Ua ntej nyob rau hauv Tsawg Dej Peak Fibers

Hauv kev sib txuas lus hauv ntiaj teb, kev txhim kho ntawm cov dej tsis tshua muaj siab (LWP) uas tsis yog-dispersion-hloov ib hom fiber ntau tau ua rau muaj kev sib tsoo, thiab yog vim li cas. Txoj kev kho qhov muag fiber ntau no yog tsim los rau kev sib txuas lus ua haujlwm nyob rau hauv tag nrho cov zaus band los ntawm 1280nm txog 1625nm, thiab muaj kev ua tau zoo dua qub piv rau cov khoom siv kho qhov muag.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov fiber ntau tshiab no yog nws lub peev xwm los tswj kom tsis txhob muaj qhov sib txawv ntawm cov tsoos 1310nm band thaum pom qhov poob qis hauv 1383nm band. Qhov tshwj xeeb no tso cai rau kev siv tag nrho ntawm E-band, uas nyob ntawm 1360nm txog 1460nm. Raws li qhov tshwm sim, telcos thiab cov neeg ua haujlwm hauv lub network muaj kev cia siab txog kev siv thev naus laus zis muaj peev xwm cuam tshuam rau lawv lub tshuab.

Qhov cuam tshuam ntawm txoj kev loj hlob ntawm LWP tsis-dispersion hloov ib hom fiber ntau yog nyob deb. Los ntawm kev siv tag nrho E-band, qhov fiber ntau no qhib lub sijhawm tshiab los ua kom muaj peev xwm thiab ua tau zoo ntawm kev sib txuas lus kho qhov muag. Qhov kev nce qib no los ntawm lub sijhawm tseem ceeb thaum lub network infrastructure tab tom ntsib nws cov kev txwv raws li qhov kev thov rau cov ntaub ntawv ceev ceev txuas ntxiv mus ntxiv.

Qhov kev cia siab no yog qhov zoo siab tshwj xeeb rau kev lag luam xws li cov chaw zov me nyuam cov ntaub ntawv, kev sib txuas lus thiab cov chaw muab kev pabcuam hauv internet, txhua yam yuav tau txais txiaj ntsig los ntawm kev txhim kho cov peev txheej no. Tsis tas li ntawd, lub peev xwm rau kev txhim kho kev ua haujlwm ntawm lub cev thiab txo cov teeb liab attenuation nyob rau ntau qhov dav ntawm wavelengths yog ib qho kev xav zoo rau cov neeg koom nrog hauv kev xa tawm ntawm kev sib txuas lus kho qhov muag.

Raws li kev lag luam kev sib txuas lus txuas ntxiv txhim kho thiab qhov kev thov rau cov ntaub ntawv ceev ceev sib kis tau nce ntxiv, txoj kev loj hlob zeem muag ntawm cov dej qis-peak uas tsis yog-dispersion-hloov ib hom optical fiber ntau sawv cev rau lub sijhawm tseem ceeb. Cov lus cog tseg ntawm kev muaj peev xwm sib kis tau ntxiv thiab kev siv tag nrho ntawm E-band ua rau qhov fiber ntau no hloov pauv, ua rau lub sijhawm tshiab ntawm kev ua tau zoo thiab muaj peev xwm hauv kev sib txuas lus kho qhov muag. Peb lub tuam txhab kuj tau cog lus rau kev tshawb fawb thiab tsim khoomTsawg dej ncov tsis-dispersive hloov chaw ib hom fiber ntau, yog tias koj txaus siab rau peb lub tuam txhab thiab peb cov khoom, koj tuaj yeem tiv tauj peb.
