Heavy-lift High Power optical fiber tethered drone system

This product is a high-performance tethered drone system using optical fiber, designed for long-duration, heavy-duty flight missions. The system supports flight altitudes of over 100 meters, and even up to 200 meters, and can carry weights of 20 to 30Kg. With tethered power supply, it enables continuous flight for over 24 hours, making it suitable for various demanding environments and mission requirements. The heavy-duty optical fiber tether system is an advanced integration of drone technology and optical fiber communication technology, enabling long-duration hovering in the air while transmitting high-speed, high-bandwidth data signals via optical fiber. This ensures stable and interference-free video signal transmission from the sky to the ground, guaranteeing safe and stable long-term aerial monitoring.
