Umgca wokulibaziseka kwe-Fiber optic osekelwe kwiswitshi ye-optical

Umgaqo womgca wokulibaziseka we-Fiber optic

Kwinkqubo yesignali ye-all-optical, i-optical fiber inokufezekisa imisebenzi yokulibaziseka kwesignali, ukwandisa, ukuphazamiseka, njl. Ukusetyenziswa ngokufanelekileyo kwale misebenzi kunokufezekisa ukucutshungulwa kolwazi kwicandelo le-all-optical. Phakathi kwazo, umsebenzi we-Delay we-optical Fiber unokwenziwa ube ngumgca wokulibaziseka we-Fiber optic, kuthathwa i-optical fiber eqhelekileyo yemowudi enye njengomzekelo, xa ukudluliselwa kobude bomsebenzi wesignali ye-optical ye-1550nm, ukudluliselwa kweemitha ezingama-200 kunokufezekisa ukulibaziseka kwe-1μs, kwaye ilahleko yokufaka ehamba nayo yi-0.04dB kuphela. Xa kuthelekiswa, ilahleko yokufaka ebangelwa ngumgca wokulibaziseka we-microwave wendabuko yi-dB ezininzi, kwaye umgca wokulibaziseka we-optical fiber unciphisa ilahleko yokufaka phantse nge-odolo ezimbini zobukhulu, nto leyo ephucula kakhulu ukukhuphisana komgca wokulibaziseka we-Fiber optic. Ukongeza, i-Fiberumgca wokulibaziseka we-opticZineempawu zobukhulu obuncinci, ubunzima obulula, imveliso ye-bandwidth yokulibaziseka enkulu, amandla okuphazamiseka okulwa ne-electromagnetic, kwaye zibe ngumncintisani onamandla wemigca yokulibaziseka ye-microwave, kwaye zinokuthatha indawo ngokupheleleyo yemigca yokulibaziseka ye-microwave kwiindawo ezininzi. Xa kuthelekiswa nomgca wokulibaziseka we-microwave wendabuko, umgca wokulibaziseka we-optical fiber unemveliso ye-bandwidth yexesha eliphezulu, nto leyo ebonisa ukuba inkqubo inesisombululo esihle sokulinganisa amaza, uvakalelo oluphezulu kunye nokukwazi ukuvalela isignali ephezulu, kwaye inokuhlangabezana neemfuno zeenkqubo ze-radar ezinesisombululo esiphezulu ezifana nemigca yokulibaziseka. Kwaye i-frequency yokusebenza ye-FDL iphezulu kakhulu, ingaba phezulu kakhulu kune-100GHz, xa kuthelekiswa nomgca wokulibaziseka we-acoustic wave wamakhulu e-megahertz yokusebenza rhoqo kunye nomgca wokulibaziseka we-CCD wamashumi e-megahertz yokusebenza rhoqo xa kuthelekiswa nemiyalelo emininzi yobukhulu, kwaye ngokusekelwe kwi-radar yonxibelelwano yexesha elizayo kunye nezinye iinkqubo ziya kutshintshela kwi-trend ye-high frequency band, i-FDL yinzuzo ebalulekileyo; Ukongeza, umgca wokulibaziseka we-fiber ukwanophawu lokuba ilahleko yokulibaziseka kweyunithi ayixhomekekanga kumaza amaninzi. Iingenelo ezizodwa zale migca yokulibaziseka ye-fiber optic ngokuqinisekileyo zingqina amandla ayo ekucutshungulweni kwesignali.

