Fiber optic qeeb kab raws li optical switch

Lub hauv paus ntsiab lus ntawm Fiber optic qeeb kab

Hauv kev ua cov teeb liab tag nrho, cov fiber ntau tuaj yeem ua tiav cov haujlwm ntawm kev ncua sijhawm teeb liab, kev nthuav dav, kev cuam tshuam, thiab lwm yam. Kev siv cov haujlwm no kom raug tuaj yeem ua tiav cov ntaub ntawv ua tiav hauv txhua qhov chaw teeb liab. Ntawm lawv, qhov kev ncua sijhawm ntawm cov fiber ntau tuaj yeem ua rau hauv cov kab qeeb qeeb fiber ntau, coj cov fiber ntau ib hom ua piv txwv, thaum xa cov teeb liab ua haujlwm wavelength ntawm 1550nm, xa ntawm 200 meters tuaj yeem ua tiav qhov qeeb ntawm 1μs, thiab qhov poob ntawm kev ntxig nrog tsuas yog 0.04dB. Piv txwv li, qhov poob ntawm kev ntxig los ntawm cov kab qeeb qeeb microwave ib txwm muaj yog kaum ob ntawm dB, thiab cov kab qeeb qeeb fiber ntau txo qhov poob ntawm kev ntxig los ntawm ze li ntawm 2 qhov kev txiav txim ntawm qhov loj, uas ua rau kev sib tw ntawm cov kab qeeb qeeb fiber ntau zoo dua. Tsis tas li ntawd, Fiberkab qeeb qeeb ntawm qhov muagkuj muaj cov yam ntxwv ntawm qhov me me, lub teeb yuag, cov khoom lag luam qeeb bandwidth loj, muaj peev xwm tiv thaiv kev cuam tshuam electromagnetic, thiab dhau los ua tus neeg sib tw muaj zog ntawm cov kab microwave qeeb, thiab tuaj yeem hloov pauv cov kab microwave qeeb hauv ntau qhov chaw. Piv nrog rau cov kab microwave qeeb ib txwm muaj, cov kab fiber ntau optical qeeb muaj cov khoom lag luam bandwidth siab, uas qhia tau tias lub kaw lus muaj qhov kev daws teeb meem zoo ntawm kev ntsuas zaus, kev rhiab heev thiab kev cuam tshuam teeb liab siab, thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov kab radar siab xws li cov kab qeeb. Thiab FDL kev ua haujlwm zaus siab heev, tuaj yeem siab dua 100GHz, piv nrog cov kab acoustic nthwv dej ntawm ntau pua megahertz kev ua haujlwm zaus thiab CCD qeeb kab ntawm kaum megahertz kev ua haujlwm zaus piv nrog ntau qhov kev txiav txim ntawm qhov loj me, thiab raws li kev sib txuas lus radar yav tom ntej thiab lwm lub kaw lus yuav hloov mus rau qhov sib txawv ntawm cov zaus zaus siab, FDL yog qhov zoo tseem ceeb; Tsis tas li ntawd, cov kab qeeb fiber kuj muaj tus yam ntxwv uas qhov poob ntawm chav tsev qeeb tsis yog ywj pheej ntawm zaus. Cov txiaj ntsig tshwj xeeb ntawm cov kab fiber optic qeeb no tsis ntseeg ua pov thawj nws lub peev xwm hauv kev ua cov teeb liab.

Daim ntawv thov ntawm Fiber optic qeeb kab

Lub luag haujlwm tseem ceeb ntawm Fiber optic qeeb kab yog ncua lub teeb liab, uas tuaj yeem ua tiav lub luag haujlwm ntawm txhua qhov kev cia khoom thiab hloov pauv sib npaug los ntawm kev siv qeeb, thiab muaj ntau yam kev siv hauv phased array radar, optical fiber sib txuas lus system, optical computer system thiab electronic countermeasures. Hauv phased array radar, phased array antenna yog lub hauv paus tseem ceeb, lub luag haujlwm tseem ceeb ntawm phased array antenna yog hloov cov qauv ua haujlwm ntawm cov synthesized beam, kom ua tiav qhov kev hloov pauv ntawm lub antenna beam duab thiab kev luam theej sai ntawm lub beam, thiab lub luag haujlwm no yog ua tiav los ntawm kev tswj hwm qhov amplitude thiab theem cov ntaub ntawv ntawm lub teeb liab hauv lub antenna unit, yog li ntawd lub qeeb kab yog ib feem tseem ceeb. Piv nrog microwave qeeb kab, FDL muaj bandwidth loj dua, thiab tsis muaj teeb meem ntawm beam tilt. Hauv optically tswj phased array antenna, FDL tuaj yeem ua tiav qhov tseeb theem faib thiab tswj hwm ntawm microwave teeb liab thiab tshem tawm cov suab nrov ntawm echo teeb liab, yog li FDL tuaj yeem yog qhov kev xaiv zoo tshaj plaws hauv phased array antenna. Hauv radar target simulator, FDL yog siv los simulate cov teeb liab ntawm ntau qhov deb. Nrog rau qhov yuav tsum tau ua ntawm lub tshuab radar niaj hnub rau radar lub hom phiaj simulator, xws li cov zaus siab, lub hom phiaj hloov ceev thiab lub hom phiaj simulation ntev, cov kab qeeb ib txwm tsis tau ua raws li qhov yuav tsum tau ua ntawm radar system, yog li fiber optic qeeb kab tau dhau los ua tib txoj kab qeeb siv tau. Ntxiv rau qhov saum toj no, hauv lub tshuab sib txuas lus fiber ntau, FDL kuj tuaj yeem paub txog kev ua haujlwm ntawm cov cim coding thiab caching. Hauv kev xaus, nws tuaj yeem pom tias fiber optic qeeb kab muaj cov ntawv thov tseem ceeb thiab tsis tuaj yeem hloov pauv tau hauv ntau qhov chaw, yog li kev kawm txog kev ua haujlwm siab fiber optic qeeb kab muaj qhov tseem ceeb ntawm kev tshawb fawb rau daim ntawv thov ntawmkev siv tshuab microwave photon.

Kev tsim ntawm Fiber optic qeeb kab

Cov kab fiber optic qeeb raws li qhov hloov kho qhov muag xaiv cov kev kho qhov muag sib txawv kom ua tiav cov sijhawm qeeb sib txawv los ntawm qhov hloov kho qhov muag. Lub hauv paus ntsiab lus ntawm hom phiaj xwm no yog kom ua tiav cov sijhawm qeeb sib txawv los ntawm kev hloov txoj kev kho qhov muag. Nws yog ib qho kab fiber optic qeeb sib cais, thiab nws cov qauv ib txwm muaj nyob hauv daim duab.

 

Tom qab lub teeb liab optical modulated raug xa mus los ntawm cov fiber ntau optical, txoj kev optical uas tsim cov kev ncua sij hawm sib xws yog xaiv los ntawm cov khoom siv hloov optical, thiab qhov kev ncua sij hawm xav tau tuaj yeem ua tiav los ntawm kev tig rau ntawm qhov hloov optical thiab xyuas kom meej tias lwm cov khoom siv hloov optical raug kaw. Qhov zoo ntawm hom kab qeeb optical fiber no yog tias nws tuaj yeem ua tiav qhov kev ncua sij hawm loj, txoj kev paub tseeb yog yooj yim, thiab cov yam ntxwv sib xws yog txawv raws li kev xaiv ntawm cov khoom siv hloov optical sib txawv.
