Amathuba Amatsha kuNxibelelwano lweMicrowave: 40GHz Analog LinkI-RF ngaphezulu kwefayibha
Kwicandelo lonxibelelwano lwe-microwave, izisombululo zothumelo lwemveli bezisoloko zithintelwe ziingxaki ezimbini ezinkulu: iintambo ze-coaxial ezibizayo kunye ne-waveguides azinyusi nje iindleko zokusasazwa kodwa zikwanciphisa kakhulu uthumelo lwesignali ngomgama. Ngaphezu koko, ukugubungela ibhendi yefrikhwensi kunye nozinzo kunzima ukuhlangabezana neemfuno zezicelo ze-broadband. Sijongene nale meko, sinelunda ukunicebisa - uthotho lwe-ROFBox 40GHz lwangaphandle lweModulation Broadband Analog Link RF phezu kwefayibha. Le ayisiyomveliso nje kuphela; liphepha leempendulo elibalaseleyo esilithumele ukuze sidlule kwimida yomzimba.
Le mveliso intsha isebenzisa isisombululo sokudlulisa i-optical transmission sangaphandle, esixhasa ukuguqulwa kwesignali ze-RF ngaphandle kokulahlekelwa ngaphakathi koluhlu olubanzi lwe-1-40GHz ultra-wideband. Ithatha indawo yemidiya yesinyithi yendabuko ngeamakhonkco efayibha ye-optical, iphula ngokupheleleyo imida ebonakalayo yomgama wokudluliselwa. Inzuzo yayo ephambili iku:
Ukuthembeka okuphezulu kwebhendi epheleleyo: Ukugubungela i-wideband ye-1-40GHz, kudityaniswe noyilo olucwangcisiweyo, kuqinisekisa ukuveliswa kwakhona ngokuchanekileyo kobukhulu besiginali kunye nesigaba. Ukunyuka kwexabiso elifanelekileyo: Ziphephe iintambo ze-coaxial ezibizayo kunye neendibano ze-waveguide, kunciphisa iindleko zokusasazwa ngaphezulu kwe-60%; Ukuphumelela kubuchule bokulwa nokuphazamiseka:Ukuhanjiswa kwefayibha ye-Opticalayimelani ngokwemvelo nokuphazamiseka kwe-electromagnetic, kwaye uzinzo lwesignali kwiindawo ezintsonkothileyo luphuculwe kakhulu.
Ukusuka ekudlulisweni kwesignali kunxibelelwano olungenazingcingo olukude ukuya ekwabiweni ngokuchanekileyo kwezibonakaliso zesalathiso sexesha, kuze kube kukusetyenziswa okusebenzayo kweenkqubo zetelemetry kunye nemigca yokulibaziseka, inokukwazi ukuzivumelanisa ngokuchanekileyo, inike inkxaso enamandla kwiimeko ezahlukeneyo ze-microwave ye-broadband kwaye ivule imida enokwenzeka yokuchaza ngokutsha usetyenziso lwe-microwave ye-analog broadband.
Ingcaciso yeMveliso
Uthotho lwe-ROFBox lwe-broadband yokuguquguquka kwangaphandleIkhonkco le-Analog RF phezu kwefayibhaIsebenzisa indlela yokusebenza yemodulation yangaphandle kwaye inokubonelela ngokudluliselwa kwemiqondiso ye-RF ngaphakathi koluhlu lwefrikhwensi ye-1-40GHz, inikezela ngonxibelelwano lwefayibha ye-optical olusebenza kakuhle kakhulu kwii-microphone ezahlukeneyo ze-analog broadband. Ngokuphepha ukusebenzisa iintambo ze-coaxial ezibizayo okanye ii-waveguides, umda womgama wokudluliselwa uye wasuswa, nto leyo ephucula kakhulu umgangatho wesignali kunye nokuthembeka konxibelelwano lwe-microwave. Ingasetyenziswa ngokubanzi kwiindawo zonxibelelwano lwe-microwave ezifana ne-remote wireless, i-timing, i-reference signal distribution, i-telemetry kunye ne-delay lines.
