Optical fiberisa sesebelisoa sa ho tsamaisa leseli se sebelisang molao-motheo oa ho bonahatsa khanya ka botlalo ka fiber e entsoeng ka khalase kapa polasetiki.
Fiber ea Optical bare fiber ka kakaretso e arotsoe ka likarolo tse tharo: mantlha, ho roala le ho roala.
The optical fiber core le cladding li entsoe ka likhalase tsa li-indices tse fapaneng tsa refractive, tse nang le khalase e phahameng ea refractive index (germanium-doped silicon dioxide) bohareng le index e tlase ea silicon e cladding ea khalase (silicon dioxide e hloekileng) bohareng. Leseli le thunngoa ka har'a fiber ka mokhoa o itseng oa Angle, 'me ho hlaha ho tsoa ka ho feletseng pakeng tsa fiber le cladding (hobane index ea refractive ea cladding e tlase hanyenyane ho feta ea mantlha), e le hore e ka ata ka fiber. Mosebetsi o ka sehloohong oa lera la ho roala ke ho sireletsa fiber ho senya ka ntle, 'me ka nako e ts'oanang ho eketsa ho feto-fetoha ha fiber. Joalokaha ho boletsoe pejana, mokokotlo le liphahlo li entsoe ka khalase, e ke keng ea kobeha le ho senyeha, 'me tšebeliso ea lera la ho roala e sireletsa le ho lelefatsa bophelo ba fiber.
E ka holimo ke "mohaho oa fiber" o tlisoang ke HDV PhoelektroneTheknoloji LTD.Khamphani ea rona ke lisebelisoa tse khethehileng tsa marang-rang e le bahlahisi ba ka sehloohong ba tlhahiso, lisebelisoa tse amanang le marang-rang li koahela letoto la OLT, letoto la ONU, letoto la li-switch, letoto la optical module joalo-joalo, le amohelehile ho utloisisa.
