Vim li cas Fiber Optic Cables siv nyob rau hauv kev sib txuas lus Ntau thiab Ntau
Qhov kev txhim kho tshiab hauv kev sib txuas lus yog coj los rau peb ntawm cov khoom siv hluav taws xob siv hluav taws xob. Lawv pab xa cov ntawv xov xwm mus rau ntau qhov chaw uas tsis tas yuav poob. Lawv yog cov ntau dua thiab zoo dua li txhua yam kev sib txuas wireless thaum lawv ua haujlwm ntawm lawv qib siab tshaj plaws. Tsis zoo li cov kev sib txuas sib txuas lus, fiber optics tsis pom muaj teeb liab.
Tab sis dab tsi yog qhov muag fibers? Cov no yog cov iav los ntawm cov iav los yog cov yas uas muaj nyob rau hauv ib lub thawv los ntawm cov khoom uas tsis tshua muaj neeg sab nrauv. Nrog kev pab ntawm reflections, nws muaj peev xwm ntawm kis lub teeb thoob plaws hauv nws ntev ces cov Pib ntsais koj teeb yog kis tau raws li ib tug txhais tau tias ntawm kev sib txuas lus. Qhov no ua rau txoj kev sib txuas lus siv fiber ntau uas ua rau hloov suab, cov ntaub ntawv thiab cov duab tau. Nws muaj ob peb nta uas ua kom yooj yim rau siv.
Vim li cas fiber optic cables siv sib txuas lus ntau dua ? Vim tias muaj ntau qhov zoo ntawm cov kab mob fiber ntau hauv kev sib txuas lus raws li nram qab no.
Muab ntau dua kev kis bandwidth piv rau qhov qub kev sib txuas cable system. Nws muaj ib qho kev muaj peev xwm loj heev nrog kev muaj zog nyob hauv qhov ntau ntawm 1013 txog 1016 Hz.
Lawv sib zog thiab deb tsawg dua tooj liab kab hlau vim nws txoj kab uas muaj zog tsawg. Fiber optics yog tube-zoo li qauv tsis muaj ntau tshaj li ib tug tib neeg cov plaub hau.
Optical fiber cable yog hluav taws xob insulators yog li lawv tsis tso lub ntiaj teb loop thiab interface teeb meem. Tus cwj pwm no yog ib qho zoo dua vim tias nws siv tau txawm nyob hauv ib qhov chaw muaj kev tiv thaiv hluav taws xob.
Txoj kev kis tau yooj yim thiab tsis cuam tshuam rau qhov lawv tsim ib lub dielectric waveguide uas tiv thaiv electromagnetic thiab xov tooj cua zaus cuam. Kev xa tawm ntawm cov paib tsis muaj qhov cuam tshuam los ntawm qhov chaw muaj pa hluav taws.
Lawv muaj teeb meem kev ruaj ntseg.
Cov txuj ci tseem niaj hnub zoo tshaj plaws thiab cov kev daws teeb meem tsis sib kis tau yooj yim piv rau tooj liab xov hlau.
Raws li kev siv technology, kho qhov muag fibers ua ntau thiab ntau saj thiab rugged. Optical fiber cables yog yooj yim cia, thauj, kov thiab nruab sib piv rau tooj liab xov hlau.
Optical fibers yog ib qho yooj yim los tswj thiab vim tsis tau khoom ntawm cov khoom, lawv qhov kev ntseeg tau zoo dua yog piv rau cov khoom siv hluav taws xob hluav taws xob.
Koj tsis tas yuav txhawj txog cov nuj nqis uas muaj peev xwm ua rau hauv chav kawm uas siv rau hauv kev txiav txim siab ntawm cov fibers yog tsim los ntawm cov xuab zeb, cov ntaub ntawv ntau heev.
Cov no yog cov qee cov txiaj ntsim ntawm fiber ntau optics daws lossis cov hauv kev sib txuas lus hauv kev sib txuas lus. Raws li lub tshuab evolves, yog li ntawm txoj kev sib txuas lus. Kev siv cov fibers optical ua ntau dua rampant ntau thiab ntau tus neeg relies on nws stability thiab muaj peev xwm xa cov ntaub ntawv tseem ceeb tsis poob.
FOCC yog cov khoom siv fiber ntau fiber ntau uas yog cov khoom siv fiber ntau tshaj plaws ntawm cov khoom siv fiber ntau. Muaj tag nrho cov hom fiber ntau optic rau kev muag khoom. Tsis tsuas yog iav fiber ntau cab, tab sis kuj muab cov yas fiberglass fibers.
