Izicelo Ezintsha zeIsitholi Sezithombe Esisheshayo Esiphezulu
Ukukhanya, okukhanyayo kangangokuthi cishe kungabonakali, kodwa kunquma ukushaya kwenhliziyo kokuxhumana kwesikhathi esizayo… Ezweni le-gigabit lapho izimpawu zokukhanya zihamba khona yonke indawo, i-nanosecond ngayinye yokulibaziseka ingasho ukulahlekelwa idatha ebalulekile. Ukutholwa kokushaya kwenhliziyo kokukhanya okushesha kakhulu, izinhlelo zokuxhumana ze-43Gbit/s, izixhumanisi ze-microwave photonic… Lezi zinsimu ezisezingeni eliphezulu zihlala zibuza: Ingabe kukhona uhlelo lokuthola i-optoelectronic oluhlanganisa ukuzwela okuphezulu kakhulu nokuphendula okusheshayo kakhulu?
Namuhla, uchungechunge lwe-ROF-PT lokukhulisa ijubane eliphezuluumshini wokuthola izithombeAmamojula anikeze impendulo ecacile neqondile.
Ngokuhlanganisa ngokujulile isivinini esikhuluIzitholi ze-PINNgama-chip amplification e-TIA anembile, sidale isixhumanisi esiphelele sokwenza ngcono isignali kusukela kokufaka kuya kokukhiphayo. Ukuhlanganiswa kwefayibha yemodi eyodwa kuqinisekisa ukuthi okufakwayo kwesignali kuhlanzekile, izixhumi ze-K zithola okukhiphayo okuzinzile nokusebenzayo, kanye ne-bandwidth efika ku-40GHz kanye nesikhathi sokuphendula esingaphansi kwama-10ps kwenza kube nzima ukufihla umzila wesignali yokukhanya. Kungakhathaliseki ukuthi ukubanjwa okubanzi kobubanzi be-spectral ye-1200-1650nm noma ibhalansi yokuzuza okuphezulu, ukuzwela okuphezulu kanye nokuthamba kwenzuzo, uchungechunge lwe-ROF-PT luhlala lulwela ukufeza ibhalansi enhle phakathi kwesivinini nokunemba.
Ibhekene nezidingo eziqinile zesistimu yokuxhumanisa i-ROF microwave noma inselele yezimpawu ezibuthakathaka ekuzweleni kwe-Brillouin, ingaphinde isekele umkhiqizo ohlukile owenziwe ngokwezifiso, okwenza ikwazi ukuhlanganiswa kalula nomklamo wakho wesistimu ephezulu.
Ukwandiswa kwe-beam yesivinini esiphezulu yochungechunge lwe-ROF-PTisitholi se-photoelectricImodyuli inikeza onjiniyela ikhambi elisebenza kahle nelithembekile, elibenza bakwazi ukusingatha imisebenzi eyinkimbinkimbi yokuthola isignali yokukhanya ngokuthula okukhulu nokuzethemba. Lena akuyona nje imodyuli; futhi iyisisekelo sokusebenza kwezinhlelo zokusebenza zobuchwepheshe bokukhanya zesikhathi esizayo - lapha, indlela yokukhanya ithwetshulwa ngokunembile, futhi ijubane lichazwa yithi ngokuhlanganyela.
Incazelo Yomkhiqizo:
I-ROF-PT series high-speed Photodetector ihlanganisa i-PIN detector yesivinini esiphezulu kanye ne-TIA amplification chip. Ine-single-mode fiber coupling input kanye ne-K connector output. Ifaka i-high gain, high sensitivity, i-AC coupling output, kanye nezici ze-flat gain. I-differential output eyenziwe ngokwezifiso iyatholakala. Isetshenziswa kakhulu ezinhlelweni zokudlulisa i-optical fiber zesivinini esiphezulu, i-ROF, kanye nezinhlelo zokuzwa i-optical fiber, njll.
Izici zomkhiqizo:
Ibanga le-Spectral: 1200 - 1650 nm
Ububanzi be-bandwidth: 10 GHz, 20 GHz, 40 GHz
Isikhathi sokuphendula: Ngaphansi kwama-10 ps
Izinkambu zohlelo lokusebenza:
Ukutholwa kwe-optical pulse ngesivinini esiphezulu (43 Gbit/s)
Uhlelo lokuxhumana ngefayibha yokubona
Isixhumanisi se-microwave
Uhlelo lokuzwa i-Birefringent optical fiber
Isikhathi sokuthunyelwe: Jan-20-2026
