Description

Technical Field

[0001] This utility model relates to the field of composite optical cable technology, specifically a self-supporting composite optical cable. Background Technology

[0002] Optical-optical composite cable refers to a transmission line suitable for broadband access network systems. It is a new type of access method that integrates optical fiber and copper power transmission wire. It can solve the problems of broadband access, equipment power supply and signal transmission. Self-supporting composite optical cable refers to an optical cable that has the mechanical strength to withstand its own weight and external load.

[0003] The patent CN216161488U discloses a self-supporting optical-electric composite cable. This patent discloses a technical solution to improve service life and solves the problem that the existing self-supporting optical-electric composite cables have a relatively simple structure. Most of them have a single sheath with an additional layer of steel or aluminum tape armor, which is only suitable for good laying environments and not suitable for harsh and complex environments, such as remote mountainous areas, tunnels, old urban areas, etc. In these environments, there may be problems such as water accumulation, landslides, and rampant rodent infestations. The optical-electric composite cable cannot fully meet the requirements of the above-mentioned complex environments.

[0004] When in use, the device provides a certain degree of rodent protection to the optical cable through the action of the steel pipe. The steel tape wrapping armor layer has better mechanical properties. However, when using composite optical cables, it is not convenient to adjust the installation position, which reduces the stability of the connection between the reinforcing member and the sheath. Therefore, a self-supporting composite optical cable is proposed to solve the above problems. Utility Model Content
