Self-supporting access network butterfly-shaped indoor optical cable: How to ensure long-term stable operation and reduce failures?

One of the core advantages of the butterfly-shaped indoor optical cable for self-supporting access network is its unique self-supporting design. During the installation and use of traditional optical cables, additional support structures are often required to withstand the weight of the optical cable itself and the physical stress caused by the external environment, such as stretching and bending. This not only increases the installation cost, but may also cause the performance of the optical cable to deteriorate or even fail due to the instability or failure of the supporting structure. Self-supporting optical cables, on the other hand, have built-in strengthening elements (such as aramid yarn or steel wire) to make the optical cable itself have sufficient tensile and bending resistance.
Tensile resistance:
The strengthening elements inside the self-supporting optical cable can withstand the gravity stretching generated by the optical cable when it is installed vertically or obliquely, effectively preventing the optical cable from deforming or breaking due to excessive stretching. This design is particularly suitable for vertical wiring scenarios inside high-rise buildings or data centers, reducing the sagging and stretching problems caused by the excessive length of the optical cable.
Bending resistance:
The optical cable will inevitably encounter bending during the wiring process, and a small bending radius will cause the optical signal inside the optical fiber to attenuate, affecting the transmission performance. Self-supporting optical cables improve the bending resistance of optical cables by optimizing the structure of optical fiber and sheath materials, so that optical cables can still maintain stable transmission performance at a smaller bending radius.
Simplified installation and maintenance:
The self-supporting design also simplifies the installation and maintenance process of optical cables. Since the optical cable itself has the support capacity, no additional support structure is required, which reduces the installation time and cost. At the same time, the self-supporting optical cable has clear identification, easy to identify and manage, and improves maintenance efficiency.

In addition to the self-supporting design, the butterfly-shaped indoor optical cable for self-supporting access network is also made of high-quality materials, which further improves the weather resistance and anti-aging performance of the optical cable and ensures long-term stable operation.
Fiber material:
The core of the optical cable is the optical fiber, and its performance directly affects the transmission quality of the optical signal. Self-supporting optical cables use high-performance optical fibers with low attenuation and high bandwidth, which can support high-speed and large-capacity data transmission. At the same time, the surface of the optical fiber is specially treated to improve the scratch resistance and corrosion resistance and extend the service life.
Sheath material:
The sheath is the protective layer of the optical cable, and its main function is to prevent the optical fiber from being damaged by the external environment. Self-supporting optical cables use low-smoke zero-halogen (LSZH) materials as sheaths, which not only meet environmental protection requirements, but also have good flame retardant properties and weather resistance. This material can maintain stable performance in harsh environments such as high temperature, humidity, and corrosion, and effectively prevent the optical cable from aging or damage due to external environmental factors.
Reinforcement element materials:
The reinforcement elements inside the self-supporting optical cable usually use high-strength materials such as aramid yarn or steel wire. These materials have excellent tensile and bending resistance, and can maintain the stability of the optical cable under extreme conditions. At the same time, these materials also have good corrosion resistance, can resist the erosion of chemicals such as acids and alkalis, and extend the service life of the optical cable.

self-supporting bow-type drop cables have been widely used in data centers, high-rise buildings, smart homes, communication base stations and other fields. Its unique self-supporting design and high-quality material manufacturing make the optical cable perform well during installation and use, and has the following significant advantages:
Improve network stability:
Self-supporting optical cables effectively reduce the performance degradation or failure of optical cables caused by physical stress such as stretching and bending by enhancing the ability to withstand physical stress, and improve the stability and reliability of the network.
Reduce installation costs:
The self-supporting design simplifies the installation process of the optical cable, reduces the need for additional supporting structures, and reduces installation costs and time. At the same time, the optical cable is clearly marked, easy to identify and manage, and improves installation efficiency.
Extend service life:
The application of high-quality materials makes the optical cable have good weather resistance and anti-aging properties, and can maintain stable performance in harsh environments, extending the service life of the optical cable.
Support high-speed data transmission:
The high-performance optical fiber and low attenuation characteristics enable self-supporting optical cables to support high-speed, large-capacity data transmission, meeting the high bandwidth and speed requirements of modern communication networks.
Environmental protection and safety:
The use of low-smoke halogen-free material as the sheath not only meets environmental protection requirements, but also improves the flame retardant properties of the optical cable and reduces the risk of fire.
