A technician performs 10 sets of comparative tests on the compression resistance of the optical cable according to embodiment 1 of the present invention (in which the optical fiber ribbon is used for replacing the optical fiber in the optical communication component 5) and a conventional GYDGTY type optical cable, wherein the thicknesses of the optical cable according to embodiment 1 of the present invention (in which the optical fiber ribbon is used for replacing the optical fiber in the optical communication component 5) and the outer sheath of the GYDGTY type optical cable are the same, and the following test data: the maximum pressure to which no significant additional damping is applied, as required for example in the YD/T901 standard, is given in the following table (unit: N/100 mm):
according to the data comparison, the optical cable with the structure of the invention is used, on the premise that the optical fibers are the same and have no additional attenuation, the pressed position is on the outer sheath corresponding to the first reinforcing member, and the maximum pressure borne by the optical cable is 86.8% higher than that of the common GYDGTY optical cable; the compressed position is on the outer sheath corresponding to the second reinforcer, and the maximum pressure borne by the optical cable is 51.4% higher than that of the ordinary GYDGTY optical cable; the maximum pressure of the optical cable is 16.8% higher than that of the ordinary GYDGTY optical cable when the optical cable is pressed on the outer sheath corresponding to the non-first reinforcing part or the second reinforcing part.
Therefore, the invention has the advantages of simple structure, good tensile property, good compression resistance, good torsion resistance, good heat dissipation performance and the like.
The invention solves the problem of poor compression resistance at the gap between two adjacent supporting frameworks.
The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be construed as limiting the present invention. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
