1.optical fiber konokono sebopeho
1) Core: index e phahameng ea refractive, e sebelisetsoang ho fetisa leseli;
2) Ho roala: index e tlase ea refractive, e etsang boemo bo felletseng ba ho bonahatsa le mantlha;
3) Lera le sireletsang: le sireletsa fiber ea optical.
2.Mokhoa o le mong le mefuta e mengata
Ke mokhoa o le mong feela oa khanya o ka fetisoang.Ka hona, ho hasana ha eona ka har'a mefuta-futa ho nyane ebile ho loketse puisano e hole, empa ho boetse ho na le phallo ea lintho tse bonahalang le phallo ea waveguide.Ka tsela ena, fiber ea mofuta o le mong e na le litlhoko tse phahameng bakeng sa bophara ba spectral le botsitso ba mohloli oa leseli, ke hore, bophara ba spectral bo tlameha ho ba bo moqotetsane le botsitso bo Molemo.Fiber ea mofuta o le mong e na le ho hasana hohle.
E ka fetisa mefuta e mengata ea khanya.Leha ho le joalo, phallo ea eona ea li-inter-mode e kholo, e fokotsang makhetlo a mangata a ho fetisa melaetsa ea digital, 'me e tla ba e tebileng le ho feta ka sebaka se ntseng se eketseha.Sebaka sa phetisetso ea fiber ea mefuta e mengata e batla e le khuts'oane, hangata ke lik'hilomithara tse 'maloa feela.
Thepa ea mofuta o le mong hangata e ka sebetsa ho fiber ea mofuta o le mong kapa fiber ea mefuta e mengata, athe lisebelisoa tsa mefuta e mengata li lekanyelitsoe ho sebetsa ka fiber ea mefuta e mengata.
