Ma module a ROF RF a Broadband Transceiver Module RF over fiber link Analog broadband RoF link
Chingwe cha analog RoF (ma module a RF) chimapangidwa makamaka ndi ma module otumizira ma analog optical ndi ma module olandirira ma analog optical, zomwe zimapangitsa kuti ma signal a RF afalikire mtunda wautali mu ulusi wa optical. Mapeto otumizira amasintha chizindikiro cha RF kukhala chizindikiro cha optical, chomwe chimatumizidwa kudzera mu ulusi wa optical, kenako gawo lolandira limasintha chizindikiro cha optical kukhala chizindikiro cha RF. Ma RF fiber optic transmission link ali ndi makhalidwe monga kutayika kochepa, broadband, large dynamic, ndi chitetezo ndi chinsinsi, ndipo amagwiritsidwa ntchito kwambiri mu ma antenna akutali, kulumikizana kwa analog fiber optic mtunda wautali, kutsatira, telemetry ndi kuwongolera, mizere yochedwa ya microwave, malo osungira ma satellite, radar, ndi madera ena. Conquer yayambitsa mndandanda wazinthu zotumizira ma fiber optic a RF makamaka pamunda wotumizira ma RF, zomwe zimaphatikizapo ma frequency band angapo monga L, S, X, Ku, ndi zina zotero. Imagwiritsa ntchito chipolopolo chachitsulo chopopera chokhala ndi kukana bwino kwa electromagnetic interference, gulu logwira ntchito lonse, komanso kusalala bwino mkati mwa gululo.
