Umugqa wokulibaziseka we-fiber optic osuselwe kuswishi yokukhanya

Isimiso somugqa wokulibaziseka we-Fiber optic

Ekucutshungulweni kwesignali ye-all-optical, i-optical fiber ingaqaphela imisebenzi yokubambezeleka kwesignali, ukunwebeka, ukuphazamiseka, njll. Ukusetshenziswa okunengqondo kwale misebenzi kungaqaphela ukucutshungulwa kolwazi ensimini ye-all-optical. Phakathi kwazo, umsebenzi we-Delay we-optical Fiber ungenziwa ube umugqa wokulibaziseka we-Fiber optic, kuthathwa i-optical fiber evamile yemodi eyodwa njengesibonelo, lapho ukudluliswa kobude besikhathi sokusebenza kwesignali ye-optical engu-1550nm, ukudluliswa kwamamitha angu-200 kungafinyelela ukubambezeleka okungu-1μs, kanti ukulahlekelwa kokufakwa okuhambisanayo kungu-0.04dB kuphela. Uma kuqhathaniswa, ukulahlekelwa kokufakwa okubangelwa umugqa wokulibaziseka we-microwave wendabuko kungama-dB amaningi, kanti umugqa wokulibaziseka we-optical fiber unciphisa ukulahlekelwa kokufakwa cishe ngama-oda amabili ngobukhulu, okuthuthukisa kakhulu ukuncintisana komugqa wokulibaziseka we-Fiber optic. Ngaphezu kwalokho, i-Fiberumugqa wokulibaziseka we-opticfuthi zinezici zobukhulu obuncane, isisindo esilula, umkhiqizo we-bandwidth yokubambezeleka okukhulu, ikhono eliqinile lokuphazamiseka kwe-anti-electromagnetic, futhi zibe umncintiswano oqinile wemigqa yokubambezeleka kwe-microwave, futhi zingashintsha ngokuphelele imigqa yokubambezeleka kwe-microwave emikhakheni eminingi. Uma kuqhathaniswa nomugqa wendabuko wokubambezeleka kwe-microwave, umugqa wokubambezeleka kwe-fiber optical unomkhiqizo we-bandwidth yesikhathi esiphezulu, okubonisa ukuthi uhlelo lunesisombululo esihle sokulinganisa imvamisa, ukuzwela okuphezulu kanye nekhono lokuvimba isignali ephezulu, futhi lungahlangabezana nezidingo zezinhlelo ze-radar ezinesinqumo esiphezulu njengemigqa yokubambezeleka. Futhi imvamisa yokusebenza ye-FDL iphakeme kakhulu, ingaba phezulu kakhulu kune-100GHz, uma kuqhathaniswa nomugqa wokubambezeleka kwegagasi le-acoustic wave wamakhulu emvamisa yokusebenza ye-megahertz kanye nomugqa wokubambezeleka we-CCD wamashumi emvamisa yokusebenza ye-megahertz uma kuqhathaniswa nama-oda amaningana amakhulu, futhi ngokusekelwe ku-radar yokuxhumana yesikhathi esizayo kanye nezinye izinhlelo zizoshintshela ekuthambekeleni kwebhendi yemvamisa ephezulu, i-FDL iyinzuzo ebalulekile; Ngaphezu kwalokho, umugqa wokubambezeleka kwe-fiber uphinde ube nesici sokuthi ukulahlekelwa kokubambezeleka kweyunithi akuxhomekile emvamisa. Izinzuzo ezihlukile zale migqa yokubambezeleka kwe-fiber optic ngokungangabazeki zifakazela amandla ayo ekucutshungulweni kwesignali.

