- a material for the outer cover that is transparent a material whose tensile strength, elongation at break, hardness, etc. are adjusted using any of urethane resin, soft acrylic resin, PVC, polypropylene, low-density polyethylene, and nylon as a base material. By applying, it is possible to ensure the necessary characteristics and sufficient transparency for the cable jacket.
- the cross-sectional shape of the indoor cable is substantially rectangular, and if the width of the long side of the indoor cable is 3.1 mm or less, the size of the indoor cable is not too large and is not noticeable. Moreover, if the width
- FIG. 1 Sectional drawing of the indoor cable 1.
- FIG. 1 is a cross-sectional view of the indoor cable 1.
- the indoor cable 1 includes an optical fiber core wire 3, a tension member 7, an outer jacket 11, and the like.
- the optical fiber core wire 3 and the tension member 7 are integrated by a jacket 11.
- the jacket 11 is made of a transparent material.
- a transparent material constituting the outer cover 11 a material in which tensile strength, elongation at break, hardness and the like are adjusted using any one of urethane resin, soft acrylic resin, PVC, low density polyethylene, and nylon as a base material is applied. be able to.
- the indoor cable 1 has a substantially rectangular cross-sectional shape in the same manner as a commonly used indoor cable.
- the width (B in the figure) of the long side of the indoor cable 1 is 1.7 mm to 3.1 mm. If the width of the indoor cable 1 becomes too large, the indoor cable 1 is easily noticeable. Moreover, when the width
- Notches 9 are formed at positions facing each other on the upper and lower surfaces of the outer cover 11 of the optical fiber core wire 3 (outer peripheral surfaces in a direction perpendicular to the direction in which the tension member 7 is provided).
- the outer cover 11 is broken from the upper and lower notches 9 with a cable dividing tool, a nipper or the like, the inner optical fiber core wire 3 can be separated from the tension member 7 and the outer cover 11 and taken out.
- the optical fiber core wire 3 is made of a glass strand and a resin coating (primary resin layer and secondary resin layer). Conventionally, the optical fiber core wire 3 of the present invention does not have a colored layer formed on the outer periphery of the resin coating layer. That is, the optical fiber core wire 3 is made of a transparent material as a whole.
- optical fiber core 3 for example, a conventional optical fiber core having a diameter of 0.20 mm or 0.25 mm can be applied. Moreover, an overcoat layer can be formed in the outermost layer to make the diameter 0.5 mm or 0.9 mm.
- the overcoat layer is also made of a transparent material.
- thermoplastic resins such as PVC, styrene elastomer, fluorine rubber, silicone rubber, polycarbonate, nylon, urethane, polyester elastomer, and low molecular polyethylene, and ultraviolet curable resins such as urethane acrylate can be applied.
- the optical fiber core 3 may have a diameter of 0.20 mm or 0.25 mm, for example. desirable.

- the matrix resin of the fiber reinforced plastic is desirably an acrylic resin such as PMMA with high transparency, polycarbonate, or polystyrene, instead of an unsaturated polyester having a high diffused light ratio. By doing so, the transparency of the tension member 7 can be increased.
- glass fiber FRP with high transparency can be obtained by using glass fiber with high transparency that has been processed at high temperature to remove impurities.
- all transparent materials constituting the indoor cable 1 have a total light transmittance of 60% or more as defined in JIS K7361-1. This is because when the total light transmittance is less than 60%, the color of the indoor cable 1 becomes strong and stands out. More preferably, the total light transmittance of the indoor cable 1 is 80% or more.
- all the transparent materials constituting the indoor cable 1 have a haze value defined by JIS K7136 of 15% or less.
- the haze value is expressed as diffuse transmittance / total light transmittance ⁇ 100%. This is because when the haze value exceeds 15%, the haze increases and becomes conspicuous.
- a material constituting the tension member 7 and the jacket 11 a material having a refractive index (for example, 1.46 ⁇ 0.2) close to about 1.46 which is the refractive index of the optical fiber core 3 is selected. Is desirable.
- the adhesive applied to the outer periphery of the tension member 7 has a thin film thickness
- a conventional adhesive can be used as it is.
- the optical fiber core wire 3, the tension member 7, and the outer sheath 11 that constitute the indoor cable 1 are all made transparent, so that they are not conspicuous during indoor wiring. You can get an indoor cable. That is, even if an optical fiber core wire, a cable, and the like are individually wired, the present invention combines all of these so that the indoor aesthetics are not impaired. By making the structure transparent, it is possible to obtain a new effect that it is inconspicuous during indoor wiring. (I changed it according to the situation at the time of use)
- ⁇ Multi-type indoor cables were prototyped, wired to the corners of the indoor walls and floors, and visually evaluated for their conspicuousness. The conspicuousness was judged from a place about 1 m away from the laid indoor cable. Table 1 shows the indoor cable size and evaluation results.
- the short diameter of the cable is dimension A in FIG. 1, and the long diameter of the cable is dimension B in FIG.
- Samples 1 to 5 were all optical fiber cores (0.25 mm diameter) without a colored layer, and 0.45 mm diameter glass fiber FRP was used as the tension member.
- the distance between the notch tip and the fiber was 0.3 mm.
- As the outer jacket a highly transparent soft acrylic resin was used.
- the indoor cable was visually observed by the above-described method. A case where it was inconspicuous was marked with ⁇ .
- the drop cable may be configured by integrating the indoor cable 1 of the present invention and the support wire with another outer cover.
- the other jacket does not need to be transparent, and conventional resins can be used in consideration of weather resistance and the like.
