This optical receiver module is designed for radio and TV broadcasting applications. 1 While each RX Series model is designed and intended for operation over the specified wavelength range shown by the solid colored regions, each will respond with reduced performance to optical inputs at shorter wavelengths, as shown by the partially transparent regions. Our engineers and. This is our latest high-end two-way output CATV network Fiber Optics Receiver. The L-RF-19R-RX is used to convert a fiber optic connection to RF (coax output). Full software functionality is included for high-performance reception of AM, FM, and DRM (DRM30 and DRM+) broadcasts worldwide, across MF, HF. The 7830W CATV optical receiver is a single-mode fiber pigtailed module featuring a low-noise, impedance-matched broadband photodiode and RF amplification.
