Mzere wochedwa wa fiber optic kutengera switch yowala

Mfundo yaikulu ya mzere wochedwa wa Fiber optic

Mu kukonza ma signal a all-optical, ulusi wa kuwala ukhoza kuzindikira ntchito za kuchedwa kwa ma signal, kukulitsa, kusokoneza, ndi zina zotero. Kugwiritsa ntchito moyenera ntchitozi kungathandize kuzindikira kukonzedwa kwa chidziwitso m'munda wa all-optical. Pakati pawo, ntchito ya Delay ya optical Fiber ingapangidwe kukhala mzere wa delay wa Fiber optic, potengera ulusi wamba wa single-mode monga chitsanzo, pamene kutumiza kwa mafunde ogwirira ntchito a optical signal a 1550nm, kutumiza kwa mamita 200 kumatha kuchedwetsa 1μs, ndipo kutayika kwa insertion komwe kumatsatira ndi 0.04dB yokha. Poyerekeza, kutayika kwa insertion komwe kumachitika chifukwa cha mzere wachikhalidwe wa microwave delay ndi makumi angapo a dB, ndipo mzere wa delay wa optical fiber umachepetsa kutayika kwa insertion ndi pafupifupi ma orders awiri, zomwe zimapangitsa kuti mpikisano wa Fiber optic delay line ukhale wabwino kwambiri. Kuphatikiza apo, Ulusimzere wochedwetsa wa opticIlinso ndi mawonekedwe a kukula kochepa, kulemera kopepuka, bandwidth yayikulu yochedwa, mphamvu yamphamvu yotsutsana ndi maginito, ndipo imakhala mpikisano wamphamvu wa mizere yochedwa ya microwave, ndipo imatha kusintha kwathunthu mizere yochedwa ya microwave m'magawo ambiri. Poyerekeza ndi mzere wachikhalidwe wochedwa wa microwave, mzere wochedwa wa ulusi wa optical uli ndi bandwidth yayitali, zomwe zikusonyeza kuti dongosololi lili ndi resolution yabwino yoyezera pafupipafupi, kukhudzidwa kwambiri komanso kuthekera kwakukulu koletsa ma signal, ndipo imatha kukwaniritsa zofunikira za makina apamwamba a radar monga mizere yochedwa. Ndipo ma frequency operating a FDL ndi okwera kwambiri, amatha kukhala okwera kwambiri kuposa 100GHz, poyerekeza ndi mzere wochedwa wa pamwamba wa acoustic wave wa mazana a megahertz operating frequency ndi mzere wochedwa wa CCD wa makumi a megahertz operating frequency poyerekeza ndi ma order angapo, ndipo kutengera radar yolumikizirana yamtsogolo ndi machitidwe ena adzasintha kupita ku chizolowezi cha high frequency band, FDL ndi mwayi waukulu; Kuphatikiza apo, mzere wochedwa wa ulusi ulinso ndi mawonekedwe akuti kutayika kwa kuchedwa kwa unit sikudalira ma frequency. Ubwino wapadera wa mizere yochedwa ya fiber optic iyi mosakayikira umatsimikizira kuthekera kwake pakukonza ma signal.

Kugwiritsa ntchito chingwe chochedwa cha Fiber optic

Ntchito yaikulu ya mzere wa Fiber optic delay ndikuchedwetsa chizindikiro, chomwe chingagwire ntchito yosungira zonse ndi kusintha mofanana pogwiritsa ntchito kuchedwetsa, ndipo chili ndi ntchito zambiri mu radar ya phased array, system yolumikizirana ndi fiber optical, system ya makompyuta optical ndi njira zamagetsi zotsutsana. Mu radar ya phased array, antenna ya phased array ndiye gawo lalikulu, ntchito yayikulu ya antenna ya phased array ndikusintha ntchito ya kapangidwe ka beam yopangidwa, kuti ikwaniritse kusintha kwa mawonekedwe a beam ya antenna ndi kusanthula mwachangu kwa beam, ndipo ntchitoyi imachitika powongolera kuchuluka kwa amplitude ndi chidziwitso cha gawo la chizindikiro mu unit ya antenna, kotero mzere wochedwetsa ndi gawo lofunikira kwambiri. Poyerekeza ndi mzere wochedwetsa wa microwave, FDL ili ndi bandwidth yayikulu, ndipo palibe vuto la beam tilt. Mu antenna ya phased array yolamulidwa ndi optical, FDL imatha kuzindikira kugawa kwa gawo molondola ndikuwongolera chizindikiro cha microwave ndikuchotsa phokoso logwirizana ndi chizindikiro cha echo, kotero FDL ikhoza kukhala chisankho chabwino kwambiri mu antenna ya phased array. Mu radar target simulator, FDL imagwiritsidwa ntchito kutsanzira zizindikiro zakutali kosiyanasiyana. Ndi zofunikira za radar system yamakono ya radar target simulator, monga high frequency band, fast target switching speed ndi long target simulation, traditional delay line sakhala akukwaniritsa zofunikira za radar system, kotero fiber optic delay line yakhala yokhayo yomwe ingagwiritsidwe ntchito delay line. Kuphatikiza pa zomwe zili pamwambapa, mu optical fiber communication system, FDL imathanso kuzindikira ntchito ya signal coding ndi caching. Mwachidule, zitha kuwoneka kuti fiber optic delay line ili ndi ntchito zofunika komanso zosasinthika m'magawo ambiri, kotero kuphunzira kwa high-performance fiber optic delay line kuli ndi tanthauzo lalikulu la sayansi pakugwiritsa ntchitoukadaulo wa photon wa microwave.

Kapangidwe ka chingwe chochedwa cha Fiber optic

Mzere wochedwa wa fiber optic kutengera switch ya optical umasankha njira zosiyanasiyana za optical kuti ukwaniritse kuchedwa kwa nthawi kosiyanasiyana kudzera mu switch ya optical. Mfundo yayikulu ya mtundu uwu wa ndondomeko ndikukwaniritsa kuchedwa kosiyanasiyana mwa kusintha njira ya optical. Ndi mzere wamba wochedwa wa fiber optic, ndipo kapangidwe kake kabwino kakuwonetsedwa pachithunzichi.

 

Pambuyo poti chizindikiro cha kuwala chosinthidwa chatumizidwa kudzera mu ulusi wa kuwala, njira yowunikira yomwe imapanga kuchedwa kofanana imasankhidwa ndi gulu la optical switch, ndipo kuchedwa kofunikira kumatha kuchitika poyatsa optical switch ndikuwonetsetsa kuti ma switch ena a optical azimitsidwa. Ubwino wa mtundu uwu wa mzere wochedwa wa ulusi wa kuwala ndikuti ukhoza kuchedwa kwambiri, njira yodziwira ndi yosavuta, ndipo makhalidwe ofanana ndi osiyana malinga ndi kusankha ma switch osiyanasiyana a optical.
