Fiber ea Optical
Kenyelletso ea Sehlahisoa
Optical Fiber e entsoe ka likhoele tsa khalase kapa tsa polasetiki tse fetisang data joalo ka mahlaseli a khanya, e fanang ka lebelo le phahameng haholo la phetisetso ea data. E ka tsamaisa lintlha tse ngata libakeng tse telele ka tahlehelo e fokolang ea matšoao. Ho fapana le likhoele tsa khale tsa koporo, Fiber ea Optical ha e khone ho kena-kenana le tšitiso ea motlakase le tšitiso ea radiofrequency, e netefatsang lets'oao le hloekileng le le tšepahalang. Boleng bona bo etsa hore Optical Fiber e be khetho e nepahetseng bakeng sa likhokahano tsa mehala le likhokahano tsa nako e telele.
Re fana ka mefuta e fapaneng ea lihlahisoa tsa fiber optical, ho kenyelletsa le G.652.D, G.657.A1, G.657.A2, le tse ling tse ngata ho fana ka litlhoko tsa hau tse khethehileng.
litšobotsi
Optical fiber eo re faneng ka eona e na le litšobotsi tse latelang:
1) Khetho e feto-fetohang ea liphahlo tse fapaneng ho fihlela litlhoko tsa liketsahalo tse fapaneng tsa kopo.
2)Small polarization mode dispersion coefficient, e loketseng bakeng sa phetiso ea lebelo le phahameng.
3) Ho hanyetsa mokhathala ho matla, ho loketse ho sebelisoa libakeng tse fapaneng.
Kopo
Haholo-holo e sebelisoa mefuteng e fapaneng ea thapo ea optical ho bapala karolo ea puisano.
