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 khanya e 'ngoe le e 'ngoe ea leseli e 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".C sehlopha se ka finyella tahlehelo e fokolang ea phetisetso e sebelisoang haholo ho MAN, sebaka se selelele, sebaka se selelele sa ho qetela, 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.Ka mor'a moo, batho ba ile ba hlahisa theknoloji ea ho ntša metsi 'meleng ka ho etsa likhalase, ho tloha ka nako eo, tahlehelo ea phetisetso ho E waveband e ne e le tlaase 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.
