Description

Technical Field

[0001] The utility model relates to the technical field of communication optical cables, and more particularly to a communication optical cable protection structure. Background Art

[0002] As society becomes increasingly modernized, information transmission efficiency is increasing. With the gradual development of power communication networks, the use of optical cables is becoming more and more popular. Optical cables are a combination of multiple optical fibers twisted together and are currently the most promising transmission media. However, existing optical cables only rely on the outer skin for protection and are easily damaged in harsh operating environments. Therefore, additional protective structures are needed.

[0003] Common protective structures are mostly simple shells that cover the optical cable to ensure that the optical cable is protected from erosion by the external environment and gnawing by animals such as rats. However, the ordinary shell structure is thin and has low mechanical strength. Although it can resist external contact, it is easily damaged and broken when encountering strong external impact. When the impact is concentrated in a certain place, it is more susceptible to damage and affects the internal optical cable. Moreover, when laying the optical cable, it is sometimes necessary to bend the optical cable to lay it at a certain angle. When the optical cable is bent, the surface of the optical cable is easily affected by stress, which The inner side of the bend is squeezed and the outer side is stretched. Generally, there is no restrictive structure inside the protective shell, and the optical cable will be randomly piled up inside the protective shell. At this time, if the bending degree of the optical cable is large, the bending part is prone to damage. In addition, when the optical cable is actually laid, because the distance of the optical cable is long, the protective shell will also be divided into multiple parts, and will be combined as the optical cable is laid. However, the common protective shell structure is simple, and the combination of the shells only relies on tight fit. Gaps will inevitably be left between the shells, resulting in incomplete protective structure and incomplete protection of the internal optical cable. Utility Model Content
