Description

Layer-stranded Optical Cable Field of the Invention The present application relates to the technical field of optical fiber communication, and in particular to a layer-stranded optical cable with different yarn binding pitches. Background of the Invention As shown in Fig. 1, in the related technology, the cable core of the layer-stranded optical cable is stranded into a circle by a plurality of optical fiber loose tubes 2 around the central reinforcing member 1, wherein the optical fiber loose tube 2 refers to the loose tube that accommodates several optical fibers, the metal or non-metal central reinforcing member 1 is located in the center of the optical cable, and the optical fiber loose tubes 2 are arranged around the central reinforcing member 1 with a certain stranding pitch, wherein the stranding pitch is defined as the forward distance of the stranding unit rotating one cycle along the axis of the stranded wire.
In order to prevent the back-twisting of the reversing point, as shown in Fig. 1, the cable core of the layer-stranded optical cable adopts a bidirectional same-point yarn binding method, that is, at least two binding yarns 4 with the same stranding pitch are fixed outside the cable core, and the two binding yarns 4 have different spiral stranding directions. The stranding pitch of the binding yarn 4 is usually between 20mm and 20mm. The stranding pitch of the optical fiber loose tube 2 varies according to the design requirements of the mechanical properties of the optical cable, and the stranding pitch of the optical fiber loose tube 2 can be between 55mm and 500mm.
However, the stranding pitch of the binding yarn 4 should not be greater than that of the optical fiber loose tube 2, so as to ensure that there is enough binding force to fix the optical fiber loose tube 2 into shape without loosening, and at the same time, will not cause the deformation of the optical fiber loose tube 2, so as to avoid the deterioration of the performance of the optical fiber.
When the stranding pitch of the binding yarn and the stranding pitch of the optical fiber loose tube are fixed by technology, in order to improve the production efficiency and increase the unit output, the stranding speed of the cable core can be increased. However, when the stranding speed of the cable core is increased: If the stranding pitches of the two binding yarns remain unchanged, the binding speeds of the two yarn binding machines must be improved. Under the condition of remaining the binding requirements unchanged, it is necessary to improve the control accuracy of the two yarn binding machines so as to improve the binding speeds of the yarn binding machines, resulting in an increase in the production cost of the yarn binding machines.
40 If the stranding pitches of the two binding yarns are increased at the same time to match the increase of the stranding speed of the cable core, the bundling of the cable core will be unstable, resulting in loosening of the loose tube and back-twisting of the reversing point, and possibly unqualified final mechanical properties of the optical cable.

In some embodiments, neither the second stranding pitch nor the third stranding pitch is greater than half of the first stranding pitch. In some embodiments, a plane parallel to the central reinforcing member is taken 40 as a reference plane, and within the range of the first stranding pitch, a projection connecting line of an intersection point of the two binding yarns on the reference plane is a broken line.
