Waveband bakeng sa fiber optical

Puisano ea fiber ea optical e nka leseli joalo ka mojari oa tlhahisoleseling ho buisana.E ka fetisoa ka fiber core.Leha ho le joalo, hase lehlaseli le leng le le leng la leseli le loketseng puisano.Tahlehelo ea phetiso e fapana ho ea ka maqhubu a fapaneng a maqhubu a khanya.Bakeng sa ho fumana tahlehelo e fokolang le ho sebetsa ka katleho, bo-rasaense ba lula ba batla leseli le loketseng ka ho fetisisa.

  • 850nm Waveband

Mathoasong a lilemo tsa bo-1980, bo-rasaense ba ile ba qala ho hlahloba theknoloji ea puisano ea optical fiber ka tsela e sebetsang.Multi-mode fiber ke seo ba neng ba ithuta haholo ka sona.Ka li-cores tse kholoanyane, fiber ea mofuta oa muti e khona ho fumana phetiso e le 'ngoe ea fiber bakeng sa mabone a mofuta oa muti.Leseli la maqhubu a 850nm ke lona le neng le sebelisoa pele.

  • O Waveband

Mathoasong a lilemo tsa bo-1990, fiber ea mofuta o le mong e ile ea qala ho sebelisoa haholo.

Bo-rasaense ba fumane hore khanya ea waveband ea 1260nm ~ 1360nm e ka finyella ho senyeha ho fokolang ha pontšo le tahlehelo ea phetisetso e bakiloeng ke ho hasana ka liteko.Ka liteko le liphoso, bo-rasaense ba fumane hore leseli le nang le 1260nm ~ 1625nm le lona le sebakeng sa tahlehelo e fokolang 'me ke leseli le loketseng ka ho fetisisa bakeng sa phetiso ea fiber.

1260nm ~ 1625nm waveband lebone le arotsoe ka waveband ea maqhubu a mahlano-O, E waveband, S waveband, C waveband le L waveband.

Bo-ramahlale ba boetse ba fumane likamano lipakeng tsa tahlehelo ea phetisetso le bolelele ba maqhubu.E bontša ka tsela e latelang.

Sehlopha se sebelisoang haholo ke C waveband ((1530nm~1565nm), e emelang "tloaelo".Sehlopha sa C se ka finyella tahlehelo e fokolang ea phetisetso e sebelisoang haholo ho MAN, sebaka se selelele, sebaka se selelele sa marang-rang, tsamaiso ea likepe tse tsamaeang ka tlas'a metsi le tsamaiso ea WDM.

  • L Waveband (1565nm~1625nm)

L e emetse “long-wavelength”.L waveband e ka fihlela tahlehelo ea phetisetso ea bobeli e nyane hape ke e 'ngoe ea khetho ea mantlha bakeng sa liindasteri.Haeba C waveband e sa khone ho fihlela litlhoko tsa bandwidth, Hangata Batho ba tla nka L waveband e le tlatsetso.

  • S Waveband (1460nm ~ 1530nm)

S e emetse “short-wavelength”.Ha ho tluoa tabeng ea tahlehelo ea fiber, e phahame ho feta O waveband.Hangata e sebelisoa ho ea tlase wavelength ea PON.

  • E Waveband

Ke waveband e tloaelehileng haholo har'a mefuta e mehlano ea waveband.E e emetse "e atolositsoeng".Joalokaha ho bontšitsoe setšoantšong sa 3, leqhubu le ka bonoa ho E waveband.Ke hobane e ile ea kenngoa ke OH- e lebisang tahlehelong e kholo ea phetisetso, eo hape e bitsoang tlhoro ea metsi.

Mehleng ea khale, ka lebaka la theknoloji e fokolang, metsi a ne a tsoakoa ka khalase ea optical fiber e ileng ea lebisa tahlehelo e kholo ea phetisetso ho E waveband mme e ne e sa khone ho sebetsa ka mokhoa o tloaelehileng.Kamora moo, batho ba ile ba theha theknoloji ea ho felloa ke metsi 'meleng ka ho etsa likhalase, ho tloha ka nako eo, tahlehelo ea phetisetso ho E waveband e ne e le tlase le ho feta O waveband.Leha ho le joalo, tahlehelo ea phetisetso e etsahetse ho E waveband ka thapo ea fiber ea optical e behiloeng pele e hlalosa hore ho ntse ho na le meeli bakeng sa E waveband e sebelisoang puisanong ea fiber optical.

  • U Waveband (ultra-long-long-wavelength, 1625-1675 nm)

Ntle le tsena waveband tse boletsoeng, U waveband e boetse e sebelisoa haholo, haholo ho lekola marang-rang.
