UbuchuleI-RF ngaphezulu kwefayibhaisisombululo
Kule meko yanamhlanje inzima ngakumbi ye-electromagnetic kunye nokuvela okuqhubekayo kokuphazamiseka kwesignali, indlela yokufikelela ekudlulisweni okuphezulu, okude kunye nokuzinzileyo kwemiqondiso yombane ye-wideband ibe ngumceli mngeni ophambili kwicandelo lokulinganisa nokuvavanya kwemizi-mveliso. Ikhonkco le-RF over fiber analog broadband optical transceiver ngokuchanekileyo liyinto entsha.ukudluliselwa kwefayibha ye-opticalisisombululo esenzelwe ukujongana nalo mceli mngeni.
Esi sixhobo sixhasa ukuqokelelwa kunye nokudluliselwa kwemiqondiso ye-wideband ngexesha langempela ukusuka kwi-DC ukuya kwi-1GHz, kwaye sinokuhlengahlengiswa ngokulula kwizixhobo ezahlukeneyo zokufumanisa, kubandakanya ii-current probes, ii-high-voltage probes kunye nezinye izixhobo zokulinganisa i-high-frequency. Isiphelo saso sokudlulisa sixhotyiswe nge-1 MΩ/50 Ω switchable BNC input interface, equka ukuhambelana okubanzi. Ngexesha lokucubungula imiqondiso, imiqondiso yombane iyaguqulwa kwaye iguqulwe ibe yimiqondiso ye-optical, emva koko idluliselwa kwisiphelo sokwamkela ngee-fibers ze-optical ze-single-mode kwaye ibuyiselwe ngokuchanekileyo kwimiqondiso yombane yokuqala yi-receiving module.
Kubalulekile ukukhankanya ukuba uthotho lwe-R-ROFxxxxT ludibanisa indlela yokulawula inqanaba elizenzekelayo (i-ALC), enokumelana ngempumelelo nokuguquguquka kwesignali okubangelwa kukulahleka kwefayibha kwaye iqinisekise ukusebenza rhoqo ngexesha lokudluliselwa komgama omde. Ukongeza, imodyuli yokudluliselwa ixhotyiswe nge-attenuator eguquguqukayo nehlengahlengiswayo, exhasa uhlengahlengiso oluthathu oluguquguqukayo lwe-1:1/10:1/100:1. Oku kwenza abasebenzisi bakwazi ukuphucula inqanaba lokwamkela isignali ngokusekelwe kwiimeko zokwenyani kwaye bandise uluhlu oluguquguqukayo lwenkqubo.
Ukuze kuhlangatyezwane neemfuno zovavanyo lwasentsimini okanye oluhambayo, olu luhlu lweemodyuli luxhasa umbane webhetri kunye nolawulo olukude, kwaye lunemowudi yokulinda ekrelekrele engena ngokuzenzekelayo kwimeko yamandla aphantsi ngexesha lokungasebenzisi, nto leyo eyandisa ubomi bebhetri yesixhobo ngempumelelo. Izibane ze-LED kwiphaneli engaphambili zibonelela ngempendulo yexesha langempela malunga nemeko yokusebenza, nto leyo ephucula ngakumbi ukusebenza kwesixhobo kunye nokusebenza kwaso.
Nokuba kwiimeko ezifana nokubeka esweni amandla, uvavanyo lwerediyo, okanye iimvavanyo zophando lwesayensi, uthotho lwe-R-ROFxxxxT lunokubonelela abasebenzisi ngezisombululo zokusasaza imiqondiso ekude ezinokuthenjwa, eziguquguqukayo, nezichasene kakhulu nokuphazamiseka.
Inkcazelo yeMveliso yeRF phezu kwefayibha
Uthotho lwe-R-ROFxxxxTIkhonkco le-RF phezu kwefayibhaIkhonkco le-transceiver ye-analog broadband optical sisixhobo sokudlulisa kude se-fiber optic esenzelwe ngokukodwa ukulinganisa imiqondiso yombane ye-DC ukuya kwi-1GHz ngexesha langempela kwiindawo ezintsonkothileyo ze-electromagnetic. Imodyuli yokudlulisa ine-1 MΩ/50 Ω BNC input, enokunxibelelana nezixhobo ezahlukeneyo zokuva (iiprobe zangoku, iiprobe ze-high-voltage okanye izixhobo ezithile zokulinganisa i-high-frequency). Kwimodyuli yokudlulisa, isignali yombane yokufaka iyaguqulwa kwaye iguqulwe ibe yisignali ye-optical, emva koko ithunyelwa kwimodyuli yokufumana ngefayibha ye-optical yemo enye. Imodyuli yokwamkela iguqula isignali ye-optical ibuye ibe yisignali yombane. Ukudluliselwa kwesignali ye-optical kulawulwa lulawulo lwenqanaba oluzenzekelayo ukugcina ukusebenza ngokuchanekileyo nangokuqhubekayo, kungachaphazeleki kukulahleka kokukhanya. Zombini iimodyuli ze-transceiver zixhasa umbane webhetri kunye nolawulo olukude. Imodyuli yokudlulisa okubonakalayo ikwabandakanya i-attenuator ehlengahlengiswayo eguquguqukayo (1:1/10:1/100:1) yokulungisa inqanaba lesignali efunyenweyo ukuze kuphuculwe uluhlu oluguquguqukayo. Ukongeza, xa isixhobo singasetyenziswa, sinokufakwa kude kwimodi yokulinda yamandla aphantsi ukuze kongiwe amandla ebhetri, kwaye isibane se-LED sibonisa imeko yokusebenza.
