Fiber optic kunonoka mutsara unobva pane optical switch

Nheyo yeFiber optic kunonoka mutsara

Mune ese-optical signal processing, optical fiber inogona kuona mabasa ekunonoka kwechiratidzo, kuwedzera, kupindira, nezvimwewo. Kushandisa zvine musoro kweaya mabasa kunogona kuona kugadziridzwa kweruzivo munharaunda yese-yemaziso. Pakati pavo, Kunonoka kushanda kweFiber optical kunogona kuitwa muFiber optic kunonoka mutsara, kutora yakajairika-mode optical fiber semuenzaniso, apo kutapurirwa kwechiratidzo chemaziso chinoshanda wavelength ye1550nm, kutumirwa kwemamita 200 kunogona kuwana kunonoka kwe1μs, uye inopindirana yekuisa kurasikirwa inongowanikwa 04B chete. Mukuenzanisa, kurasikirwa kwekuisa kunokonzerwa neyakajairwa microwave kunonoka mutsara yakawanda ye dB, uye optical fiber kunonoka mutsara inoderedza kurasikirwa kwekuisa neinoda 2 mirairo yehukuru, iyo inovandudza zvakanyanya kukwikwidza kweFiber optic kunonoka mutsara. Mukuwedzera, Fiberoptic kunonoka mutsarazvakare vane hunhu hwehukuru hudiki, huremu huremu, hombe kunonoka bandwidth chigadzirwa, yakasimba anti-electromagnetic kupindira kugona, uye kuva mukwikwidzi akasimba wemirayiro yekunonoka mitsara, uye inogona kutsiva zvachose microwave kunonoka mitsara muminda yakawanda. Kuenzaniswa neyakajairwa microwave kunonoka mutsara, iyo optical fiber kunonoka mutsara ine yakakwira nguva bandwidth chigadzirwa, iyo inoratidza kuti sisitimu ine sarudzo yakanaka yekuyerwa kwefrequency, kunzwisiswa kwepamusoro uye kugona kwechiratidzo chepamusoro, uye inogona kusangana nezvinodiwa zvepamusoro-resolution radar masisitimu akadai sekunonoka mitsetse. Uye FDL inoshanda frequency yakakwirira kwazvo, inogona kunge yakakwira zvakanyanya kupfuura 100GHz, kana ichienzaniswa neyepamusoro acoustic wave kunonoka mutsara wemazana e megahertz inoshanda frequency uye CCD kunonoka mutsara wemakumi emakumi e megahertz inoshanda frequency kana ichienzaniswa nemirairo yakawanda yehukuru, uye zvichibva pane ramangwana rekukurukurirana radar uye mamwe masisitimu achachinja kune maitiro eiyo high frequency band, FDL ibasa rakakosha; Mukuwedzera, iyo fiber kunonoka mutsara inewo hunhu hwekuti iyo unit inononoka kurasikirwa yakazvimirira pane frequency. Izvo zvakasarudzika zvakanakira iyi fiber optic kunonoka mitsetse pasina mubvunzo inoratidza kugona kwayo mukugadzirisa zviratidzo.

Kushandiswa kweFiber optic kunonoka mutsara

Basa rinokosha reFiber optic kunonoka mutsara nderokunonoka chiratidzo, chinogona kuona basa rekuchengetedza kwese-optical uye kushandura kuenzana nekushandisa kunonoka, uye ine huwandu hwakawanda hwemashandisirwo muzvikamu zvakagadziriswa radar, optical fiber communication system, optical computer system uye magetsi anopikisa. Muchikamu cheradhi radhi, yakaganhurwa antenna ndiyo yakakosha chikamu, basa guru reiyo yakapetwa array antenna ndere kushandura chimiro chebasa redanda rakagadzirwa, kuitira kuti uwane shanduko yeantenna danda chimiro uye nekukasira kutarisisa kwedanda, uye basa iri rinowanikwa nekudzora amplitude uye chikamu chinononoka chikamu cheiyo indipenna mutsara. Kuenzaniswa ne microwave kunonoka mutsara, FDL ine yakakura bandwidth, uye hapana dambudziko rekutenderera kwedanda. Mune antenna inodzorwa inodzorwa inodzorwa, FDL inogona kuona kwakaringana chikamu chekugova uye kutonga kweiyo microwave siginecha uye kubvisa ruzha rwakabatana rweiyo echo chiratidzo, saka FDL inogona kuve yakanakisa sarudzo muchikamu array antenna. Mune radar target simulator, FDL inoshandiswa kutevedzera masaini ezvinhambwe zvakasiyana. Nezvinodiwa zvemazuva ano radar system yeradar target simulator, senge yakakwira frequency bhendi, kukurumidza chinangwa switching spidhi uye kureba kwakananga simulation kureba, tsika yekunonoka mitsetse yanga iri kure nekuzadzisa zvinodiwa zveradar system, saka fiber optic yekunonoka mutsara yave iyo chete inoshanda yekunonoka mutsara. Pamusoro pezviri pamusoro, mune optical fiber communication system, FDL inogona zvakare kuona basa rechiratidzo coding uye caching. Muchidimbu, zvinogona kuoneka kuti fiber optic kunonoka mutsara ine zvakakosha maapplication uye chimiro chisingadzoreki mundima dzakawanda, saka kudzidza kwepamusoro-kuita fiber optic kunonoka mutsara kune hukuru hwesainzi kukosha kwekushandiswa kwe.microwave photon teknolojia.

Dhizaini yeFiber optic kunonoka mutsara

Iyo fiber optic yekunonoka mutsara yakavakirwa pane optical switch inosarudza nzira dzakasiyana dzemaziso kuti uwane nguva dzakasiyana kunonoka kuburikidza neiyo optical switch. Nheyo yekutanga yerudzi urwu rwechirongwa ndeyekuwana kunonoka kwakasiyana nekushandura nzira yekuona. Iyo yakajairika discrete Fiber optic kunonoka mutsara, uye yakajairika chimiro chinoratidzwa mumufananidzo.

 

Mushure mokunge iyo modulated optical signal inotumirwa kuburikidza nefiber optical, nzira ye optical iyo inogadzira kunonoka kunoenderana inosarudzwa ne optical switch array, uye kunonoka kunodiwa kunogona kuwanikwa kuburikidza nekubatidza optical switch uye nekuona kuti dzimwe shanduko dzemaziso dzakadzimwa. Kubatsira kwerudzi urwu rweoptical fiber kunonoka mutsara ndeyekuti inokwanisa kuwana kunonoka kukuru, nzira yekuziva iri nyore, uye maitiro anowirirana akasiyana maererano nekusarudzwa kwekuchinja kwakasiyana-siyana.
