Cable lines and optical fibers play a key role in the transmission of electrical and optical signals in various fields, such as telecommunications, energy and computer networks. However, due to its strategic importance and exposure to various external factors, it is necessary to properly protect these lines against damage, which can lead to failure, delivery breaks or signal loss. In this article, we will present key aspects of cable and optical fiber protection and methods that are worth using to reduce the risk of failure.

What should you protect cable lines and optical fibers from?

When laying cable lines or blowing fibers, the most important is protection against excessive friction, which can lead to damage. Therefore, preparations such as cable slip or fiber fluid are used. Thanks to them, friction is reduced to a minimum. However, damage is also possible during operation, which is why you also need to take care of good technical condition of cable lines and optical fibers.

1. Protection against mechanical damage

One of the main threats to cable lines and optical fibers are mechanical damage caused by e.g. excavations, construction works, etc. To prevent such damage, it is necessary to properly mark and protect cable routes as well as regular inspections to detect any threats. In addition, the use of appropriate cable shields, such as protective pipes or channels, significantly increases the durability and resistance to damage.

2. Protection against weather conditions

Atmospheric factors such as rain, wind, frost or UV radiation can cause degradation of cable lines and optical fibers. The impact of these factors can lead to the erosion of insulation materials, corrosion of metal elements or degradation of optical fiber optic fibers. That is why it is important to use appropriate materials and constructions resistant to atmospheric factors as well as regular inspections and maintenance that will allow you to detect and repair possible damage.

3. Protection against the effects of chemicals

Some environments, e.g. associated with the chemical industry or transformer stations, can be exposed to chemicals that negatively affect cable lines and fiber. Contact with inappropriate chemicals can lead to corrosion, degradation of insulation materials or loss of conductivity. In such cases, it is necessary to use special protective and insulation materials that are resistant to chemicals.

4. Protection against external threats

In some areas, there are additional threats, such as earthquakes, fires and acts of vandalism, which can damage cable lines and optical fibers. To minimize the risk of such damage, it is necessary to properly secure and mark cable routes, use durable construction materials and monitor areas exposed to this type of threat.

What negatively affects optical fibers?

One of the extremely harmful factors is water, because at low temperatures it can lead to the formation of gaps, cable burst and damage to the glass core. Water molecules can connect to mockered molecules and core, which is why silicon hydroxides are formed. As a result of these processes, the properties of the fiber are significantly deteriorated, and even the so -called Glass cancer, i.e. irreversible changes in the glass structure, deteriorating its mechanical and optical properties. To prevent such problems, polymer coatings and gel buffers are used.

The temperature, both low and high, can also have harmful effects. The fibers shorten or extend, which is why mechanical core stresses appear, leading to its damage or even interruptions.

Another problem is the so -called Mechanical stress. It causes it to change temperature and humidity and vibrations. The risk of such damage reduces the use of high density polyethylene - HDPE.

How to protect cable lines?

Numerous tools are available, which minimally reduces the risk of cable damage at the stage of their incurrence and laying. Among other things, battery scissors or a cable skis are used. However, it is also important to secure cables during operation. One of the key aspects is the marking of the cable line. Underground elements such as warning tapes, electromagnetic markers and protective plates are used here.

Protection of cable lines and optical fibers is extremely important to ensure reliability and transmission safety. Therefore, regular inspections, appropriate protective and insulation materials and proper marking are necessary.
