1. Rondedzera muchidimbu kuumbwa kweoptical fibers.
A: An optical fiber ine zvikamu zviviri zvakakosha: core uye cladding yakagadzirwa neyakajeka optical material uye cladding.
2. Ndeapi maparamendi akakosha anotsanangura maitiro ekutapurirana kwetambo dzefiber optic?
A: Inosanganisira kurasikirwa, kupararira, bandwidth, cutoff wavelength, mode field dhayamita, nezvimwe.
3. Chii chinokonzera fiber attenuation?
Mhinduro: Fiber attenuation inoreva kuderedzwa kwesimba remaziso pakati pezvikamu zviviri zvemuchinjikwa zvefiber, izvo zvine chokuita newavelength. Zvikonzero zvikuru zvekudzikisira kupararira, kunyura uye kurasikirwa kwemaziso nekuda kwezvibatanidza uye zvimedu.
4. Ko fiber attenuation coefficient inotsanangurwa sei?
Mhinduro: Inotsanangurwa neattenuation (dB / km) pahurefu hweyuniti yeunifomu fiber mune yakatsiga.
5. Chii chinonzi kurasikirwa kwekuisa?
Mhinduro: Inoreva kudzikisira kunokonzerwa nekuiswa kwe optical components (sekuiswa kwezvibatanidza kana macouplers) mutsetse weoptical transmission.
6. Chii chinonzi network bandwidth ine chekuita?optical fiber?
Mhinduro: Iyo bandwidth yefiber inoreva iyo modulation frequency kana amplitude yesimba rekuona iri 50% kana 3dB idiki pane amplitude ye zero frequency mune yekufambisa basa refiber. Iyo bandwidth yefiber optical inenge yakatarisana nekureba kwayo, uye chigadzirwa chehurefu uye bandwidth chinogara chiripo.
