Uniform bending losses of single-mode fibers are experimentally studied. The effects of a dip in the refractive index at the center of the core, bending radius and fiber parameters on the bending losses were investigated. An experimental equation for the bending loss of a single-mode fiber with a small dip have been obtained as an exponential function of the bending redius and the fiber parameters. It essentially agrees with the theoretical equation.
