Four major reasons for the failure of communication fiber optic cable lines

As we all know, an integrated wiring project is a complex undertaking, and it's impossible to guarantee zero failures throughout the entire construction process. However, it's definitely possible to minimize the occurrence of errors and issues. Today, we're going to discuss four common reasons that lead to failures in communication fiber optic cable lines.

First: The Impact of Lightning

Fiber optic cables are typically armored with metal components, which act as conductors. If a power line experiences a short circuit or if lightning strikes the metallic parts of the cable, it can generate a powerful current that damages the cable and its associated equipment. In extreme cases, this can even result in injuries or fatalities.

Second: Poor Insulation of the Optical Cable Line

If the insulation of a communication fiber optic cable is inadequate, the cable's structural integrity can be severely compromised over time. This often happens due to stress corrosion or static fatigue when moisture enters the joint box or the cable sheath. In the worst scenarios, the cable may break entirely, leading to service interruptions.

Third: Damage from External Forces

Many fiber optic cable lines are installed in open fields, where they are exposed to various external threats. Although they are usually buried deep underground, it's still difficult to completely protect them from damage caused by construction activities, vehicle traffic, or natural elements like tree roots and soil movement.

Fourth: Faults at the Line Joints

The most common point of failure in fiber optic networks is at the line joints. This is because the fiber at the joint is not fully protected, or the protection has been weakened during installation. As a result, the joint box becomes the primary defense against environmental and mechanical stresses. Unfortunately, this increases the likelihood of failure, especially if the joint is not properly sealed or maintained.

Aluminium Awning Windows

Aluminum alloy sunshade window is a product that combines sunshade function with windows, with the following characteristics:
1. Structural design
Frame
Made of aluminum alloy profiles, aluminum alloy has high strength, light weight, corrosion resistance, and can ensure the stability of the window structure. Its profiles can be made into different shapes and sizes according to design requirements to meet the requirements of various building openings.
Sunshade part
Common sunshade methods include built-in sunshade blinds and external sunshades.
Built-in sunshade blinds are blinds installed between two layers of glass, and the amount of sunlight entering is controlled by adjusting the angle of the blinds. This method can effectively protect the blinds from the influence of the external environment, reduce the damage to the blinds by dust, rain, etc., and also enhance the overall aesthetics of the window.
External sunshades are sunshades installed on the outside of the window, and the position of the sunshade can be adjusted according to the angle of the sun. The sunshade effect of the external sunshade is more direct, and it can block more sunlight heat from entering the room, but it is necessary to consider its impact on the appearance of the building and its wind and rain protection performance.
2. Functional characteristics
Shading and heat insulation
Effectively block solar radiation heat from entering the room and reduce the energy consumption of indoor air conditioning. According to different shading forms and shading coefficients, it can block 50% - 80% or even more solar heat, which can significantly improve the thermal comfort of the room in summer.
Lighting adjustment
Built-in sunshade blinds or adjustable external sunshades can adjust the incident angle of sunlight and the amount of light entering the room as needed. For example, soft light can be allowed to enter the room in the morning or evening, while the sunlight is completely blocked when the sun is strong at noon, realizing flexible lighting control.
Privacy protection
When the built-in sunshade blinds are adjusted to the appropriate angle, the privacy of the room can be protected without affecting the lighting, which is especially practical for some low-rise buildings or rooms close to the street.
3. Applicable scenarios
Residential
Suitable for installation in bedrooms, living rooms and other rooms, which can not only meet the lighting and ventilation needs, but also effectively control sunlight and heat, and improve the comfort of living.
Commercial buildings
In offices, shopping malls and other places, aluminum alloy sunshade windows help reduce air conditioning energy consumption, and can flexibly adjust the lighting and shading effects according to different usage needs.
