IntshaRF phezu kwefayibhaisisombululo
Kwimeko yanamhlanje entsonkothileyo ye-electromagnetic kunye nokuvela okuqhubekayo kokuphazamiseka kweempawu, indlela yokufezekisa ukuthembeka okuphezulu, umgama omde kunye nokuhanjiswa okuzinzileyo kwemiqondiso yombane ebanzi ibe ngumngeni ophambili kwinkalo yokulinganisa kunye novavanyo lwamashishini. Ikhonkco le-RF phezu kwefayibha ye-analog ye-transceiver optical transceiver yinto entsha kanyeukuhanjiswa kwefiber opticalisisombululo esenzelwe ukujongana nalo mngeni.
Esi sixhobo sixhasa ukuqokelela kwexesha langempela kunye nokuhanjiswa kwezibonakaliso ze-wideband ukusuka kwi-DC ukuya kwi-1GHz, kwaye inokuguqulwa ngokuguquguqukayo kwizixhobo ezahlukeneyo zokubona, kubandakanywa iiprobes zangoku, i-high-voltage probes kunye nezinye izixhobo zokulinganisa i-frequency ephezulu. Isiphelo saso sokuhambisa sixhotyiswe nge-1 MΩ/50 Ω i-interface etshintshayo ye-BNC yokufaka, ebonisa ukuhambelana okubanzi. Ngethuba lokucwangcisa umqondiso, izibonakaliso zombane ziguqulwa kwaye ziguqulelwe kwiimpawu ze-optical, ezithi zidluliselwe ekupheleni kokufumana nge-fiber optical mode enye kwaye zibuyiselwe ngokuchanekileyo kwiimpawu zombane zangaphambili ngemodyuli yokufumana.
Kuyafaneleka ukukhankanya ukuba uchungechunge lwe-R-ROFxxxxT ludibanisa indlela yokulawula inqanaba elizenzekelayo (i-ALC), enokuthi ithintele ngokufanelekileyo ukuguquguquka kwezibonakaliso ezibangelwa ukulahleka kwefayibha kunye nokuqinisekisa ukusebenza rhoqo ngexesha lokuhanjiswa kwexesha elide. Ukongeza, imodyuli yothumelo ixhotyiswe nge-attenuator eguquguqukayo kunye ne-adjustable, exhasa uhlengahlengiso olunamandla lwe-1: 1/10: 1/100:1. Oku kuvumela abasebenzisi ukuba baphucule inqanaba lokwamkela umqondiso ngokusekelwe kwimiba yokwenyani kunye nokwandisa uluhlu oluguquguqukayo lwenkqubo.
Ukuhlangabezana neemfuno zentsimi okanye uvavanyo lweselula, olu luhlu lweemodyuli luxhasa unikezelo lwamandla ebhetri kunye nolawulo olukude, kwaye lubonisa imowudi yokulinda ekrelekrele engena ngokuzenzekelayo kwimeko yamandla aphantsi ngexesha elingasetyenziswanga, ukwandisa ngokufanelekileyo ubomi bebhetri yesixhobo. Izibane ze-LED kwiphaneli yangaphambili zibonelela ngengxelo yexesha langempela malunga nesimo sokusebenza, ngakumbi ukuphucula ukusebenza kunye nokusebenza kwezixhobo.
Nokuba kwiimeko ezinje ngokujongwa kwamandla, ukuvavanywa kwamaza kanomathotholo, okanye imifuniselo yophando lwezenzululwazi, uthotho lwe-R-ROFxxxxT lunokubonelela abasebenzisi ngezisombululo ezithembekileyo, eziguquguqukayo, nezichasene nophazamiseko olukude.
I-RF phezu kwefayibha Inkcazo yeMveliso
Uluhlu lwe-R-ROFxxxxTRF phezu ifayibha LinkIkhonkco le-analog Broadband optical transceiver sisixhobo sokuhambisa i-fiber optic esikude esilungiselelwe ngokukodwa ukulinganisa ixesha lokwenyani le-DC ukuya kwi-1GHz imiqondiso yombane kwiindawo ezinzima ze-electromagnetic. Imodyuli yokudlulisa ifaka i-1 MΩ/50 Ω igalelo le-BNC, elinokuthi lidityaniswe nezixhobo ezahlukeneyo zokuva (i-probes yangoku, iiprobes eziphezulu-voltage okanye izixhobo ezithile zokulinganisa i-high-frequency). Kwimodyuli yokudlulisa, igalelo lombane lombane liguqulwa kwaye liguqulelwe kwisignali ye-optical, ethi ke ithunyelwe kwimodyuli yokufumana i-fiber optical mode enye. Imodyuli yomamkeli iguqula isignali ye-optical ibuyele kwisignali yombane. Ukuhanjiswa kwesignali ye-optical ilawulwa ngulawulo lwezinga elizenzekelayo ukuze kugcinwe ukusebenza okuchanekileyo kunye nokuqhubekayo, okungachaphazeli ukulahleka kwe-optical. Zombini iimodyuli ze-transceiver zixhasa unikezelo lwamandla ebhetri kunye nolawulo olukude. Imodyuli yokuhanjiswa kwe-optical iquka i-attenuator eguquguqukayo eguquguqukayo (1: 1 / 10: 1 / 100: 1) yokulungelelanisa inqanaba lesignali efunyenweyo ukuze kulungiswe uluhlu oluguquguqukayo. Ukongeza, xa isixhobo singasetyenziswanga, sinokungeniswa ukude kwimowudi yokulinda yamandla aphantsi ukugcina amandla ebhetri, kwaye ukukhanya kwesalathisi se-LED kubonisa isimo sokusebenza.
