[0022] As one of the embodiments in the embodiment, as Figure 4As shown, multiple optical fiber assemblies 1 each include a winding tube 101, which is wound around the outside of the supporting steel strand 6. A positioning tube 102 is fixedly fitted inside each winding tube 101. Multiple fiber-passing holes 103 are arranged in a ring inside each positioning tube 102, and an optical fiber body 104 is fitted inside each fiber-passing hole 103. Each optical fiber assembly 1 includes one winding tube 101. These winding tubes 101 are tightly wound in a spiral shape around the outside of the supporting steel strand 6, forming a stable and orderly optical fiber support structure. The positioning tube 102 is fixedly fitted inside the winding tube 101, serving as a reference for optical fiber arrangement. Multiple fiber-passing holes 103 are arranged in a ring inside the positioning tube 102, precisely designed to accommodate the optical fiber body 104, ensuring that the optical fiber body 104 can be fixed and protected in an optimal layout. Through this structure, the optical fiber body 104 not only receives effective physical support but also avoids cross-interference, thereby ensuring the transmission quality of the optical signal and the overall performance of the optical cable.

[0023] As one implementation method in this embodiment, such as Figure 2 and Figure 3 As shown, the first protective mechanism 2 includes a foam filling core 201, which wraps around the outside of multiple spiral tubes 101. A shielding tube 202 is fitted over the foam filling core 201, and a plastic protective tube 203 is fixedly fitted over the shielding tube 202. The foam filling core 201, as the first protective layer, tightly wraps around the outside of the multiple spiral tubes 101, effectively absorbing external impacts by utilizing the buffering and shock-absorbing properties of the foam material. The foam material also has good heat insulation properties, protecting the internal optical fiber assembly 1 from physical and high-temperature damage. Next, the shielding tube 202 is fitted over... Outside the foam filling core 201, the shielding tube 202 is made of conductive or magnetic material, which can shield electromagnetic interference and ensure that the optical signal is not affected by the external electromagnetic field during transmission, maintaining the clarity and stability of the signal. The outermost plastic protective tube 203 is fixedly sleeved on the shielding tube 202, which not only provides additional mechanical strength, but also has excellent corrosion resistance and waterproof performance, further enhancing the optical cable's ability to resist harsh external environments. These three layers work together to form the first protection mechanism 2 of the optical cable, ensuring the long-term stable operation of the optical cable in complex environments.

The second protection mechanism 3 provides an additional protective layer in the corrosion-resistant communication optical cable, further enhancing the durability and resistance to external corrosion of the optical cable. The inner protective sleeve 301 serves as the first layer of the second protection mechanism 3, directly wrapped outside the plastic protective tube 203 of the first protection mechanism 2, providing preliminary mechanical protection and isolation. On the outside, the outer protective sleeve 302 further reinforces the inner protective sleeve 301, and the two together form a solid protective layer, effectively resisting physical damage. More importantly, the Kevlar woven mesh 4 is wound between the inner protective sleeve 301 and the outer protective sleeve 302. This high-strength, high-modulus synthetic fiber mesh can significantly improve the optical cable's tear resistance and wear resistance, and even in extreme environments, the structure can maintain its integrity. Finally, the heat-shrinkable film 5 is tightly sleeved outside the outer protective sleeve 302, forming a waterproof, moisture-proof, and tightly sealed layer through the heat-shrinkage process, effectively isolating external moisture, humidity, and corrosive substances, further extending the service life of the optical cable. These four layers of structure depend on each other and together build an efficient and reliable second protection mechanism 3, ensuring stable transmission and long-term reliability of the optical cable in various complex environments.
