Fiber Optic Chronicles

1880 Alexandra Graham Tswb tau tsim kev sib txuas lus kab sib txuas
1960 Invention of Radio thiab Fiber Optics
Kev sib kis ntawm 1960 iav fiber ntau yog ntau dua 1000dB / km, thaum lwm cov ntaub ntawv muaj xws li aperture waveguides, gas lens waveguides, hollow hlau waveguides, thiab lwm yam.
Thaum Lub Xya Hli 1966, Dr. KC Kao, tus kws tshawb fawb Askiv thiab Suav, tau luam tawm ib daim ntawv hauv PIEE phau ntawv xov xwm hu ua "Dielectric Fiber Surface Waveguides for Optical Frequencies", uas tau soj ntsuam thiab ua pov thawj qhov muaj peev xwm ntawm kev siv cov fibers optical los ua cov xov xwm xa mus rau kev kho qhov muag. kev sib txuas lus, thiab kwv yees qhov ua tau ntawm kev tsim ultra-tsawg poob optical fibers rau kev sib txuas lus
Xyoo 1970, peb tus kws tshawb fawb los ntawm Corning Corporation hauv Tebchaws Meskas, Mariel, Kaplon, thiab Keck, tau ua tiav qhov kev poob qis quartz fiber ntau nrog kev sib kis ntawm tsuas yog 20dB / km siv txoj kev txhim kho chemical theem deposition (MCVD txoj kev).
Xyoo 1970, Tswb Laboratories hauv Tebchaws Meskas tau tsim lub ntiaj teb thawj gallium arsenide semiconductor laser uas ua haujlwm tsis tu ncua ntawm chav tsev kub.
1972 Kev sib kis poob qis rau 4dB / km
Xyoo 1974, Lub Tsev Haujlwm Tswb ntawm Tebchaws Meskas tau tsim txoj kev tsim cov fiber ntau uas tsis tshua muaj - CVD (cov tshuaj vapor deposition method), uas txo cov fiber ntau xa mus rau 1.1 dB / km.
Xyoo 1976, Tebchaws Meskas tau qhib lub ntiaj teb thawj qhov kev sim kab rau kev sib txuas lus fiber ntau los ntawm cov kav dej hauv av ntawm Bell Laboratories hauv Atlanta. A 144 fiber optic cable yog siv los xa cov teeb liab ntawm tus nqi ntawm 44.736Mbps, nrog rau qhov kev ncua deb ntawm 10 km. Peb siv multimode optical fibers, thiab lub teeb ci yog lub teeb-emitting diode LED nrog lub wavelength ntawm 0.85 microns ntawm lub teeb infrared.
1976 Kev sib kis poob qis rau 0.5dB/km
Xyoo 1977, Tswb Tshawb Fawb Lub Tuam Txhab thiab Nippon Telegraph thiab Xov Tooj Tuam Txhab yuav luag ib txhij tsim lub tshuab hluav taws xob semiconductor nrog lub neej ntev ntawm 1 lab teev (kwv yees li 10 xyoo hauv kev siv tswv yim)
Xyoo 1977, lub ntiaj teb thawj fiber optic kev sib txuas lus tau muab tso rau hauv kev lag luam siv hauv Chicago, Tebchaws Asmeskas, nrog kev ceev ntawm 45Mb / s.
Xyoo 1977 Thawj qhov kev teeb tsa ntawm xov tooj fiber ntau optic network
1978 FORT thawj txhim kho nws cov khoom siv fiber ntau hauv Fabkis
Xyoo 1979, Zhao Zisen tau tsim thawj cov khoom siv kho qhov muag kho qhov muag ntawm nws tus kheej tsim hauv Suav teb, hu ua "leej txiv ntawm Suav optical fibers"
1979 Kev sib kis poob qis rau 0.2dB/km
Kev lag luam ntawm 1980 multimode fiber optic kev sib txuas lus system (140Mb / s) thiab pib ntawm qhov chaw sim ntawm ib hom fiber ntau optic kev sib txuas lus
Xyoo 1990, ib hom fiber ntau optic kev sib txuas lus tau nkag mus rau theem kev lag luam (565Mb / s) thiab pib qhov chaw sim ntawm xoom dispersion hloov fiber ntau, wavelength division multiplexing, thiab kev sib txuas lus. Tsis tas li ntawd, cov qauv txheej txheem rau Digital Synchronous Hierarchy (SDH) tau maj mam tsim
Hauv 1990, kev sib kis poob qis rau 0.14dB/km, mus txog qhov kev txwv theoretical attenuation ntawm 0.1dB/km rau quartz optical fibers
Fiber Optics rau 1990 Regional Networks thiab lwm yam luv luv kev sib kis daim ntawv thov
Xyoo 1992, Tswb Laboratories thiab cov neeg koom tes Nyij Pooj tau ua tiav qhov ntsuas qhov muag pom tau tias tuaj yeem xa 9000 mais yam tsis muaj qhov yuam kev, nrog tus nqi pib ntawm 5Gbps thiab tom qab ntawd nce mus rau 10Gbps.
1993 SDH cov khoom pib ua lag luam (hauv qab 622Mb / s)
1995 2.5Gb/s SDH cov khoom tau nkag mus rau theem kev lag luam
1996 10Gb/s SDH cov khoom tau nkag mus rau theem kev lag luam
Qhov tseem ceeb tshaj plaws tau ua nyob rau hauv kev sim ntawm 20Gb / s thiab 40Gb / s SDH cov khoom siv Wavelength Division Multiplexing (WDM) technology hauv 1997
2000 to roofside fiber optic=>mus rau tableside fiber optic
2005 3.2Tbps Ultra Loj Muaj Peev Xwm Fiber Optic Kev Sib Txuas Lus Qhib los ntawm Shanghai mus rau Hangzhou
2005 FTTH (Fiber Rau Lub Tsev) Fiber ncaj nraim rau tsev
Lub 2021 Distributed Fiber Optic Sensing Technology Application Exhibition tau muaj nyob rau hauv Beijing. Fiber optics tsis yog tsuas yog "cov hlab ntsha" uas xa cov teeb liab, tab sis kuj yog "cov hlab ntsha" uas saib xyuas cov teeb liab hnub no.
