FIG. 1 is a cross-sectional view showing an embodiment of the branched optical fiber undercarpet cable of the present invention;
FIG. 2 is a cross-sectional view showing another embodiment of the present invention, FIG. 3 is a cross-sectional view showing a conventional optical fiber undercarpet cable, and FIG. 4 is a branched optical fiber undercarpet cable of the present invention. Regarding cables, we investigated the increase in optical fiber transmission loss due to lateral pressure load due to bending, when the hardness of the optical fiber-filled pipe and the reinforcing wire-filled pipe were made the same, and when the optical fiber-filled pipe was made softer. FIG. 5 is a graph showing the increase in optical fiber transmission loss when the two types of cables are laid in a crossed manner and lateral pressure is applied from above. 1...
