Nyob zoo, Muaj nuj nqis nyeem thiab thev naus laus zis! Niaj hnub no, peb tau txais txoj kev taug kev ntxim nyiam rau hauv keeb kwm thiab cov cim tshiab ntawm cov tshuaj muaj fiber ntau thev naus laus zis. Raws li ib qho ntawm cov kws muab kev pab ua kom txiav cov khoom siv roj fiber ntau yam khoom siv hluav taws xob, OwCable tau nyob ntawm qhov ua ntej ntawm qhov kev lag luam zoo tshaj plaws. Cia peb ntsaub mus rau hauv kev hloov pauv ntawm kev siv thev naus laus zis no thiab nws cov txiaj ntsig tseem ceeb.
Yug ntawm fiber ntau
Lub tswv yim ntawm kev coj lub teeb los ntawm cov hnub sib xyaw pob tshab nruab nrab rov qab mus rau lub xyoo pua puv 19, nrog cov kev sim thaum ntxov muaj nrog cov pas nrig thiab dej raws. Txawm li cas los xij, nws tsis yog txog lub 1960 uas lub hauv paus ntawm niaj hnub kho fiber ntau thev naus laus zis tau nteg. Xyoo 1966, British Diam Physicist Charles K. Kao theorized tias ntshiab iav yuav siv tau los xa cov cim teeb hla dhau nrog qhov kev ncua ntev ntawm kev ncua ntev.
Thawj Optical Fiber Cuam Tshuam
Sai rau pem hauv ntej rau xyoo 1970, thaum Corning iav ua haujlwm (Tam sim no Corning Corned Computers) ua tiav optical fiber siv high-purity iav. Qhov kev sib tsoo no tau ua tiav cov paib kev ua haujlwm tsawg dua 20 decibels ib km kilometer (DB / KM), ua kev sib txuas lus ntev ntev.
Qhov tshwm sim ntawm ib-hom fiber ntau
Thoob plaws xyoo 1970, cov kws tshawb nrhiav txuas ntxiv txhawm rau txhim kho cov khoom siv kho kho qhov muag, ua rau kev loj hlob ntawm ib hom fiber ntau. Hom fiber ntau no tso cai rau txawm tias qis teeb liab poob thiab qhib cov ntaub ntawv ntau dua kis tau deb dua. Ib leeg-hom fiber sai sai dhau los ua tus caj qaum ntawm kev sib txuas lus ntev ntev.
Kev Ua Lag Luam thiab Kev Sib Tw Sib Tham
Lub 1980s khij ib qho tig taw rau kev siv kho lub fiber ntau thev naus laus zis. Raws li nce qib hauv kev tsim cov txheej txheem tsim qauv tau ua rau cov nqi, kev ua lag luam saws me nyuam fiber ntau ectomic cables. Cov tuam txhab sib txuas xov tooj pib hloov tooj liab liab tsheb tooj nrog cov khoom siv kho kom zoo nkauj, ua rau kev hloov pauv hauv ntiaj teb.
Is Taws Nem thiab dhau mus
Nyob rau xyoo 1990, sawv ntawm Is Taws Nem raug tshem tawm qhov tsis tau xav tau rau cov ntaub ntawv xa nrawm. Fiber Optics ua si lub luag haujlwm tseem ceeb hauv qhov kev nthuav dav no, muab cov bandwidth tsim nyog los txhawb lub hnub nyoog digital. Raws li Internet siv skyrocketed, yog li ua qhov xav tau rau kev txhim kho kho tshiab fiber ntau.
Kev nce qib hauv wavelength division multiplexing (WDM)
Txhawm rau kom tau raws li qhov kev xav tau ib txwm muaj rau bandwidth, engineers tsim wavelength faib multiplexing (WDM) thaum xyoo 1990. WDM thev naus laus zis tso cai ntau cov cim ntawm cov wavelengths sib txawv los mus ncig ua ke los ntawm ib lub khoos kas kho qhov muag ib zaug, nthuav dav nws lub peev xwm thiab kev ua tau zoo.
Kev hloov mus rau fiber ntau rau lub tsev (FTH)
Raws li peb tau nkag mus rau lub xyoo txhiab tshiab, lub ntsiab ua ke txav ntawm kev nqa cov fiber ntau optics ncaj qha rau tsev thiab kev lag luam. Fiber rau hauv lub tsev (FTH) tau los ua tus qauv kub rau kev siv internet ceev thiab cov ntaub ntawv kev sib txuas, hloov txoj kev uas peb nyob thiab ua haujlwm.
Niaj hnub no cov fiber ntau hnub no: ceev, muaj peev xwm, thiab dhau ntawd
Nyob rau hauv xyoo tas los, kho qhov siv thev naus laus zis tau txuas ntxiv hloov zuj zus, thawb cov ciam ntawm cov ntaub ntawv kis. Nrog kev nce qib hauv cov ntaub ntawv fiber ntau, tsim kev lag luam, thiab kev sib koom tes ua raws li kev nthuav dav hauv cov ntaub ntawv ceev thiab muaj peev xwm.
Lub neej yav tom ntej ntawm optical fiber ntau thev naus laus zis
Raws li peb saib rau yav tom ntej, lub peev xwm ntawm kev siv tshuaj tivthaical fiber ntau yam tsis muaj kev txwv. Cov kws tshawb nrhiav tau tshawb txog cov ntaub ntawv tshiab, xws li hollow-core crystal fibers, uas tuaj yeem txhim kho cov ntaub ntawv kis tau.
Hauv kev xaus, khoos phis tawm kho mob tau tuaj ntev dua txij li thaum nws pib. Los ntawm nws cov kev txo hwj chim pib ua kev sim los ua tus caj qaum ntawm kev sib txuas lus niaj hnub no, cov cuab yeej tsis zoo no tau hloov kho lub ntiaj teb. Ntawm plose, peb zoo siab rau muab cov khoom siv fiber ntau thiab feem ntau txhim kho cov khoom siv fiber ntau cov khoom siv, tsav tsheb rau cov khoom sib txuas ntxiv thiab txhawb nqa lub hnub nyoog digital.
