IntshaI-RF phezu kwe-fiberisisombululo
Esimweni sanamuhla esiyinkimbinkimbi ye-electromagnetic kanye nokuvela okuqhubekayo kokuphazamiseka kwesignali, indlela yokufinyelela ukuthembeka okuphezulu, ibanga elide kanye nokudluliselwa okuzinzile kwamasignali kagesi we-wideband kuye kwaba inselele enkulu emkhakheni wokulinganisa nokuhlola kwezimboni. Isixhumanisi se-RF phezu kwe-fiber analog broadband optical transceiver siyinto entsha impelaukudluliswa kwe-fiber opticalisixazululo esiklanyelwe ukubhekana nale nselelo.
Le divayisi isekela ukuqoqwa kwesikhathi sangempela kanye nokudluliswa kwamasignali e-wideband kusuka ku-DC kuya ku-1GHz, futhi ingashintshwa kalula kumadivayisi okubona ahlukahlukene, okuhlanganisa ama-probe amanje, ama-high-voltage probe namanye amathuluzi okulinganisa amafrikhwensi aphezulu. Isiphetho sayo sokudlulisa sifakwe isixhumi esibonakalayo se-BNC esishintshekayo esingu-1 MΩ/50 Ω, esihambisana nokuhambisana okubanzi. Ngesikhathi sokucutshungulwa kwesignali, amasignali kagesi ayashintshwa futhi aguqulwe abe amasignali optical, abese edluliselwa endaweni eyamukelayo nge-single-mode optical fibers futhi abuyiselwe ngokuqondile kumasignali kagesi okuqala ngemojula eyamukelayo.
Kuhle ukusho ukuthi uchungechunge lwe-R-ROFxxxxT luhlanganisa indlela yokulawula izinga elizenzakalelayo (i-ALC), engamelana ngokuphumelelayo nokuguquguquka kwesignali okubangelwa ukulahlekelwa kwefayibha futhi iqinisekise ukusebenza okuqhubekayo phakathi nokudluliswa kwebanga elide. Ukwengeza, imojula yokudlulisela ifakwe i-attenuator eguquguqukayo futhi eguquguqukayo, esekela ukulungiswa okunamandla oku-1:1/10:1/100:1. Lokhu kuvumela abasebenzisi ukuthi bathuthukise izinga lokwamukela isignali ngokusekelwe kuzimo zangempela futhi banwebe ububanzi obuguqukayo besistimu.
Ukuze kuhlangatshezwane nezidingo zenkambu noma ukuhlola kweselula, lolu chungechunge lwamamojula lusekela ukunikezwa kwamandla ebhethri nesilawuli kude, futhi lufaka imodi yokulinda ehlakaniphile engena ngokuzenzakalelayo kusimo samandla aphansi phakathi nezikhathi zokungasebenzisi, okunweba ngempumelelo impilo yebhethri yedivayisi. Izibani zezinkomba ze-LED kuphaneli yangaphambili zinikeza impendulo yesikhathi sangempela mayelana nesimo sokusebenza, okuqhubeka kuthuthukisa ukusebenza nokusebenza kwesisetshenziswa.
Kungakhathaliseki ukuthi kuzimo ezifana nokuqapha amandla, ukuhlolwa kwefrikhwensi yerediyo, noma ukuhlolwa kocwaningo lwesayensi, uchungechunge lwe-R-ROFxxxxT lunganikeza abasebenzisi izixazululo ezinokwethenjelwa, eziguquguqukayo, neziphikisana kakhulu nokuphazamiseka okukhulu kwesignali yokudlulisa.
Incazelo yomkhiqizo we-RF phezu kwefayibha
Uchungechunge lwe-R-ROFxxxxTI-RF phezu kwe-fiber LinkIsixhumanisi se-analog broadband optical transceiver iyisisetshenziswa se-fiber optic esikude esiklanyelwe ukukala isikhathi sangempela se-DC kuya ku-1GHz amasiginali kagesi ezindaweni eziyinkimbinkimbi zikazibuthe. Imojula yokudlulisa ifaka okokufaka okungu-1 MΩ/50 Ω BNC, okungaxhunywa kumadivayisi ahlukahlukene ezinzwa (ama-probe amanje, ama-high-voltage probe noma amadivaysi athile okulinganisa amafrikhwensi aphezulu). Kumojula yokudlulisa, isignali kagesi yokufaka iyashintshwa futhi iguqulwe ibe isignali ye-optical, ebese ithunyelwa kumojula eyamukelayo nge-fiber optical yemodi eyodwa. Imojula yokwamukela iguqula isignali yokubona ibuyele kusignali kagesi. Ukudluliswa kwesignali ye-optical kulawulwa ukulawulwa kwezinga elizenzakalelayo ukuze kugcinwe ukusebenza okunembile nokuqhubekayo, okungathinteki ukulahlekelwa kwe-optical. Womabili amamojula we-transceiver asekela ukunikezwa kwamandla ebhethri nesilawuli kude. Imojula yokudlulisa amehlo iphinde ihlanganise nesibaliseli esiguquguqukayo esiguqukayo (1:1/10:1/100:1) sokulungisa ileveli yesiginali eyamukelwe ukuze kwandiswe ububanzi obuguquguqukayo. Ngaphezu kwalokho, uma idivayisi ingasetshenziswa, ingafakwa ukude kumodi yokulinda yamandla amancane ukuze wonge amandla ebhethri, futhi isibani se-LED sibonisa isimo sokusebenza.
Izici zomkhiqizo
Umkhawulokudonsa we-DC-500 MHZ/DC-1 GHZ uyazikhethela
Isinxephezelo sokulahlekelwa kokufakwa kwe-adaptive
Inzuzo iyalungiseka futhi ububanzi bokufakwayo obuguqukayo buthuthukisiwe
Isekela isilawuli kude futhi inamandla ebhethri, ikwenze kube lula ukusetshenziswa ngaphandle
