiber like ma ke kūlana paʻa.
5. He aha ka pohō hoʻokomo?
Pane: Pili ia i ka attenuation i hoʻokumu ʻia e ka hoʻokomo ʻana o nā ʻāpana optical (e like me ke komo ʻana o nā mea hoʻohui a i ʻole nā mea hoʻohui) i loko o ka laina hoʻoili optical.
6. He aha ka mea e pili ana i ka bandwidth? nā ʻike maka fiber?
Pane: ʻO ka bandwidth fiber e pili ana i ke alapine modulation ke emi ka amplitude mana optical ma mua o ka amplitude alapine zero i ka hana hoʻoili o ka fiber. ʻO ka bandwidth o kahi fiber optical e pili pono ana i kona lōʻihi, a ʻo ka huahana o ka lōʻihi a me ka bandwidth he mau.
