Product Description

Product Background

Advances in optical fiber communication technology: Optical fibers have the advantages of large communication capacity, long relay distance, and strong anti-interference ability. With the development of technology, the loss of optical fibers has been continuously reduced, and the transmission performance has been continuously improved. Long-distance optical fiber communication has become a reality. To meet the needs of different long-distance communication scenarios, such as inter-city backbone network connections and communication coverage in remote areas, different lengths and specifications of optical fibers are required, which has led to the emergence of corresponding length optical fiber tubes. These tubes are used to store and protect the optical fibers, making it convenient for the laying and use of the optical fibers.
Expansion of drone applications: Traditional drones rely on wireless signal transmission for data and control. In complex electromagnetic environments, the signals are easily interfered with, and the transmission distance is limited. After the optical fiber tubes are applied to drones, they can establish communication links with the ground by releasing optical fibers. The optical signals are basically not affected by external electromagnetic interference within the optical fibers, ensuring stable data transmission. According to the different operational requirements and scenarios of drones, different lengths of optical fiber tubes are needed. For example, in some short-distance urban pipeline inspection and indoor inspection scenarios, 3 kilometers or 5 kilometers of optical fiber tubes can meet the requirements; while in scenarios that require a longer operational distance, such as marine monitoring and border area patrol, 10 kilometers or even 20 kilometers of optical fiber tubes will be used.

Military domain requirements: In the military field, fiber-optic guided unmanned aerial vehicles have been widely applied. The fiber-optic guidance system consists of a guidance head and a bidirectional fiber-optic transmission system. Fiber optics have advantages such as small diameter, light weight, and resistance to interference, which significantly improve upon the traditional metal wire guidance method. In the Ukraine-Russia battlefield, various fiber-optic unmanned aerial vehicles have been deployed, with fiber lengths ranging from 5 kilometers to 20 kilometers. For instance, the Russian "Vandal Prince" unmanned aerial vehicle has a fiber length of 18 - 20 kilometers, capable of carrying ammunition to perform navigation, search, and attack missions. This determines their combat radius and mission execution scope.
Special scenario monitoring needs: In some scenarios requiring remote monitoring, such as the monitoring of important facilities, and the monitoring of disaster sites like earthquakes and fires, there are high requirements for the stability and clarity of video transmission. Traditional wireless monitoring is prone to signal attenuation and picture lag when transmitting over long distances. However, fiber-optic remote monitoring can utilize the high-speed and high-bandwidth characteristics of fiber optics to achieve long-distance, high-definition, and stable video transmission. Different monitoring scenarios require corresponding lengths of fiber optic tubes to lay fiber optic lines. For example, in monitoring scenarios with relatively small areas such as large parks and reservoirs, a 3 - 5 kilometer fiber optic tube may be sufficient, while for large-scale infrastructure monitoring across regions, a fiber optic tube of 10 kilometers or more may be required.

Communication Experiments and New Technology Development: With the continuous innovation of optical communication technology, new transmission technologies and concepts are constantly emerging. For instance, the global first 800G hollow-core optical fiber transmission technology trial network launched by Shenzhen Mobile has achieved multiple core technical indicators on a 20-kilometer link, reaching international leading levels. In such communication experiments, different lengths of optical fibers are needed to verify the performance of the technology at different distances. Optical fiber tubes provide excellent storage and protection for the optical fibers, facilitating the conduct of the experiments.
