Txuj ci Mainstream Fiber Optic zog ntsuas 'meter'
Fiber optic teeb qhov chaw yog ib qho ntawm cov fibre fiber optic test, siv los ntsuas cov fiber ntau qhov muag poob rau cov kab mob fiber ntau fiber ntau. Feem ntau cov hluav taws xob fiber optic teeb yog siv nrog qhov muag fais fab ntsuas .
Lub fiber ntau optic teeb ci feem ntau yog siv rau cov chaw uas muaj teeb meem uas tsis muaj qhov pom ntawm txoj kev pom mus rau sab nrauv. Qhov no ua rau lawv pab tau rau hauv cov ntawv xws li tshuaj. Qee cov tsev sib txuas nrog fibers optical li lub kav dej lossis lub teeb lub teeb, uas cov tshav ntuj teeb tau sau los ntawm sab nrauv ntawm lub tsev kom muaj teeb pom kev zoo rau qhov chaw nyob sab hauv. Ib lub teeb ci fiber-optic uas muaj fiber ntau ntawm fiber ntau uas tsim los kom txhob cia cov nqi ntau ntawm lub teeb kom xau los ntawm lawv txoj hlua thiab tawm ntawm cov fiber ntau los kuj siv dai kom zoo. Qhov no feem ntau muaj Christmas khoom plig thiab tuaj yeem siv rau hauv cov khoom xws li khw muag khoom, khaub ncaws, thiab teeb pom kev zoo.
Yeej muaj ob hom semiconductor lub teeb pom kev muaj rau kev sib txuas lus fiber ntau ntawm fiber ntau - Lub chaw thiab cov chaw laser.
Ib qho yooj yim LED lub teeb pom kev yog ib qho cim ntawm semiconductor nrog ap cheeb tsam thiab ib cheeb tsam n. Thaum cov LED qes dhau lawm, tam sim no ntws los ntawm LED. Raws li tam sim no ntws los ntawm cov LED, qhov hlws ris qhov twg p thiab n cov cheeb tsam ntsib emits random photons. Cov txheej txheem no yog hu ua kev tsis tuaj yeem tso tawm.
Ib yam li cov LED, lub laser yog ib qho hluav taws xob semiconductor nrog ap thiab n cheeb tsam. Tsis zoo li LED, lub laser muaj qhov kabmob kho qhov muag uas muaj cov tso tawm photons nrog reflecting tsom iav rau txhua qhov kawg ntawm lub diode. Ib qho ntawm cov reflection iav tsuas yog ib qho kev qhia. Daim iav no tso cai rau qee cov photons kom dim kev kho kab noj hniav.
Tab sis fiber ntau optic teeb pom tau hais tias yog hluav taws hau hluav taws xob nyob hauv chav ua hauj lwm. Qhov kev tshawb nrhiav no tau sim los txiav txim siab seb puas muaj cov thawv ntim huab cua sov (FAWB) uas yuav cuam tshuam txog kev tiv thaiv lossis kev sib kis ntawm cov hluav taws uas tshwm sim los ntawm cov teeb meem fiber ntau ntawm fiber optic. Kev tsim kho nyob rau hauv lub teeb ci thiab fiber optic technology tej zaum yuav ua rau cov hluav taws xob tso tawm ntawm pom thiab ntaiv cov infrared wavelengths kawg ntawm lub cable thiab nyob rau hauv lub ntsiab lus ntawm qhov endoscope. Tshaj siab tshaj tsis tsuas yog ua kom muaj kev pheej hmoo ntawm hluav taws, tab sis kuj tuaj yeem ua kom muaj kev pheej hmoo ntawm kub hnyiab thaum lub sijhawm ntsig txog cov ntaub so ntswg nrog lub tshuab raj. Vim tias lub cev siv hluav taws xob ntau ntawm qhov pom ntawm lub teeb ci wavelengths kuj tseem ua rau cov cua sov so, ntxiv cov khoom ntim ntawm infrared wavelengths yuav tsis tshem tawm qhov kev tsim txom no. Tsis tas li ntawd, nrog kev siv lub xov tooj hluav taws xob nrog cov koob yees duab video txuas nrog rau qhov kawg, ntau tus kws kho mob khiav lub teeb pom kev thaum lawv siab tshaj plaws thiab ntseeg tias lawv xav tau ntau dua cov kev siv lub teeb.
Tam sim no, Princeton Lightwave ntawm Cranbury, NJ thiab OFS Labs tau qhia txog fiber-optics-based solution. Cov teeb meem tshiab uas muaj fiber ntau tau muab coj los ua ke txhua qhov zoo tshaj plaws qhov tsim nyog rau qhov tseeb thiab ua haujlwm tau zoo tshaj plaws: lub teeb nrig, teeb meem loj heev dua ib cheeb tsam; ib tug nqaj hlau uas tsis muaj teeb meem uas tsis lam siv lub teeb pom kev los ntawm tsuas yog taws teeb lub duab; thiab "qhov chaw txias" uas tsis kub txog cov khoom siv. Tam sim no siv fiber ntau optic lub teeb xws li tungsten halogen yaj lossis cov arrays ntawm teeb-emitting diodes tsis muaj tsawg kawg yog ib qho ntawm cov qauv no.
Laser lub teeb siv los siv high-speed networking yog ib kab ntsig-kab zauv deg-emitter laser (VCSEL). Lub semiconductor diode combines high bandwidth nrog tsawg nqi thiab yog ib qho zoo tagnrho xaiv rau lub gigabit networking kev xaiv. Muaj kev xaiv ntau ntawm cov teeb nyob rau ntawm FOCC, uas muaj ob qho tib si handheld fiber ntau lub teeb ci qhov chaw thiab laser lub teeb qhov chaw , uas yuav tsum vov ntau yam ntawm cov kabmob uas muaj kabmob ua haujlwm kom haum txhua qhov kev sim tshuaj.
