The advantages of using optical fiber to transmit data in UAVs include strong anti-interference ability, high safety, large and stable transmission bandwidth, while the disadvantages include fiber weight affecting load, complex release mechanism, limited endurance, high cost and easy to find and destroy. The following is a detailed analysis of these advantages and disadvantages:
Advantages

Strong anti-interference ability: optical fiber communication is not affected by electromagnetic interference, and can stably transmit data in a strong electromagnetic suppression environment. This allows the UAV to maintain efficient communication capabilities in a complex electromagnetic battlefield environment, avoiding the problem that traditional radio communications are susceptible to interference.

High security: optical fiber communication can not be wireless eavesdropping, and the physical isolation characteristics of optical fiber to eliminate the risk of signal leakage, so that the UAV has excellent concealment. This helps UAVs maintain a high degree of security when performing reconnaissance, strike and other tasks.

The transmission bandwidth is large and stable: the transmission bandwidth of optical fiber can reach TB level, which is more than 1000 times that of 5G network, which is enough to support real-time return of massive data such as 8K video and lidar point cloud. At the same time, optical fiber communication can still maintain extremely low signal loss and delay in long-distance transmission, ensuring the stability and real-time of data transmission.

Energy supply potential: Some fiber-optic drones transmit data and electricity simultaneously through optical fiber (Power over Fiber technology) to achieve "unlimited endurance". This technology provides a longer-lasting energy supply for UAVs and prolongs the combat time of UAVs.

The weight of the fiber affects the load: The weight of the fiber optic cable will significantly increase the load of the drone, affecting the flight performance and endurance of the drone. For example, taking a 0.5mm diameter optical fiber as an example, when paired with carbon fiber and aluminum alloy shell, its combined weight may exceed 2kg, which limits the payload and flight distance of the UAV.

The release mechanism is complex: the fiber optic release mechanism requires the UAV to maintain a high degree of consistency with the ground communication, limiting its flexibility. In complex terrain or long-term flight, optical fiber may lead to communication interruption or UAV out of control due to winding, fracture and other factors.

Limited endurance: Although the data itself does not consume electricity, the weight of the fiber optic cable and the limitation of the release mechanism will still affect the endurance of the drone. In addition, drones that partially rely on optical fiber to transmit power may also have limitations in power transmission efficiency.

High cost: The manufacturing cost of fiber-optic drones is relatively high, including the manufacturing and integration costs of precision components such as fiber-optic cables, photoelectric converters, and reels. This makes fiber-optic drones face certain economic pressure in mass production and application.

Easy to be found and destroyed: Optical fibers reflect visible light under certain lighting conditions and are easily found by the enemy. In addition, fiber optic cables are easy to be hung up or twisted in complex terrain, and the probability of accidents increases with the increase of length. These factors increase the risk of fiber-optic UAVs in actual combat.
