2016-10-21

Under the conditions of information warfare, the military communication system is the nerve center for command control and intelligence transmission. As a transmission medium, special optical fiber cables play a vital role in ensuring communication stability and improving communication speed. In view of the special needs of future battlefields, it is of great strategic significance to study the innovative application of special optical fiber cables.

 

Technical characteristics of special optical fiber cables

 

Special optical fiber cables need to adapt to the complex environment of future battlefields and have characteristics such as resistance to electromagnetic interference, resistance to high and low temperatures, and resistance to corrosion. Its unique design supports high-speed data transmission and offers significant advantages in confidentiality, invulnerability and reliability. The military-grade technical characteristics of special optical fiber cables will be introduced in detail below:

 

1. High transmission rate: Military field optical cables are composed of multiple optical fibers in parallel. There are two types of optical fibers currently used. One is short-distance OM3 and OM4 multimode optical fibers, which are mainly used for short-distance ultra-high-speed transmission; the other is long-distance G652D, G654E, G657A2 and other single-mode optical fibers for ultra-long-distance transmission. The general transmission distance is at the kilometer level, and the longest ultra-long-distance transmission is tens to hundreds of kilometers. In addition, the signal loss is small during the ultra-long-distance transmission process, which can ensure ultra-long-distance stable transmission, and the transmission loss value of G654E optical fiber can be as low as 0.165-0.175dB/KM.

When the enemy implements electromagnetic interference, the communication optical cable can ensure the stability of communication quality. This feature is very important in wartime military communications and can effectively avoid electromagnetic signal interference.

 

4. Resistance to harsh environments: In terms of special optical fibers, the latest developed new optical fibers have added high-temperature resistant molecular materials to the optical fiber coating, and the external structure also uses silicone or fluorine-containing materials. Fluorine-containing materials have high strength and environmental resistance, and also have obvious advantages in flame retardancy and bending resistance. They can fully meet the use in complex environments and can maintain performance in extreme environments. They also have excellent corrosion resistance and are suitable for various battlefield conditions.

 

5. Lightweight design: Compared with traditional copper cables, optical fiber cables are lighter. At the same time, we also fully consider the miniaturization design when designing, making the product size as small as possible, so as to facilitate rapid deployment and mobile operations.

 

6. Various sensing applications: Special optical fibers are also widely used in the field of sensing, such as the cutting-edge Panda-type polarization-maintaining optical fiber, rotating optical fiber, fiber Bragg grating, etc., which are used for high-precision sensing measurements.

 

7. Confidentiality and security: Fiber-optic communication has natural confidentiality and is difficult to be intercepted or strongly electromagnetically interfered with, which is crucial to the security of military communications.

(2) Software Defined Networking (SDN) and Network Function Virtualization (NFV):

 

These technologies make network architecture more flexible and programmable, enabling it to quickly adapt to changes in the battlefield environment and achieve optimal resource allocation.

 

(3) 5G/6G communication technology:

 

The new generation of mobile communication standards will provide higher data rates, lower latency and greater connection density, which is essential for real-time command and control, drone swarm control and the integration of IoT devices.

 

(4) Edge computing:

 

Deploying computing power to the edge of the network reduces reliance on central servers, reduces latency, and increases data processing speed, which is particularly important in remote battlefield environments.

 

(5) Cognitive radio:


Cognitive radio can sense and adapt to the spectrum environment around it, automatically select the best frequency band for communication, and effectively avoid interference and spectrum conflicts.

 

(6) High-throughput satellite communications:


Using more advanced satellite technologies, such as Ka/Ku band and laser communications, it provides high-bandwidth and global coverage communications capabilities, which are particularly suitable for ocean and air operations.

 

(7) Miniaturization and wearable technology:


Develop communication equipment with smaller size, lighter weight and lower power consumption, which is easier for individual soldiers to carry and use, and improves battlefield survivability.

 

(8) Artificial intelligence and machine learning:


AI is used for network management, threat detection, signal processing, and adaptive routing to improve the intelligence level and autonomous operation capabilities of the network.

 

(9) Blockchain technology:


Provides a decentralized authentication and data transmission mechanism to enhance the transparency, security and tamper-proof capabilities of communication networks.

 

(10) Autonomous network repair and self-organizing networks (SON):


Self-organizing networks can automatically detect faults and reconfigure the network, reducing dependence on manual maintenance and improving network robustness.

 

(11) Multi-domain joint communications:


Integrate satellite, air, ground, and underwater communication systems to form a comprehensive communications network to ensure seamless communications in all combat domains.

 

(12) Metamaterials and Nanotechnology:


Develop new materials and structures for antennas, RF components and sensors to improve the performance and stealth of communication equipment.

 

The comprehensive application of these innovative technologies will significantly improve the communication efficiency of future battlefields and provide strong information support for military operations.

 

Conclusions

 

The innovative application of special optical fiber cables in future battlefields will greatly improve the performance of military communications and ensure the stability and security of communications in complex battlefield environments. The research and development and application of related technologies will provide strong support for command, control and intelligence transmission under information warfare conditions.
