Sebopeho sa mantlha sa thapo ea optical hangata se entsoe ka mohala oa thapo, terata ea tšepe e matlafalitsoeng, sethapo le sheath.Ho feta moo, ho na le likarolo tse ling tse kang lera le sa keneleng metsi, lera la buffer le lithapo tsa tšepe tse sirelelitsoeng ha ho hlokahala.Mohala oa optical o entsoe ka mokokotlo o matlafalitsoeng le mokokotlo oa cable, sheath le sheath e ka ntle.Ho na le mefuta e 'meli ea mohaho oa li-cable core: mofuta o le mong oa motheo le oa mefuta e mengata: mofuta o le mong o na le mefuta e' meli: mofuta o feletseng le mofuta oa li-tube bundle;mefuta e mengata ea mantlha e na le mefuta e 'meli: ribone le mofuta oa yuniti.Sekhahla sa ka ntle se na le mefuta e 'meli ea lihlomo tsa tšepe le tse se nang lihlomo.
Ts'ebetso ea tlhahiso ea thapo ea optical hangata e arotsoe ka mekhoa e latelang:
1. Ho hlahlojoa ha fiber ea optical: khetha fiber ea optical e nang le litšobotsi tse ntle tsa phetisetso le tsitsipano e tšoanelehang.
2. Ho silafatsoa ha fiber ea optical: Sebelisa chromatogram e felletseng ho tšoaea, e sa hlokeng ho fifala le ho falla ha mocheso o phahameng.
3. Extrusion ea bobeli: sebelisa polasetiki e nang le modulus e phahameng ea elastic le coefficient e tlase ea katoloso ea linear hore e fetisetsoe ka har'a tube ea boholo bo itseng, kenya fiber ka har'a gel e thibelang mongobo le e sa keneleng metsi, 'me u e boloke matsatsi a seng makae (e seng ka tlase ho a mabeli. matsatsi).
4. Mohala oa optical o sothehileng: sotha likhoele tse 'maloa tsa extruded optical ka unit e matlafalitsoeng.
5. Penya lesela le ka ntle la mohala oa optical: eketsa lera la sheath ho cable e sothehileng ea optical.
