I-Rofea Optoelectronics ineenzuzo ezinkulu kushishino, ezinje ngokwenza ngokwezifiso, iintlobo ngeentlobo, iinkcukacha, ukusebenza kakuhle, nenkonzo egqwesileyo. Kwaye ngo-2016 iphumelele isiqinisekiso seshishini eliphambili laseBeijing, inezatifikethi ezininzi zepatenti, amandla aqinileyo, iimveliso ezithengiswa kwiimarike zasekhaya nakwamanye amazwe, kunye nokusebenza kwayo okuzinzileyo, okugqwesileyo ukuze ifumane udumo lwabasebenzisi ekhaya nakwamanye amazwe!

I-Electro-optic modulator sisixhobo esibalulekileyo sokulawula isignali yelaser eqhubekayo kusetyenziswa idatha, i-radio frequency kunye ne-clock signals. Izakhiwo ezahlukeneyo ze-modulator zinemisebenzi eyahlukeneyo. Nge-optical modulator, ayingotshintsho nje kuphela kumandla e-light wave, kodwa ne-phase kunye ne-polarization state ye-light wave inokuguqulwa. Ii-electro-optic modulators ezisetyenziswa kakhulu zii-Mach-Zehnder intensity modulators kunye nee-phase modulators.

I-Rofea izenzele ngokuzimeleyo i-photodetector edibeneyo ye-photodiode kunye ne-low noise amplifier circuit, ngelixa ibonelela ngeemveliso ezahlukeneyo, kubasebenzisi bophando lwezenzululwazi. Ibonelela ngenkonzo yokwenza ngokwezifiso imveliso esemgangathweni, inkxaso yobugcisa kunye nenkonzo elula emva kokuthengisa. Umgca wemveliso wangoku uquka: i-analog signal photodetector ene-amplification, i-gain adjustable photodetector, i-high speed photodetector, i-snow market detector (APD), i-balance detector, njl.njl.

I-Rofea ibonelela ngeemodyuli ze-laser ezizinzileyo nezithembekileyo zonxibelelwano lwe-optical fiber, i-optical fiber sensing, i-fiber optic gyro kunye nabasebenzisi bonxibelelwano lwe-quantum. Isekethe yokuqhuba kunye nesekethe yokulawula ubushushu edityaniswe kwenye, ukuze abasebenzisi beeyunithi zophando lwezenzululwazi banike icala. Eyona nto iphambili
Iimveliso ziquka umthombo wokukhanya we-DEB laser, umthombo wokukhanya we-broadband, umthombo wokukhanya kwe-pulse, njl.

i-optical amplifier sisixhobo esifumana ukukhanya kwesignali yokufaka kwaye sivelise isignali yokuphuma enamandla aphezulu okubonakalayo. Ngokwesiqhelo, ukungena kunye nokuphuma yimitha yelaser (akufuneki ukuba ibe zezinye iintlobo zemitha yokukhanya), nokuba isasazeka njengemitha yeGaussian kwindawo ekhululekileyo okanye kwifayibha.
Ukwandiswa kwenzeka kwindawo ebizwa ngokuba yi-gain medium, ekufuneka "ipompelwe" (oko kukuthi, inikwe amandla) evela kumthombo wangaphandle. Uninzi lwee-amplifiers ze-optical zipompelwa nge-optical okanye ngombane.

I-Rofea igxile kwicandelo lokusasazwa kwe-RF, ukuqaliswa kwamva nje kothotho lweemveliso zokusasazwa kwe-RF optical fiber. Imodyuli yokusasazwa kwe-RF fiber iguqula ngokuthe ngqo isignali ye-analog RF kwi-transceiver ye-optical, iyidlulisele nge-optical fiber ukuya kwicala elamkelayo,
ize emva koko iyiguqule ibe yisignali ye-RF emva kokuguqulwa kwe-photoelectric. Ezi mveliso zigubungela iibhendi ze-L, S, X, Ku kunye nezinye iibhendi ze-frequency, zisebenzisa i-compact metal casting shell, ukumelana okuhle nokuphazamiseka kwe-electromagnetic, ibhendi yokusebenza ebanzi, ukuthamba okuhle kwibhendi, esetyenziswa kakhulu kwi
i-antenna ye-multimotion yomgca we-microwave delay line, isikhululo sokuphindaphinda, isikhululo somhlaba sesathelayithi kunye nezinye iindawo.

Izixhobo zefayibha ezigcina i-polarization ezifana ne-laser egcina i-polarization, ifayibha egcina i-polarization, i-collimator egcina i-polarization, i-y-waveguide modulator, ifayibha egcina i-polarization, njl. zisetyenziswa kakhulu kwicandelo le-interferometer, i-gyroscope, i-fiber sensing,
njl. Uvavanyo lwezixhobo linyathelo elibalulekileyo kwinkqubo yemveliso. Emva kweminyaka yophando nophuhliso, iRofea Optoelectronics iqokelele uluhlu olupheleleyo lwezisombululo zovavanyo, kubandakanya umthombo wokukhanya kovavanyo, umqhubi welaser, imitha yamandla okukhanya, umvavanyi we-extinction ratio kunye nezinye izixhobo. Ngokweemfuno zabathengi, iRofea Optoelectronics ibonelela ngetshaneli enye/embini yesitishi kunye nenkqubo yovavanyo oludibeneyo lweziteshi ezininzi zovavanyo lozinzo lwexesha elide, oluphucula kakhulu ukusebenza kakuhle kwemveliso.
