Patent ID: 7822307

Claim:
An optical fiber ribbon for wiring of equipment, the optical fiber ribbon being formed in a ribbon-like shape such that a plurality of coated optical fibers are arranged in parallel and coated as a whole with a collective coating made of ultraviolet curable resin, wherein each coated optical fiber has an inner fiber coating layer and an outer fiber coating layer, each made of ultraviolet curable resin, the Young's modulus of the inner fiber coating layer being in the range of 600 MPa to 1000 MPa, the Young's modulus of the outer fiber coating layer being in the range of 10 MPa to 300 MPa; and wherein the outer fiber coating layer is a material made by mixing 100 weight parts of base resin, 1-30 weight parts of silicone-based additive, and 0.5 to 40 weight parts of long chain fatty acid ester compound.
