However, after the multiple loose tubes are stranded around the cushion layer, in order to keep the loose tubes stable in structure, the loose tubes are often damaged and broken by wrapping the yarn materials, and the yarn materials are often broken by the loose tubes during temperature change due to different expansion and shrinkage rates of the yarn materials and the loose tube materials, even internal optical fibers or optical fibers, so that optical communication is affected, and transmission of optical fiber signals such as televisions, audios, telephones, data and control is affected. On the other hand, yarn bundling is usually only performed in a spiral manner, and the yarn bundling is required to be unreeled or cut off during inspection or construction, so that quick resetting is difficult; similarly, there are corresponding drawbacks to the lay loose tube construction.
