Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cables, in particular to a hangable multi-core optical cable. Background Art

[0002] The hangable multi-core optical cable is a specially designed fiber optic communication cable. It consists of multiple optical fiber cores encapsulated in a protective layer. The outer layer is usually covered with multiple protective materials such as tensile resistance, moisture resistance, and UV resistance. It has a special outer protective structure and tensile design. It is suitable for scenarios where optical fiber communication transmission needs to be suspended on aerial structures such as building exterior walls, telephone poles, and bridges. This type of optical cable usually adopts a special protective outer casing and reinforced tensile wire to ensure good durability and reliability in various harsh environments. The characteristics of the hangable optical cable include strong weather resistance, high tensile strength, easy installation and maintenance, etc. It is widely used in the construction and expansion of outdoor fiber optic communication networks in cities and rural areas.

[0003] The existing hangable multi-core optical cables are basically fixed on utility poles or the outer walls of buildings by using bolts and fixing clamps, and some length is reserved for the hangable multi-core optical cables to prevent insufficient connection length. Therefore, an optical cable reserve rack is installed on one side of the utility pole or the outer wall of the building for use during maintenance and inspection. However, when the reserved optical cable length is longer, the number of turns of the optical cable is more, and the fixed-length reserve rack clamp is difficult to fix the optical cable with a large number of turns. A customized reserve rack clamp is required to fix the optical cable with a large number of turns. During maintenance, removing the protective leather is time-consuming and may damage the optical cable. Frequent operation also affects the life of the leather. This fixing method reduces the efficiency of maintenance and inspection to a certain extent.

[0004] Therefore, it is necessary to provide a new hangable multi-core optical cable to solve the above technical problems. Utility Model Content
