1. Hlalosa ka bokhutšoanyane sebopeho salikhoele tsa optical.
A: Fibre ea optical e na le likarolo tse peli tsa mantlha: mantlha le li-cladding tse entsoeng ka thepa e bonaletsang ea optical le mokhabiso.
2. Ke lintlha life tsa motheo tse hlalosang litšobotsi tsa phetiso ea likhoele tsa fiber optic?
A: E kenyelletsa tahlehelo, ho hasana, bandwidth, cutoff wavelength, bophara ba tšimo ea mode, joalo-joalo.
3. Sesosa sa fiber attenuation ke eng?
Karabo: Fiber attenuation e bolela ho fokotseha ha matla a optical pakeng tsa likarolo tse peli tsa sefapano sa fiber, tse amanang le bolelele ba maqhubu. Lisosa tse ka sehloohong tsa attenuation ke ho hasana, ho monya le tahlehelo ea mahlo ka lebaka la lihokelo le li-splices.
4. Fiber attenuation coefficient e hlalosoa joang?
Karabo: E hlalosoa ke attenuation (dB / km) ka bolelele ba yuniti ea fiber e ts'oanang e tsitsitseng.
5. Ho lahleheloa ke ho kenya ke eng?
Karabo: E bua ka ho fokotseha ho bakoang ke ho kenngoa ha likarolo tsa optical (tse kang ho kenngoa ha li-connectors kapa li-couplers) moleng oa optical transmission.
6. Marang-rang a marang-rang a amana le eng?fiber ea optical?
Karabo: Bophahamo ba fiber bo bua ka maqhubu a ho feto-fetoha ha matla a matla a optical a le 50% kapa 3dB e nyane ho feta amplitude ea maqhubu a zero mosebetsing oa phetisetso ea fiber. Bophahamo ba fiber ea optical bo batla bo lekana ka tsela e fapaneng le bolelele ba eona, 'me sehlahisoa sa bolelele le sekhahla se lula se le teng.
