Iyini i-FiberUmugqa Wokulibaziseka OpticI-OFDL
Umugqa Wokulibaziseka We-Fiber Optical(OFDL) iyithuluzi elingafinyelela ukulibaziseka kwesikhathi kwezimpawu zokukhanya. Ngokusebenzisa ukulibaziseka, lingafinyelela ukushintsha kwesigaba, isitoreji se-all-optical kanye neminye imisebenzi. Inezinhlelo zokusebenza eziningi ku-radar ye-array ehlukaniswe ngezigaba, izinhlelo zokuxhumana ze-fiber optic, izindlela zokumelana ze-elekthronikhi, ucwaningo lwesayensi kanye nokuhlolwa, kanye neminye imikhakha. Lesi sihloko sizoqala ezimisweni eziyisisekelo zemigqa yokulibaziseka ye-fiber optic, sigxile ezimweni zohlelo lokusebenza kanye nendlela yokukhetha umugqa wokulibaziseka we-fiber optic ofanele.
Isimiso sokusebenza
Isimiso esiyisisekelo somugqa wokulibaziseka we-fiber optic ukuthi isignali yokukhanya okufanele ibambezeleke idluliselwa ngobude obuthile bekhebula le-fiber optic, futhi ngenxa yesikhathi esidingekayo sokudlulisa ukukhanya kukhebula le-fiber optic, ukubambezeleka kwesikhathi kwesignali yokukhanya kufinyelelwa. Njengoba kuboniswe kuMfanekiso 1, umugqa wokulibaziseka we-fiber optic olula kakhulu uhlelo olwakhiwe ngamadivayisi anjenge-laser, ama-modulators, ama-transmission fibers, kanye nama-photodetector anomsebenzi wokulibaziseka kwesignali. Isimiso sokusebenza: Isignali ye-RF okufanele idluliselwe kanye nesignali yokukhanya ekhishwa yi-laser kufakwa kuma-modulators ahlukahlukene. Ama-modulators aguqula isignali ye-RF ibe ukukhanya ukuze akhe isignali yokukhanya ephethe ulwazi lwe-RF. Ulwazi lwe-RF oluphethe isignali yokukhanya luxhunywe kusixhumanisi se-fiber optic sokudlulisa, lubambezeleke isikhathi esithile, bese lufika ku-umshini wokuthola izithombeI-photodetector iguqula isignali ye-optical etholakele ephethe ulwazi lwe-RF ibe yi-electrical signal output.
Umfanekiso 1 Ukwakheka Okuyisisekelo KwaloUmugqa Wokulibaziseka We-Optic FiberI-OFDL
Izimo zohlelo lokusebenza
1. I-radar ye-Phased array: Ingxenye eyinhloko ye-radar ye-phased array yi-antenna ye-phased array. Ama-antenna e-radar endabuko awahlangabezani nezidingo zezinhlelo ze-radar, kuyilapho imigqa ye-fiber optic delay inezinzuzo zayo zokusebenza ezihlukile ekusetshenzisweni kwama-antenna e-phased array. Ngakho-ke, imigqa ye-fiber optic delay inokubaluleka okukhulu kwesayensi ku-radar ye-phased array.
2. Uhlelo lokuxhumana lwe-Fiber optic: Imigqa yokulibaziseka ye-fiber optic ingasetshenziswa ukusebenzisa izinhlelo ezithile zokufaka ikhodi. Ngokungenisa ukulibaziseka okuhlukene ngezikhathi ezahlukene, kungakhiqizwa izimpawu zokufaka ikhodi ezinamaphethini athile, okuzuzisa ekuthuthukiseni ikhono lokulwa nokuphazamiseka kwezimpawu ezinhlelweni zokuxhumana zedijithali. Ngaphezu kwalokho, ingasetshenziswa futhi njengesitoreji sesikhashana (i-cache) ukugcina idatha ethile okwesikhashana, njalo njalo. Ngamafuphi, imigqa yokulibaziseka ye-fiber optic inezinhlelo zokusebenza eziningi emikhakheni eminingi ngenxa ye-bandwidth ephezulu, ukulahlekelwa okuphansi, kanye nokumelana nokuphazamiseka kwe-electromagnetic. Kungakhathaliseki ukuthi kusemkhakheni wokuxhumana, i-radar, i-navigation, noma i-medical imaging, zonke zidlala indima ebalulekile.
