Umgca wokulibaziseka weFayibha optic esekelwe kwi-optical switch

Umgaqo wokulibaziseka kweFiber optic line

Kwinkqubo yesignali ye-optical yonke, i-fiber optical inokuqonda imisebenzi yokulibaziseka komqondiso, ukwandisa, ukuphazamiseka, njl. Ukusetyenziswa okufanelekileyo kwale misebenzi kunokuqonda ukuqhutyelwa kolwazi kwintsimi yonke. Phakathi kwabo, umsebenzi we-Delay we-Fiber optical ungenziwa kumgca wokulibaziseka kwe-Fiber optic, uthatha i-fiber optical ye-mode eqhelekileyo njengomzekelo, xa ukuhanjiswa kwe-optical signal yokusebenza kwe-wavelength ye-1550nm, ukuhanjiswa kweemitha ezingama-200 kunokufikelela ukulibaziseka kwe-1μs, kunye nokulahlekelwa kokufakela.04B ehamba kunye ne-04B kuphela. Ngokuthelekisa, ilahleko yokufaka ebangelwa umgca wokulibaziseka we-microwave yendabuko ininzi ye-dB, kwaye umgca wokulibaziseka we-fiber optical unciphisa ukulahlekelwa kokufaka malunga nemiyalelo ye-2 yobukhulu, okuphucula kakhulu ukukhuphisana komgca wokulibaziseka kweFiber optic. Ukongeza, iFiberumgca wokulibazisa opticnazo zineempawu zobukhulu obuncinci, ubunzima obukhanyayo, imveliso yokulibaziseka okukhulu kwe-bandwidth, isakhono esinamandla sokuphazamiseka kwe-anti-electromagnetic, kwaye ube ngumntu okhuphisana owomeleleyo wemigca yokulibaziseka ye-microwave, kwaye inokutshintsha ngokupheleleyo imigca yokulibaziseka ye-microwave kwiindawo ezininzi. Xa kuthelekiswa nomgca wokulibaziseka we-microwave yendabuko, umgca wokulibazisa i-fiber optical linexesha eliphezulu lemveliso ye-bandwidth, ebonisa ukuba inkqubo inesisombululo esilungileyo sokulinganisa i-frequency, uvakalelo oluphezulu kunye nokukwazi ukuphazamisa umqondiso ophezulu, kwaye unokuhlangabezana neemfuno zeenkqubo eziphezulu ze-radar ezifana nemigca yokulibaziseka. Kwaye FDL ukusebenza frequency iphezulu kakhulu, inokuba phezulu kakhulu ngaphezu 100GHz, xa kuthelekiswa nomphezulu acoustic iliza umgca ukulibaziseka amakhulu megahertz ukusebenza frequency kunye neCCD ukulibaziseka umgca amashumi megahertz ukusebenza frequency xa kuthelekiswa nemiyalelo eziliqela zobukhulu, kwaye isekelwe kwixa elizayo unxibelelwano radar kunye nezinye iinkqubo ziya kutshintshela kwi-trend of frequency band, FDL yinzuzo ebalulekileyo; Ukongezelela, umgca wokulibazisa ifayibha unalo uphawu lokuba ilahleko yokulibaziseka kweyunithi izimele ngokuphindaphindiweyo. Iinzuzo ezizodwa zale migca yokulibazisa i-fiber optic ngokungathandabuzekiyo ingqina amandla ayo ekusetyenzweni komqondiso.

Ukusetyenziswa komgca wokulibaziseka kweFiber optic

Umsebenzi osisiseko weFiber optic umgca wokulibaziseka ukulibazisa umqondiso, onokuqonda umsebenzi wokugcinwa kwezinto zonke kunye nokulingana kwe-shift ngokusebenzisa ukulibaziseka, kwaye unoluhlu olubanzi lwezicelo kwi-radar ye-radar, i-fiber optical communication system, i-optical computer system kunye ne-electronic countermeasures. Kwinqanaba le-radar yoluhlu, i-eriyali yoluhlu olunezigaba yinxalenye engundoqo, umsebenzi ophambili we-eriyali yoluhlu kukutshintsha umsebenzi wepateni we-antenna edibeneyo, ukuze kuphunyezwe utshintsho lwemilo ye-eriyali ye-antenna kunye nokuskena ngokukhawuleza kwe-beam, kwaye lo msebenzi uphunyezwa ngokulawula i-amplitude kunye nesigaba solwazi lwe-indipenna iyunithi ye-indipenna, iyunithi yokulibaziseka. Xa kuthelekiswa nomgca wokulibaziseka we-microwave, i-FDL ine-bandwidth enkulu, kwaye akukho ngxaki ye-beam tilt. Kwi-eriyali yoluhlu olulawulwa ngokubonakalayo, i-FDL inokuqonda ukwabiwa kwesigaba esichanekileyo kunye nolawulo lwesiginali ye-microwave kwaye isuse ingxolo ehambelana nomqondiso we-echo, ukuze i-FDL ibe lolona khetho lulungileyo kwi-eriyali yoluhlu olunezigaba. Kwi-radar target simulator, i-FDL isetyenziselwa ukulinganisa iimpawu zemigama eyahlukeneyo. Ngeemfuno zenkqubo ye-radar yanamhlanje ye-radar ekujoliswe kuyo, njengebhendi ye-frequency ephezulu, isantya sokutshintsha okujoliswe kuyo ngokukhawuleza kunye nomgama omde wokulinganisa ojoliswe kuyo, imigca yokulibaziseka yendabuko ibe kude nokuhlangabezana neemfuno zenkqubo ye-radar, ngoko ke umgca wokulibaziseka we-fiber optic uye waba kuphela umgca wokulibaziseka osebenzayo. Ukongeza koku ngasentla, kwinkqubo yonxibelelwano lwefiber optical, i-FDL inokuqonda kwakhona umsebenzi wekhowudi yomqondiso kunye ne-caching. Isishwankathelo, kunokubonwa ukuba umgca wokulibaziseka we-fiber optic unezicelo ezibalulekileyo kunye nesimo esingenakuthathelwa indawo kwiindawo ezininzi, ngoko ke uphononongo lomgca wokulibaziseka we-fiber optic ephezulu lunokubaluleka okukhulu kwezesayensi ekusebenziseniitekhnoloji yeefoton zemicrowave.

Uyilo lomgca wokulibaziseka kweFiber optic

Umgca wokulibazisa i-fiber optic esekelwe kwi-optical switch ikhetha iindlela ezahlukeneyo ze-optical ukufezekisa ukulibaziseka kwexesha elihlukeneyo ngokutshintshwa kwe-optical. Umgaqo osisiseko wolu hlobo lwesikimu kukufezekisa ukulibaziseka okuhlukeneyo ngokuguqula indlela ye-optical. Ingumgca wokulibaziseka oqhelekileyo weFiber optic, kwaye isakhiwo sayo esiqhelekileyo siboniswe kumzobo.

 

Emva kokuba isignali ye-optical modulated ihanjiswe nge-fiber optical, indlela ye-optical eyenza ukulibaziseka okuhambelanayo ikhethwa yi-optical switch array, kwaye ukulibaziseka okufunekayo kunokufezekiswa ngokuvula i-optical switch kunye nokuqinisekisa ukuba enye i-optical switches ivaliwe. Inzuzo yolu hlobo lomgca wokulibazisa i-fiber optical kukuba inokufikelela ukulibaziseka okukhulu, indlela yokuqonda ilula, kwaye iimpawu ezihambelanayo zihluke ngokukhetha ukutshintshwa kwee-optical ezahlukeneyo.
