Chingwe cha Rof analog broadband optical transceiver RF Over Fiber

Chingwe cha R-ROFxxxxT cha RF over fiber Link analog broadband optical transceiver link ndi chipangizo chotumizira mauthenga chakutali cha fiber optic chomwe chapangidwira kuyeza nthawi yeniyeni zizindikiro zamagetsi za DC mpaka 1GHz m'malo ovuta amagetsi. Module yotumizira ili ndi 1 MΩ/50 Ω BNC input, yomwe imatha kulumikizidwa ku zipangizo zosiyanasiyana zozindikira (ma probe amakono, ma probe amphamvu kwambiri kapena zipangizo zinazake zoyezera maulendo apamwamba). Mu module yotumizira, chizindikiro chamagetsi cholowera chimasinthidwa ndikusinthidwa kukhala chizindikiro cha kuwala, chomwe chimatumizidwa ku module yolandira kudzera mu ulusi wa kuwala wa single-mode. Module yolandira imasandutsa chizindikiro cha kuwala kubwerera kukhala chizindikiro chamagetsi. Kutumiza kwa chizindikiro cha kuwala kumayendetsedwa ndi kulamulira kwa mlingo wokha kuti kukhale ndi magwiridwe antchito olondola komanso okhazikika, osakhudzidwa ndi kutayika kwa kuwala. Ma module onse a transceiver amathandizira magetsi a batri ndi kulamulira kwakutali. Module yotumizira mauthenga a kuwala imaphatikizaponso attenuator yosinthika yosinthika (1:1/10:1/100:1) yosinthira mulingo wa chizindikiro cholandiridwa kuti chikwaniritse bwino mphamvu zamagetsi. Kuphatikiza apo, chipangizocho chikapanda kugwiritsidwa ntchito, chikhoza kulowetsedwa kutali mu mode yoyimirira yamphamvu yochepa kuti batri lisunge mphamvu, ndipo kuwala kwa LED kumawonetsa momwe ntchito ikuyendera.
