Zatsopano Zatsopano mu Microwave Communication :40GHz Analog LinkRF pa fiber

Pankhani ya kuyankhulana kwa ma microwave, njira zotumizira anthu nthawi zonse zakhala zikulepheretsedwa ndi zovuta ziwiri zazikulu: zingwe zokwera mtengo za coaxial ndi ma waveguide samangowonjezera ndalama zotumizira komanso amachepetsa kufalikira kwa ma sign patali. Kuphatikiza apo, kufalikira kwa ma frequency band ndi kukhazikika kumakhala kovuta kukwaniritsa zofunikira zamapulogalamu amtundu wa Broadband. Poyang'anizana ndi izi, ndife olemekezeka kukupangirani - ROFBox mndandanda wa 40GHz kunja Modulation Broadband Analog Link RF pa fiber. Izi sizinthu chabe; ndi mayankho omwe tapereka kuti tithane ndi zofooka zathupi.

Chogulitsa chatsopanochi chimagwiritsa ntchito njira yosinthira yakunja, yothandizira kutembenuka kopanda kutaya kwa ma siginecha a RF mkati mwamitundu yambiri ya 1-40GHz Ultra-wideband. Iwo m'malo chikhalidwe zitsulo TV ndimawonekedwe a fiber optic, kuphwanya kwathunthu zofooka zakuthupi za mtunda wopatsirana. Ubwino wake waukulu uli mu:

Kukhulupirika kwakukulu kwa gulu lonse: Kufalikira kwa 1-40GHz wideband, kuphatikizidwa ndi mapangidwe okongoletsedwa ndi mizere, kumatsimikizira kutulutsa kolondola kwa matalikidwe a siginecha ndi gawo. Kudumpha kwamitengo: Pewani zingwe zokwera mtengo za coaxial ndi ma waveguide, kuchepetsa ndalama zotumizira ndi 60%; Kupambana pakutha kwa anti-interference:Kutumiza kwa fiber opticmwachilengedwe imagonjetsedwa ndi kusokonezedwa ndi ma electromagnetic, ndipo kukhazikika kwa chizindikiro m'malo ovuta kwasintha kwambiri.

Kuchokera pamawu olumikizirana pamalumikizidwe akutali opanda zingwe mpaka kugawika kolondola kwa ma siginecha anthawi, kenako kugwiritsa ntchito makina a telemetry ndi mizere yochedwa, imatha kusinthiratu, kupereka chithandizo champhamvu pamitundu yosiyanasiyana ya ma microwave ndikutsegula malire omwe angathe kutanthauziranso ntchito za analogi Broadband microwave.

Mafotokozedwe Akatundu

Mndandanda wa ROFBox wa Broadband yosinthira kunjaAnalogi Link RF pa CHIKWANGWANIimatengera mawonekedwe akunja ogwirira ntchito ndipo imatha kutumizira ma siginecha a RF mkati mwa ma frequency a 1-40GHz, yopereka kulumikizana kwapamwamba kwambiri kwa liniya wa fiber fiber pamitundu yosiyanasiyana ya ma analogi ma microwave. Popewa kugwiritsa ntchito zingwe zokwera mtengo za coaxial kapena ma waveguide, kuchepetsa mtunda wa kufalikira kwathetsedwa, kuwongolera kwambiri mawonekedwe azizindikiro ndi kudalirika kwa kulumikizana kwa ma microwave. Itha kugwiritsidwa ntchito kwambiri m'magawo olankhulirana a microwave monga opanda zingwe zakutali, nthawi, kugawa kwazizindikiro, telemetry ndi mizere yochedwa.
