Izici ezibalulekile kanye nenqubekelaphambili yakamuva yeisivinini esiphezulu se-Photodetector
Ngokuthuthuka kwesayensi nobuchwepheshe, ukusetshenziswa kwe-Photodetector enesivinini esikhulu (imojula yokuthola i-optical) emikhakheni eminingi lubanzi kakhulu. Leli phepha lizokwethula i-10G high-speedIsithwebuli sezithombe(imojula yokubona okubonakalayo) ehlanganisa i-avalanche photodiode (APD) yokusabela ngesivinini esiphezulu kanye nesikhulisamandla somsindo ophansi, inokufakwayo okuhlanganisiwe kwemodi eyodwa/imodi eminingi ye-fiber, okukhiphayo kwesixhumi se-SMA, futhi inenzuzo ephezulu, ukuzwela okuphezulu, okukhiphayo okuhambisana ne-AC , kanye nenzuzo ephansi.
Imojula isebenzisa umtshina we-InGaAs APD onebanga le-spectral elingu-1100 ~ 1650nm, elifanele amasistimu okudlulisa i-fiber optical ngesivinini esiphezulu kanye nokutholwa kwe-pulse optical ngesivinini esiphezulu. Emkhakheni wokuxhumana optical, ukuzwela kanye nesivinini se-photodetectors yizinkomba zokusebenza ezibalulekile. Ukuzwela okuphezulu kwemojula kufinyelela -25dBm futhi amandla optical saturation yi-0dBm, iqinisekisa ukudluliswa kwedatha okuthembekile ngaphansi kwezimo zamandla aphansi optical.
Ngaphezu kwalokho, imojula iphinde ihlanganise i-preamplifier ne-booster circuit, enganciphisa ngempumelelo umsindo futhi ithuthukise isignali kumsindo wesilinganiso. Okukhiphayo okuhlanganisiwe kwe-AC kunganciphisa umthelela wengxenye ye-DC futhi kuthuthukise ikhwalithi yesiginali. Isici sokuthola isicaba sivumela imojuli ukuthi ibe nenzuzo ezinzile kumaza wamaza amaningi, ithuthukise ngokwengeziwe ikhwalithi yesiginali.
Emkhakheni wohlelo lokusebenza, i-module isetshenziswa kakhulu ekuboneni ukushaya kwe-pulse ngesivinini esikhulu, ukuxhumana kwe-optical space ngesivinini esikhulu kanye nokuxhumana kwe-fiber optical ngesivinini esikhulu. Ngokuthuthuka kobuchwepheshe, isidingo kule mikhakha siyanda. Ngakho-ke, ukuthuthukiswa nokusebenzisa le mojuli kubaluleke kakhulu.
Ukusebenza kwemojula nokusebenza kwayo kuyenza ibe enye ehamba phambiliama-photodetectors athuthukileemakethe namuhla. Inezici zokusebenza okuphezulu, ukuzinza okuphezulu nokuthembeka okuphezulu, futhi ingahlangabezana nezidingo zohlelo lokusebenza lwemikhakha ehlukene. Ekuthuthukisweni okuzayo, ngenqubekelaphambili eqhubekayo yobuchwepheshe kanye nokwandiswa okuqhubekayo kwezinkambu zohlelo lokusebenza, imojuli izosetshenziswa kabanzi futhi ithuthukiswe.
