Taw qhia rau Optical Fibers Thiab Cables

Ib qho fiber ntau optical yog dielectric waveguide uas xa cov teeb tsis muaj zog. Nws muaj ib tug filament muaj li ntawm ob concentric txheej ntawm pob tshab dielectric khoom. Cov khoom siv dielectric feem ntau yog quartz iav (SiO2). Lub sab hauv dielectric txheej yog hu ua "core," thiab nws cov refractive index yog siab dua li ntawm txheej dielectric txheej (lub npe hu ua "cladding"). Lub refractive indices ntawm cov tub ntxhais los yog cladding yog kho los ntawm doping lub quartz iav nrog impurities xws li germanium, phosphorus, fluorine, los yog boron. Optical fibers siv rau kev sib txuas lus feem ntau xa mus nyob ze -infrared lub teeb nyob rau hauv lub wavelength ntawm 0.8 mus rau 1.7 micrometers. Cov tub ntxhais txoj kab uas hla nws txawv nyob ntawm seb hom fiber ntau, feem ntau yog li ntawm ob peb micrometers mus txog 100 micrometers, thaum lub cheeb sab nraud feem ntau nyob ib ncig ntawm 125 micrometers. Lub fiber yog encased nyob rau hauv ib tug txheej yas txheej. Lub optical cable yog tsim los ntawm bundling ib los yog ntau dua optical fibers ua ke, nrog rau kev txhawb zog thiab tiv thaiv cov ntsiab lus. Cov kab hluav taws xob kho qhov muag tuaj yeem siv tau thiab siv nyob rau hauv ntau qhov chaw. Cov txheej txheem tsim khoom rau optical cables zoo ib yam li cov hluav taws xob cables.

Optical Fibers thiab Cables

Kev sib txuas lus kho qhov muag fiber ntau yog ib txoj hauv kev tseem ceeb tshaj plaws ntawm kev xa xov xwm niaj hnub no. Nws muaj ntau yam zoo, nrog rau kev muaj peev xwm sib kis tau ntev, kev sib txuas ntev ntev, txhim khu kev ruaj ntseg, tiv thaiv kev cuam tshuam ntawm electromagnetic, thiab kev txuag ntawm tooj liab.

Raws li cov ntaub ntawv kev lag luam uas tau sau los ntawm ntev - lub sij hawm taug qab ntawm kev lag luam fiber ntau thiab cable, daim ntawv tshaj tawm no tsim cov txheej txheem kev tshuaj xyuas uas tshuaj xyuas cov haujlwm los ntawm kev nthuav dav, kev lag luam- kev pom dav. Daim ntawv tshaj tawm feem ntau txheeb xyuas lub xeev tam sim no ntawm kev txhim kho thiab kev cia siab rau yav tom ntej ntawm Tuam Tshoj txoj kev lag luam fiber ntau thiab cable, kev lag luam kev sib tw toj roob hauv pes thiab kev lag luam concentration, thiab cov txheej txheem thev naus laus zis tam sim no ntawm cov sector.
