Optical communication UAV wiring harness system
Optical communication UAV harness system components
Optical fiber harness
Using single-mode optical fiber (core diameter 8-10μm, total diameter ≤0.25mm) as the transmission medium, the UAV flight control, sensors and mission equipment are connected through the bus architecture, supporting 5-20 km dynamic release, and maintaining stable transmission at a flight speed of 120km/h.
Harness protection: The outer layer uses an anti-vibration carbon fiber shell, integrated with epoxy resin sealing technology, and can withstand extreme temperatures from -40℃ to 125℃.
Photoelectric conversion module
The airborne end is equipped with LD light source and variable focus fiber collimator, and the ground end is deployed with MPPC array receiver to achieve bidirectional conversion of electrical and optical signals, with bandwidth up to TB/s and delay less than 1ms.
Power supply integrated design
80A high current power supply and data signal are transmitted synchronously through the optical fiber bus cascade architecture, reducing the number of cables and optimizing the UAV load distribution.
