[0002] Optical cables are the infrastructure of optical communication networks, and their application scenarios are relatively diverse. They need to be laid not only in urban areas and their peripheries but also in wild areas such as mountainous woodlands. To ensure the normal and stable operation of the optical communication network, the optical cables laid in the wild area need to have a certain anti-bird-pecking function, especially the overhead optical cables need to have better anti-bird-pecking performance. Due to factors such as ecological protection and implementation costs, the optical cable line should not adopt the scheme of poisoning or killing birds, and it is necessary to improve the strength and expulsion effect from aspects such as the structural design and material selection of the optical cable itself.
[0003] The existing anti-bird-pecking solutions for optical cables mainly include adding an armor layer, hanging colored flags, painting warning colors on the sheath, and selecting excellent new optical cable materials. Among them, the method of adding a metal or non-metal armor layer is the most commonly used means. To improve the anti-bird-pecking performance, it is necessary to continuously increase the thickness of the armor layer and the outer sheath of the optical cable, which will result in a larger outer diameter, heavier weight, higher production cost of the optical cable, and higher laying difficulty and cost of the optical cable, especially difficult for overhead laying.
[0004] In summary, there is a need in the art to improve the existing anti-bird-pecking optical cables, and reduce the outer diameter and weight of the optical cable on the premise of ensuring the anti-bird-pecking effect and transmission performance, so as to reduce the laying difficulty, production cost and laying cost.
