Ka ho kenngoa ha fiber ea optical, tekanyo e nepahetseng le ho bala li-link tsa optical fiber ke mohato oa bohlokoa haholo ho netefatsa botšepehi ba marang-rang le ho netefatsa ts'ebetso ea marang-rang. Fiber ea optical e tla baka tahlehelo e hlakileng ea matšoao (ke hore, tahlehelo ea optical fiber) ka lebaka la ho kenngoa ha leseli le ho hasana, e leng ho tla ama ho tšepahala ha marang-rang a optical transmission. Joale re ka tseba joang boleng ba tahlehelo ho sehokelo sa fiber? Sengoliloeng sena se tla u ruta mokhoa oa ho bala tahlehelo ho likhokahano tsa fiber optic le mokhoa oa ho ahlola ts'ebetso ea likhokahano tsa fiber optic.
Mofuta oa tahlehelo ea fiber: Tahlehelo ea fiber e boetse e tsejoa e le ho fokotsa leseli, ho bolelang palo ea tahlehelo ea leseli pakeng tsa pheletso e fetisang le pheletso e amohelang fiber. Ho na le mabaka a mangata a tahlehelo ea fiber ea optical, joalo ka ho monya / ho hasanya ha matla a khanya, tahlehelo ea ho kobeha, tahlehelo ea sehokelo, jj.
Ho akaretsa, ho na le mabaka a mabeli a ka sehloohong a ho lahleheloa ke fiber ea optical: lintlha tse ka hare (ke hore, litšobotsi tsa tlhaho tsa fiber optical) le lintlha tse ka ntle (ke hore, tse bakoang ke ts'ebetso e sa lokelang ea optical fiber), e ka aroloa ka intrinsic optical. tahlehelo ea fiber le tahlehelo e seng ea kahare ea fiber ea optical. Tahlehelo ea fiber ea kahare ke mofuta oa tahlehelo ea tlhaho ea thepa ea fiber, e kenyelletsang tahlehelo ea ho monya, tahlehelo ea ho hasana le tahlehelo e hasaneng e bakoang ke bofokoli ba sebopeho. Tahlehelo e seng ea kahare ea fiber e kenyelletsa tahlehelo ea welding, tahlehelo ea sehokelo le tahlehelo ea ho kobeha.
Standards for Fiber Loss: The Telecommunications Industry Alliance (TIA) le Electronic Industry Alliance (EIA) li ile tsa sebetsa 'moho ho nts'etsapele maemo a EIA/TIA, a hlalosang litlhoko tsa ts'ebetso le phetisetso ea lithapo tsa optical le likhokahano 'me joale li se li amohetsoe le ho sebelisoa ka bongata. indasteri ea fiber optic. Litekanyetso tsa EIA/TIA li hlakisa hore ho fokotseha ho hoholo ke e 'ngoe ea litekanyo tsa bohlokoahali ho metha ea tahlehelo ea fiber.
