In the diverse fields of optical cable design, the figure-of-eight structure occupies an important position in water-blocking armored optical cable with its unique design and significant advantages. This design not only optimizes the structure of the optical cable, but also significantly improves its performance and stability in practical applications.The optical cable structure with the figure-of-eight design mainly consists of two parts: the upper part includes strain bearing parts, which are made of high-strength materials such as aramid yarn, and are used to withstand various stresses that the optical cable may encounter during laying and use; the lower part includes the cable core, which is composed of one or more stranded buffer tubes, which are filled with special grease to provide critical protection for the optical fiber. Both the upper and lower parts are covered with a polyethylene sheath to form a double sheath structure, which further enhances the water-blocking performance of the optical cable.In terms of water blocking, the optical cable with the figure-of-eight design adopts a full-section water-blocking structure to ensure that the interior of the optical cable is not intruded by water, thereby ensuring the stability and reliability of optical fiber transmission. This design is particularly suitable for wet environments, such as the seabed, near rivers or lakes, and environments that require direct burial.In addition, the 8-shaped structure also gives the optical cable self-supporting aerial performance. Its compact structure makes the optical cable soft and easy to construct, without the need to set up suspension wires and hooks, which greatly improves construction efficiency and reduces installation costs. This design is particularly suitable for mountain communication construction or urban short-pole-distance optical cable aerial introduction.In terms of mechanical properties, the 8-shaped water-blocking armored optical cable also performs well. The phosphating steel wire central reinforcement member and steel wire strands are used inside, giving the optical cable extremely high tensile strength and resistance to lateral pressure. This design not only enhances the durability of the optical cable, but also enables it to withstand mechanical stress in harsh environments, such as the laying and salvaging tension that submarine optical cables need to withstand.In general, the 8-shaped design plays a unique role in the water-blocking armored optical cable structure in many aspects. It optimizes the structure of the optical cable, enhances the water-blocking performance, improves construction efficiency, reduces installation costs, and significantly improves the mechanical properties and stability of the optical cable. These advantages make the figure-8 water-blocking armored optical cable widely used in long-distance communication, local communication, and communication scenarios that require high reliability and stability. In the future, with the continuous advancement and innovation of technology, the figure-8 optical cable is expected to play its unique advantages in more fields and make greater contributions to the development of the communications industry.
