Izici ezibalulekile kanye nentuthuko yakamuva yei-Photodetector yesivinini esiphezulu
Ngokuthuthuka kwesayensi nobuchwepheshe, ukusetshenziswa kwe-Photodetector yesivinini esikhulu (imodyuli yokuthola okubonakalayo) emikhakheni eminingi ibanzi kakhulu. Leli phepha lizokwethula i-10G enesivinini esikhuluIsitholi sezithombe(imojuli yokuthola ukukhanya) ehlanganisa i-photodiode ye-avalanche yokusabela okusheshayo (i-APD) kanye ne-amplifier yomsindo ophansi, inokufakwayo kwe-fiber coupled yemodi eyodwa/yemodi eminingi, okukhiphayo kwe-SMA connector, futhi inokuzuza okuphezulu, ukuzwela okuphezulu, okukhiphayo kwe-AC coupled, kanye nokuzuza okuphansi.
Imodyuli isebenzisa i-InGaAs APD detector enobubanzi be-spectral obungu-1100 ~ 1650nm, obufanele izinhlelo zokudlulisa i-optical fiber esheshayo kanye nokutholwa kwe-optical pulse okusheshayo. Emkhakheni wokuxhumana kwe-optical, ukuzwela kanye nesivinini sama-photodetector kuyizinkomba zokusebenza ezibalulekile. Ukuzwela okuphezulu kwemodyuli kufinyelela ku--25dBm kanti amandla e-saturation optical angama-0dBm, okuqinisekisa ukudluliswa kwedatha okuthembekile ngaphansi kwezimo zamandla e-optical aphansi.
Ngaphezu kwalokho, imodyuli iphinde ihlanganise i-preamplifier kanye ne-booster circuit, enganciphisa ngempumelelo umsindo futhi ithuthukise isilinganiso sesiginali kuya komsindo. Umphumela ohlanganisiwe we-AC unganciphisa ithonya lengxenye ye-DC futhi uthuthukise ikhwalithi yesiginali. Isici se-gain flatness senza imodyuli ibe ne-gain eqinile kuma-wavelength amaningi, okwenza ngcono ikhwalithi yesiginali.
Emkhakheni wokusetshenziswa, le module isetshenziswa kakhulu ekutholeni i-pulse esheshayo, ukuxhumana kwe-optical space okusheshayo kanye nokuxhumana kwe-optical fiber okusheshayo. Ngokuthuthuka kobuchwepheshe, isidingo kulezi zinkambu siyanda. Ngakho-ke, ukuthuthukiswa kanye nokusetshenziswa kwale module kubaluleke kakhulu.
Ukusebenza kanye nokusetshenziswa kwemodyuli kuyenza ibe ngenye yezinhle kakhuluama-photodetector athuthukisiweImakethe namuhla. Inezici zokusebenza okuphezulu, ukuzinza okuphezulu kanye nokuthembeka okuphezulu, futhi ingahlangabezana nezidingo zohlelo lokusebenza lwezinkambu ezahlukene. Ekuthuthukisweni kwesikhathi esizayo, ngentuthuko eqhubekayo yobuchwepheshe kanye nokwanda okuqhubekayo kwezinkambu zohlelo lokusebenza, imodyuli izosetshenziswa kabanzi futhi ikhuthazwe kakhulu.
