UAV optical cables (fiber-optic guidance technology) show the following core advantages in battlefield applications:
1. Strong anti-interference ability
Fiber-optic cables transmit optical signals through closed physical channels, which are completely unaffected by electromagnetic interference and electronic warfare, and can still operate stably in complex electromagnetic environments.
Compared with the characteristics of traditional radio signals that are easily detected and interfered with, fiber-optic communication avoids the problem of RF signal leakage and significantly improves battlefield survivability.
2. Stable and high-quality signal transmission
It has high bandwidth and low latency characteristics, and supports real-time transmission of high-definition images (such as millimeter-level control through VR glasses).
Low transmission loss, signal stability can be maintained at a distance of 10 kilometers (the fiber length of some models can reach 41.4 kilometers).
3. Ultra-long-distance precision strikes
The Russian "Prince Vandal" drone achieves target number-level precision strikes through 20 kilometers of optical fiber. The Ukrainian model has set a world record of 41.4 kilometers of optical fiber guidance.
With real-time control by ground operators, it can perform "room search-style" hunting missions within a range of 10 kilometers.
4. Tactical flexibility and economy
The cost of a single machine is as low as $500, and it supports complex tactical actions such as tracking moving targets (such as tanks) and penetrating buildings.
It adopts modular design, is compatible with civilian fiber optic protocols, and can be quickly assembled and deployed.
5. Outstanding physical concealment
The diameter of the optical fiber is generally less than 0.5 mm, and the weight is extremely light (such as the 0.45 mm diameter model), which does not affect the maneuverability of the drone.
It does not radiate signals to the outside, greatly reducing the probability of being detected by radar/infrared.
6. Security guarantee
The closed optical signal transmission is difficult to be intercepted or deciphered, and a complete confidential link can be built with a two-way encryption protocol.
Some models also realize power transmission through optical fiber, breaking through the battery life limit.
