In the defense sector, infrastructure is subject to extremely high demands, particularly when it comes to the cabling of communication and data systems. Standard fiber optic cables, which are widely used in civilian applications, prove inadequate in this environment. Robustness and resistance to extreme conditions are critical factors, making conventional solutions fall short of the required standards. In such challenging scenarios, the metallic fiber optic cable BRUmil from Solifos is employed, specifically developed for military and highly sensitive applications.
Why Standard Fiber Optic Cables Fail
Conventional fiber optic cables are made with plastic coatings and designed for everyday use in relatively stable and safe environments. They lack sufficient resistance to mechanical stress, such as impacts, crushing, or damage caused by rodents—a frequently underestimated issue in outdoor applications. Particularly in military operations, where cables are often laid and used under extreme conditions—such as rugged terrain, humid environments, or intense mechanical stress—standard fiber optic cables can quickly become damaged, leading to critical failures.
The Advantage of Metallic Fiber Optic Cables Like BRUmil
The BRUmil fiber optic cable from Solifos sets a new standard in this regard. Its special construction makes it ideal for the defense sector and other high-risk environments. The key feature of this robust solution lies in its additional metallic protective layer. The optical fibers are shielded by a stainless steel tube and stainless steel wire armoring, which makes the cable resistant to strong mechanical stress, crushing, and even sharp objects.
Additionally, this type of cabling provides effective protection against rodent bites—a problem that can lead to unexpected failures in many military and industrial environments. This combination of mechanical stability and protection against biological threats makes the BRUmil cable the top choice for durable and secure cabling solutions in the defense sector.
Advantages in the Civilian Sector?
The benefits of metallic fiber optic cables like BRUmil are also recognized in civilian high-security sectors. This technology is not only employed in defense but also in prestigious projects. A recent example is the new Federal Chancellery, where BRUmil cables are installed to meet the highest standards of security and reliability. Similar cable systems are also used in numerous other security-critical facilities.
Conclusion
In security-relevant areas like defense, the use of standard fiber optic cables is a risky and often inadequate solution. The BRUmil from Solifos offers a significantly more robust alternative thanks to its stainless steel protective layer, making it resistant to mechanical stress and rodent damage. Investing in such specialized fiber optic cables is not only sensible but often essential to ensure the long-term and reliable protection of critical infrastructures and communication systems.
