Optical fibers, known for their immunity to electromagnetic interference, present a promising alternative to coaxial cables for long-range signal transmission in radio telescopes. This study introduces a cost-effective solution for analog signal transmission over fiber, specifically designed for radio astronomy applications. By modifying Small Form-factor Pluggable (SFP) modules, we developed a dual-channel Radio-over-Fiber (RFoF) system with a total cost under $100 USD. Our measurements indicate that the system meets the performance requirements of most radio telescope configurations and has reached technology readiness level 6. This manuscript details the design, modifications, and testing of the SFP modules, showcasing their potential benefits for radio astronomy.