Ukusetyenziswa komgca wokulibaziseka we-Fiber optic

Umsebenzi osisiseko womgca wokulibaziseka we-Fiber optic kukulibaziseka kwesignali, enokufezekisa umsebenzi wokugcina i-all-optical kunye nokulingana kwe-shift ngokusebenzisa ukulibaziseka, kwaye inoluhlu olubanzi lwezicelo kwi-radar ye-phased array, inkqubo yonxibelelwano lwe-optical fiber, inkqubo yekhompyutha ye-optical kunye neendlela zokulinganisa ze-elektroniki. Kwi-radar ye-phased array, i-antenna ye-phased array yeyona nto iphambili, umsebenzi oyintloko we-antenna ye-phased array kukutshintsha umsebenzi wepateni ye-synthesized beam, ukuze kufezekiswe utshintsho kwimo ye-antenna beam kunye nokuskena ngokukhawuleza kwe-beam, kwaye lo msebenzi ufezekiswa ngokulawula i-amplitude kunye nolwazi lwesigaba sesignali kwiyunithi ye-antenna, ngoko ke umgca wokulibaziseka yinxalenye ebalulekileyo. Xa kuthelekiswa nomgca wokulibaziseka we-microwave, i-FDL ine-bandwidth enkulu, kwaye akukho ngxaki yokuthambekela kwe-beam. Kwi-antenna ye-phased array elawulwa ngokukhanya, i-FDL inokufezekisa ukwabiwa kwesigaba ngokuchanekileyo kunye nolawulo lwesignali ye-microwave kwaye isuse ingxolo ehambelanayo yesignali ye-echo, ngoko ke i-FDL inokuba lolona khetho lubalaseleyo kwi-antenna ye-phased array. Kwi-radar target simulator, i-FDL isetyenziselwa ukulinganisa imiqondiso yemigama eyahlukeneyo. Ngenxa yeemfuno zenkqubo yeradar yanamhlanje ye-radar target simulator, njenge-high frequency band, isantya sokutshintsha ithagethi ngokukhawuleza kunye nomgama wokulinganisa ithagethi ende, imigca yokulibaziseka yendabuko ayikwazanga ukuhlangabezana neemfuno zenkqubo yeradar, ngoko ke i-fiber optic delay line ibe yiyo yodwa i-delay line esebenzayo. Ukongeza koku kungasentla, kwinkqubo yonxibelelwano lwe-optical fiber, i-FDL inokufezekisa umsebenzi wokubhala ikhowudi yesignali kunye ne-caching. Ngamafutshane, kunokubonwa ukuba i-fiber optic delay line inezicelo ezibalulekileyo kunye nemeko engenakutshintshwa kwiindawo ezininzi, ngoko ke uphando lwe-high-performance fiber optic delay line lubaluleke kakhulu kwisayensi ekusebenziseniiteknoloji ye-photon ye-microwave.

Uyilo lomgca wokulibaziseka we-Fiber optic

Umgca wokulibaziseka we-fiber optic osekelwe kwiswitshi yokukhanya ukhetha iindlela ezahlukeneyo ze-optical ukuze kufezekiswe ukulibaziseka kwexesha okwahlukeneyo ngeswitshi yokukhanya. Umgaqo osisiseko wolu hlobo lweskimu kukufezekisa ukulibaziseka okwahlukeneyo ngokutshintsha indlela yokukhanya. Ngumgca wokulibaziseka we-Fiber optic oqhelekileyo ohlukeneyo, kwaye isakhiwo sawo esiqhelekileyo siboniswe kumfanekiso.

 

Emva kokuba isignali ye-optical eguquliweyo idluliselwe nge-optical fiber, indlela ye-optical evelisa ukulibaziseka okuhambelanayo ikhethwa yi-optical switch array, kwaye ukulibaziseka okufunekayo kunokufezekiswa ngokuvula i-optical switch nokuqinisekisa ukuba ezinye ii-optical switches zivaliwe. Inzuzo yolu hlobo lomgca wokulibaziseka kwe-optical fiber kukuba inokufezekisa ukulibaziseka okukhulu, indlela yokufezekisa ilula, kwaye iimpawu ezihambelanayo zahlukile ngokokukhethwa kwee-optical switches ezahlukeneyo.
