Product Introduction
Our company's KY-FOL series RF optical fiber module is a miniaturized high-performance optical module with a very wide dynamic range specially designed for the transmission of 100M-3GHz RF signals through optical fiber. The emission part is a direct modulation high linearity DFB laser, the working wavelength is 1310 or 1550nm, the external automatic power control (AAPC) circuit ensures the best optical power and stable optical wavelength in the whole operating temperature range, and the module gain can be adjusted, which can be applied to a variety of application directions, such as GPS antenna remote, time-frequency signal transmission, L-band satellite communication, etc.