Ukusetshenziswa komugqa wokulibaziseka we-Fiber optic

Umsebenzi oyisisekelo womugqa wokulibaziseka we-Fiber optic ukulibaziseka kwesignali, okungafeza umsebenzi wokugcina wonke ama-optical kanye nokulingana kokushintsha ngokusebenzisa ukulibaziseka, futhi kunezinhlelo zokusebenza eziningi ku-radar ye-phased array, uhlelo lokuxhumana lwe-optical fiber, uhlelo lwekhompyutha lwe-optical kanye nezindlela zokulinganisa ze-elekthronikhi. Ku-radar ye-phased array, i-antenna ye-phased array iyisici esiyinhloko, umsebenzi oyinhloko we-antenna ye-phased array ukushintsha umsebenzi wephethini womsebe owenziwe, ukuze kufezwe ushintsho lwesimo somsebe we-antenna kanye nokuskena okusheshayo komsebe, futhi lo msebenzi ufezwa ngokulawula ulwazi lwe-amplitude kanye nesigaba sesiginali kuyunithi ye-antenna, ngakho-ke umugqa wokulibaziseka uyingxenye ebalulekile. Uma kuqhathaniswa nomugqa wokulibaziseka we-microwave, i-FDL ine-bandwidth enkulu, futhi akukho nkinga yokuthambekela komsebe. Ku-antenna ye-phased array elawulwa ngokukhanya, i-FDL ingafeza ukwabiwa kwesigaba okunembile kanye nokulawula isiginali ye-microwave futhi isuse umsindo ohambisanayo wesiginali ye-echo, ngakho-ke i-FDL ingaba yisinqumo esihle kakhulu ku-antenna ye-phased array. Ku-simulator ye-radar target, i-FDL isetshenziselwa ukulingisa izimpawu zamabanga ahlukene. Ngezidingo zesistimu yesimanje ye-radar ye-radar target simulator, njenge-band yemvamisa ephezulu, isivinini sokushintsha okuqondiwe okusheshayo kanye nebanga elide lokulingisa okuqondiwe, imigqa yokulibaziseka yendabuko ibilokhu ikude kakhulu nokuhlangabezana nezidingo zesistimu ye-radar, ngakho-ke i-fiber optic delay line ibe yiyo kuphela i-delay line esebenzayo. Ngaphezu kwalokhu okungenhla, ohlelweni lokuxhumana lwe-optical fiber, i-FDL ingaphinde ifeze umsebenzi wokubhala ikhodi yesiginali kanye nokugcina isikhashana. Ngamafuphi, kungabonakala ukuthi i-fiber optic delay line inezinhlelo zokusebenza ezibalulekile kanye nesimo esingenakufakwa esikhundleni emikhakheni eminingi, ngakho-ke ucwaningo lwe-high-performance fiber optic delay line lubaluleke kakhulu kwesayensi ekusetshenzisweni kwe-ubuchwepheshe be-photon ye-microwave.

Umklamo womugqa wokulibaziseka we-Fiber optic

Umugqa wokulibaziseka we-fiber optic osuselwe kuswishi yokukhanya ukhetha izindlela ezahlukene zokukhanya ukuze kufezwe ukubambezeleka kwesikhathi okuhlukile ngeswishi yokukhanya. Isimiso esiyisisekelo salolu hlobo lwesikimu ukufeza ukubambezeleka okuhlukile ngokushintsha indlela yokukhanya. Ungumugqa wokulibaziseka we-Fiber optic ojwayelekile ohlukile, futhi isakhiwo sawo esijwayelekile siboniswe esithombeni.

 

Ngemva kokuba isignali ye-optical eguquliwe idluliselwe nge-optical fiber, indlela ye-optical ekhiqiza ukubambezeleka okuhambisanayo ikhethwa yi-optical switch array, futhi ukubambezeleka okudingekayo kungatholakala ngokuvula i-optical switch nokuqinisekisa ukuthi ezinye izinkinobho ze-optical zivaliwe. Inzuzo yalolu hlobo lomugqa wokulibaziseka we-optical fiber ukuthi ingafinyelela ukubambezeleka okukhulu, indlela yokuqaphela ilula, futhi izici ezihambisanayo zihlukile ngokuya ngokukhethwa kwezinkinobho ze-optical ezahlukene.
