Qee lub sij hawm dhau los hauv Cellulose magazine muaj Kev tshawb fawb los ntawm Finnish cov kws tshawb fawb uas tau tham txog kev tsim cov fiber ntau optical los ntawm cellulose. Lub tswv yim los tsim cov teeb pom kev zoo fiber ntau thawj zaug tau tsim nyob rau xyoo 1910. Ntau xyoo dhau los, fiber ntau optic cables tau dhau los ua qhov tseeb txhua hnub thiab ib qho tseem ceeb ntawm kev siv hluav taws xob sib kis ntawm cov ntaub ntawv tshaj kaum tawm txhiab mais.
Lub cellulose optical fiber tsim los ntawm Finnish cov kws tshawb fawb tsis haum rau kev sib txuas lus. Lub teeb attenuation nyob rau hauv nws yog siab dhau - mus txog 6,3 dB ib centimeter nyob rau hauv qhib huab cua rau ib tug wavelength ntawm 1300 nm. Hauv dej, qhov attenuation tau nce mus rau 30 dB ib centimeter. Tab sis cov cuab yeej no tau dhau los ua qhov xav tau tshaj plaws. Xws li cellulose optical fibers, vim lawv lub peev xwm los ntub dej, yuav ua pov thawj tias yog ib qho tseem ceeb thiab yooj yim rau kev ntsuas av noo.
Lub ntiaj teb ntawm cov ntse sensors thiab cov khoom sib txuas hauv Is Taws Nem tuaj yeem pom cov hloov pauv tau yooj yim, ntev-ntev, yooj yim, thiab lub zog txuag cov av noo. Cov kev daws teeb meem zoo li no tuaj yeem ua rau hauv lub hauv paus ntawm cov tsev thiab cov qauv los tswj cov dej noo hauv cov qauv monolithic, piv txwv li, tswj cov qib dej nyab thiab dej hauv av. Cov khoom siv hluav taws xob hnav tau tuaj yeem ntxiv nrog lub cev thiab cov khaub ncaws noo noo sensors, uas yog qhov tseem ceeb hauv lub neej txhua hnub rau kev saib xyuas cov menyuam yaus thiab cov neeg nyiam sab nraum zoov.
Optical fibers ua los ntawm cov ntaub ntawv yas twb tau mastered lub niche ntawm sensors rau sau seismic cov ntaub ntawv, xws li txawm thiab tshwj xeeb tshaj yog nrov nrov ntawm txoj kev hauv nroog (suav phom, suab ntawm kev sib tsoo, thiab lwm yam). Nrog rau qhov tshwm sim ntawm cellulose optical fibers, kev siv cov hloov tau yooj yim, thermally ruaj khov thiab ruaj khov kho qhov muag cables yuav nthuav dav rau kev saib xyuas cov av noo, ib yam dab tsi uas cov yas kho qhov muag fibers tsis muaj peev xwm ntawm txoj cai.
