8.Cable Introduction
Unmanned aerial vehicle (UAV) optical fiber technology refers to the integration of optical fibers with UAV systems, leveraging their high-speed, stable and anti-interference characteristics to enhance the communication, navigation and sensing capabilities of UAVs. By means of optical fiber as transmission medium, the optical signal for data transmission. Specifically, the video signals captured by the cameras on the unmanned aerial vehicle are first converted into optical signals and then transmitted to the ground via optical fibers. At the ground end, the optical signal is then converted back into an electrical signal and decoded into a video signal to be displayed on the screen. This process is based on the total internal reflection phenomenon of light. The optical signal is transmitted within the core of the optical fiber and is protected by an external optical fiber shell to ensure that the optical signal does not leak or be interfered with during transmission.
9.Advantages
1. High-speed data transmission
2. Strong anti-interference ability
3. High security
