Overview
This system uses optical methods to transmit RF signals. It converts analog RF signals received by HF antennas into optical signals through photoelectric conversion, modulating them onto a laser for long-distance, low-loss transmission.
The system offers significant advantages: long transmission distance, wide dynamic range, strong immunity to EMI, high confidentiality, and flexible deployment. It effectively resolves site selection constraints caused by coaxial cables being prone to EMI, limited transmission distance, and high signal loss. As such, it is a modern key approach for high‑quality, long‑distance signal transmission between the antenna field and the control center of an HF receiving station.
