At the beginning of the realization of optical fiber communication technology, it has received great attention from all walks of life, especially in the military field. With the development of the times, optical fiber technology has been perfectly integrated with the military field and its status is getting higher and higher. Most of the equipment used fiber optic technology, which greatly improved the military combat effectiveness of the US military and promoted the development of the military field.
- Tactical communications application
Optical fiber communication has been widely used in the military fields of countries all over the world through the use of light waves as carriers and transmission media as optical fibers. The traditional military communication technology does not meet the needs of modern military development. The application of fiber-optic communication technology in military communications can adapt to various complex environmental conditions and greatly enhance the command and combat capability of the military.
In modern military warfare, the quality of communication technology often affects the changes in the situation of war. Therefore, there are strict requirements on the quality and efficiency of communication technology. First, military communication technology is different from civilian communication technology. The civilian communication network is relatively large, and the military communication network is smaller and more targeted. Therefore, in network construction, it is usually a wireless communication method based on optical fiber communication. In the transmission and transmission of signals, multi-band, multi-method and multi-line communication methods are adopted, which are more targeted and accurate in signal transmission and transmission. And confidentiality is better. Secondly, due to the small signal interference and strong anti-electromagnetic interference of fiber-optic communication, it can adapt to various complex battlefield environments and can complete signal transmission with high quality, which is conducive to gaining war advantage. Finally, fiber-optic communication is small in size and relatively mobile, and can be effectively applied to machinery and equipment, which is conducive to the construction of the battlefield command, avoiding the distance limitation of traditional cable laying and the trouble of cable connection.
2. Application in navy
In modern naval battles, underwater anti-submarine missions are particularly important. By detecting the trajectory of underwater submersibles and accurately finding the position of the submarine, it is very important both in offensive and defensive. The specific workflow is to establish an Underwater anti-submarine network system, real-time monitoring of underwater, mainly consists of three parts including hydrophone, fiber transmission cable and data processing center. The signal of the submarine is transmitted to the command center through the optical fiber line by the hydrophone, and the data information is analyzed to determine the position and heading of the submarine, and the operational plan is determined according to the actual situation.
Then, the use of fiber-optic communication technology to complete the cleaning of mines, mainly by the minesweeper and the floating carrier to establish a two-way transmission of fiber-optic communications, through the floating carrier to collect and transmit signals to complete the mine detection, and thus clean.
3. Application on the Army
(1) Application in optical fiber guidance
Missiles and torpedoes are two of the main aspects of fiber-guided weapons. The principle of optical fiber guidance is similar to the traditional remote control method. The main difference is that fiber optic interface, photoelectric converter and optical fiber line are used on the weapon to form artificial intelligence weapon. The target image is transmitted to the control in real time by using fiber optic technology communication. Personnel, this type of operation is highly accurate, greatly improving the range of the missile and achieving high-quality combat missions.
(2) Application on radar
The use of fiber-optic communication technology on military radar can effectively improve the anti-interference ability of radar and terminal equipment, avoid the leakage of data during transmission, and also contribute to the security of the information center. The traditional radar antenna is relatively large. The concealment is not strong, it is easy to be discovered by the enemy, and some means of attack are taken, which greatly increases the security risks of intelligence collectors and positions. Mainly because the traditional cable signal transmission is limited by bandwidth, the distance between the information center and the radar should not exceed 300 meters. The use of fiber optic technology can make the information center 10 kilometers away from the radar, which greatly increases the security.
(3) Application on night vision
In order to ensure the military’s need for nighttime operations, the invention of night vision devices played an important role, and the application of fiber optic technology to night vision devices can be used to help rifle aiming, protect eyepieces, observe at night, and so on. At present, night vision devices are constantly being updated and upgraded, and the use of optical fiber components can greatly improve the clarity of images, which is conducive to the development of night detection work.
4. Application in the Air Force
The development of science and technology has led to a rapid increase in the aircraft manufacturing industry and higher requirements for aircraft. Due to the large number of electronic devices in the aircraft control system, a large number of cables are required for connection, and each electronic device needs to be operated very high. The signal transmission rate, the noise generated by it is relatively large. On the one hand, noise interferes with signal transmission. On the other hand, excessive noise will have some impact on electronic equipment, and there are potential safety hazards. The traditional treatment method is to use shielding measures for cables. This invisibly increases the cost and aircraft weight, which has a certain impact on the performance of the aircraft, which is not conducive to the flexibility of air operations.
When dealing with the signals on the aircraft, various problems will be encountered. For this, the large-aperture optical fiber line should be used to connect with the various systems on the aircraft, which can effectively reduce the weight of the line and improve the flexibility of the aircraft. At the same time, it is conducive to maintaining the stability between the equipment on the aircraft and strengthening the connection between the aircraft and the ground command center. On the one hand, the fiber-optic signal emitted by the command center has strong anti-interference ability, and avoids electromagnetic interference, radio frequency interference, etc., which affects the aircraft signals receiving. On the other hand, effectively increase the communication distance between the command center and the front line, avoiding the front line being too long to transmit signals and affecting the war situation.
