Lipontšo tsa bohlokoa tsa melapo ea ho lieha ha fiber optic

Moleng oa ho lieha ha fiber-optic, matšoao a ka sehloohong a tekheniki a karolo ea ho kenya ke boholo ba pontšo ea ho kenya, mefuta e matla, maqhubu a ts'ebetso, bandwidth, amplitude, phase, input VSWR; matšoao a mantlha a tekheniki a karolo ea tlhahiso ke makhetlo a ts'ebetso, nako ea ho lieha, ho nepahala, palo ea lerata, tahlehelo, voltage VSWR, ho feto-fetoha ha mohato oa amplitude. Ho phaella moo, ho na le matšoao a ka ntle, a kang mocheso oa ho sebetsa, mongobo, likarolo tse tharo tse khahlanong le tšireletso, mocheso oa polokelo, foromo ea sebopeho, foromo ea phepelo ea matla. 1, maqhubu a ts'ebetso: e ka koahela sehlopha sa P / L / S / C / X / K. 2, tahlehelo ea phallo: karo-karolelano ea matla a lets'oao la tlhahiso ho matla a lets'oao. Litahlehelo tsena li fokotsoa haholo ke phello ea quantum ea laser le photodetector. 3, nako ea ho lieha: nako ea ho lieha e khethoa haholo ke bolelele ba fiber. 4, mefuta e fapaneng ea matla: ke karo-karolelano ea lets'oao le phahameng la tlhahiso le lets'oao le tlase, matla a lets'oao a phahameng P a tlas'a tšusumetso e kholo ea ho kenya laser (e tsamaellanang le boholo ba 80% ea modulation ea amplitude) le mefokolo ea matla a matla a laser. 5, khatello ea harmonic: sesosa se ka sehloohong sa moloko oa harmonic ke ka lebaka la mojaro o sa tloaelehang. Ha motlakase o phalla ka mojaro, 'me motlakase o sebelisoang ha o na moeli, ho thehoa ha hona joale ho se nang sinusoidal, kahoo ho hlahisa li-harmonics. Tšilafalo ea Harmonic tsamaisong ea matla ke kotsi e tebileng, nka mehato ea ho arabela ho thibela ho fokotsa kotsi ea eona, sena ke khatello ea harmonic.
