[0034] figure 1 It is a schematic diagram for explaining the optical fiber cable of 1st Embodiment of this invention.
[0035] The optical fiber cable 100 is composed of an optical fiber core 140 and a jacket 160 covering the optical fiber core 140 . The jacket 160 plays a role of protecting the optical fiber core wire 140 . figure 1 In the figure, in order to facilitate the observation of the optical fiber core 140, a part of the jacket 160 is omitted from illustration.
[0036] The optical fiber core 140 is composed of a plurality of single-core optical fibers or at least one multi-core optical fiber. The single-core optical fiber may be, for example, one coated optical fiber in which the outer periphery of the optical fiber is coated. In addition, the multi-core optical fiber may be, for example, an optical fiber ribbon in which a plurality of coated optical fibers are integrated, or an intermittent bonding type optical fiber ribbon in which a plurality of coated optical...

[0057] Figure 4A and Figure 4B It is a schematic diagram for explaining the third embodiment of the present invention. This embodiment relates to the structure of the optical fiber cable 100 . Figure 4A It is a schematic diagram of the cross section of the optical fiber cable 100A of this embodiment. Figure 4B It is a schematic cross-sectional view of another optical fiber cable 100B of this embodiment. Figure 4A and Figure 4B , marked with figure 1 and figure 2 The components shown with the same reference numerals are the same components, and detailed description thereof will be omitted.
[0058] like Figure 4A As shown, the optical fiber cable 100A of the present embodiment is composed of one core unit 150 and a jacket 160 for accommodating the core unit 150 . That is, the optical fiber cable 100A has one optical fiber core wire 140 .
[0059] Additionally, if Figure 4B As shown, the optical fiber cable 100B of the present embodiment is composed of a plura...
