I-Rof EA modulator laser Umthombo we-pulse laser Imodyuli ye-DFB Laser I-EA laser Umthombo wokukhanya
Umthombo we-laser we-EA modulator we-ROF-EAS uhlanganisa imisebenzi ye-DFB laser kanye ne-EA modulator, nge-chirp ephansi, i-voltage yokushayela ephansi (i-Vpp: 2~3V), ukusetshenziswa kwamandla okuphansi, ukusebenza kahle kokuguquguquka okuphezulu, futhi isetshenziswa kabanzi ku-10Gbps, 40Gbps kanye nezinye izinhlelo zokuxhumana ze-fiber optical ezinesivinini esikhulu kanye nama-photonics e-microwave.

Imojula yokudlulisa ukukhanya okuqondile ye-ROF-DML ye-analog broadband i-module ye-laser eqondile emodareyithiwe
Imodyuli yokukhishwa kwe-optical emission eqondile ye-ROF-DML yochungechunge lwe-analog wideband eqondile eguquguqukayo, isebenzisa i-high linear microwave direct-modulated DFB laser (DML) eqondile, imodi yokusebenza esobala ngokuphelele, i-amplifier yomshayeli we-RF, kanye nokulawula amandla okuzenzakalelayo okuhlanganisiwe (APC) kanye nesekethe yokulawula izinga lokushisa okuzenzakalelayo (ATC), Lokhu kuqinisekisa ukuthi i-laser ingadlulisela amasignali e-microwave RF afinyelela ku-18GHz emabangeni amade, nge-bandwidth ephezulu kanye nempendulo eqondile, enikeza ukuxhumana kwe-fiber eqondile okuphezulu kwezinhlelo zokusebenza ze-microwave ze-analog broadband. Ngokugwema ukusebenzisa izintambo noma ama-waveguides abizayo e-coaxial, umkhawulo webanga lokudlulisela uyasuswa, okuthuthukisa kakhulu ikhwalithi yesignali kanye nokuthembeka kokuxhumana kwe-microwave, futhi kungasetshenziswa kabanzi ekusabalalisweni kwesignali okungenantambo okude, isikhathi kanye nokubhekisela, imigqa ye-telemetry kanye nokubambezeleka kanye nezinye izinkambu zokuxhumana ze-microwave.
