Assuming the refractive index distribution in the radial direction is n(r), the refractive index in the center of the core is n1, the relative index difference is ?1, the core diameter is a, the refractive index distribution parameter is a, and " " is a symbol indicative of power in an optical fiber comprising a core and a clad formed on the outer circumference thereof, n(r) is approximated by n(r)=n1[1-2(?1/100)(r/a) a]1/2 for 01/2 for a<r, where a is 1.95-2.15, the relative index difference is 1.5% or above, the diameter of the core is 20-45 µm, the diameter of the clad is 70-90 µm, bending loss at the wavelength of 850 nm is 0.1 dB/turn or less when it is bent with a radius of curvature of 5 mm. An optical fiber and an optical fiber tape which can be produced easily at low cost with low bending loss and capable of high speed optical transmission, and a space saving optical interconnection system which can be produced at low cost are thereby provided. |
