Nyob zoo, cov nyeem ntawv thiab cov neeg nyiam siv thev naus laus zis! Hnub no, peb pib taug kev mus rau hauv keeb kwm thiab cov ntsiab lus tseem ceeb ntawm kev siv thev naus laus zis fiber ntau. Ua ib qho ntawm cov neeg muab khoom siv fiber ntau tshaj plaws, OWCable tau nyob rau pem hauv ntej ntawm kev lag luam zoo kawg no. Cia peb kawm txog kev hloov pauv ntawm cov thev naus laus zis tshiab no thiab nws cov ntsiab lus tseem ceeb.
Kev Yug Los Ntawm Fiber Optics
Lub tswv yim ntawm kev coj lub teeb hla lub nruab nrab pob tshab tau pib txij li xyoo pua 19th, nrog rau kev sim thaum ntxov uas siv cov pas iav thiab cov kwj dej. Txawm li cas los xij, nws tsis yog txog rau xyoo 1960 uas lub hauv paus ntawm cov thev naus laus zis fiber niaj hnub tau tso. Xyoo 1966, tus kws tshawb fawb Askiv Charles K. Kao tau xav tias iav ntshiab tuaj yeem siv los xa cov teeb liab teeb mus deb nrog qhov poob teeb liab tsawg kawg nkaus.
Kev Sib Kis Fiber Optical Fiber Thawj Zaug
Xyoo 1970, thaum Corning Glass Works (tam sim no hu ua Corning Incorporated) tau ua tiav thawj lub fiber ntau optical uas tsis muaj kev poob qis siv cov iav ntshiab siab. Qhov kev tshawb pom no tau ua tiav qhov kev txo qis ntawm cov teeb liab tsawg dua 20 decibels ib mais (dB / km), ua rau kev sib txuas lus ntev yog qhov tseeb.
Qhov tshwm sim ntawm Ib Hom Fiber
Thoob plaws xyoo 1970, cov kws tshawb fawb tau txuas ntxiv txhim kho cov fibers optical, ua rau muaj kev tsim cov fiber ib hom. Hom fiber no tso cai rau kev poob qis dua thiab ua rau muaj kev xa cov ntaub ntawv ntau dua ntawm qhov deb ntev dua. Cov fiber ib hom sai sai no tau dhau los ua lub hauv paus ntawm kev sib txuas lus ntev.
Kev Lag Luam thiab Kev Sib Txuas Lus Boom
Xyoo 1980s tau cim lub sijhawm hloov pauv rau thev naus laus zis fiber ntau. Raws li kev nce qib hauv cov txheej txheem tsim khoom ua rau cov nqi qis dua, kev siv cov xov hlau fiber ntau hauv kev lag luam tau nce siab. Cov tuam txhab sib txuas lus tau pib hloov cov xov hlau tooj liab ib txwm muaj nrog cov xov hlau fiber ntau, ua rau muaj kev hloov pauv hauv kev sib txuas lus thoob ntiaj teb.
Lub Internet thiab Dhau Mus
Xyoo 1990, kev nce qib ntawm internet ua rau muaj kev xav tau ntau dua rau kev xa cov ntaub ntawv ceev ceev. Fiber optics tau ua lub luag haujlwm tseem ceeb hauv kev nthuav dav no, muab cov bandwidth tsim nyog los txhawb lub hnub nyoog digital. Thaum kev siv internet nce siab, qhov xav tau rau cov kev daws teeb meem fiber ntau dua kuj nce ntxiv.
Kev Nce Qib Hauv Wavelength Division Multiplexing (WDM)
Yuav kom tau raws li qhov kev thov bandwidth uas nce ntxiv tas li, cov engineers tau tsim Wavelength Division Multiplexing (WDM) thaum xyoo 1990. WDM thev naus laus zis tso cai rau ntau lub teeb liab ntawm ntau qhov wavelengths mus ncig tib lub sijhawm los ntawm ib qho fiber optical, ua rau nws muaj peev xwm thiab ua haujlwm tau zoo dua.
Kev Hloov Mus Rau Fiber Mus Rau Lub Tsev (FTTH)
Thaum peb nkag mus rau hauv lub xyoo pua tshiab, qhov kev tsom mus rau kev coj cov fiber optics ncaj qha mus rau cov tsev thiab cov lag luam. Fiber rau Lub Tsev (FTTH) tau dhau los ua tus qauv kub rau kev siv internet ceev ceev thiab cov kev pabcuam cov ntaub ntawv, ua rau muaj kev sib txuas tsis sib xws thiab hloov pauv txoj kev peb nyob thiab ua haujlwm.
Optical Fiber Niaj Hnub No: Kev Ceev, Peev Xwm, thiab Dhau Ntawm
Nyob rau xyoo tas los no, cov thev naus laus zis fiber ntau tau txuas ntxiv hloov zuj zus, thawb cov ciam teb ntawm kev xa cov ntaub ntawv. Nrog kev nce qib hauv cov ntaub ntawv fiber optic, cov txheej txheem tsim khoom, thiab cov txheej txheem sib txuas lus, peb tau pom qhov nce ntxiv ntawm cov ntaub ntawv ceev thiab peev xwm.
Yav Tom Ntej ntawm Kev Siv Tshuab Optical Fiber
Thaum peb saib mus rau yav tom ntej, lub peev xwm ntawm cov thev naus laus zis fiber ntau zoo li tsis muaj kev txwv. Cov kws tshawb fawb tab tom tshawb nrhiav cov ntaub ntawv tshiab, xws li cov fibers hollow-core thiab cov fibers photonic crystal, uas tuaj yeem txhim kho cov peev xwm xa cov ntaub ntawv ntxiv.
Xaus lus, thev naus laus zis fiber ntau tau los ntev txij li thaum nws pib. Txij li thaum pib ua lub tswv yim sim mus txog rau thaum ua lub hauv paus ntawm kev sib txuas lus niaj hnub no, thev naus laus zis zoo kawg no tau hloov pauv lub ntiaj teb. Ntawm OWCable, peb muaj kev txaus siab rau kev muab cov khoom siv fiber ntau tshiab thiab txhim khu kev qha tshaj plaws, tsav tsheb rau tiam tom ntej ntawm kev sib txuas thiab txhawb nqa lub hnub nyoog digital.
