An optical fiber which includes a light transmitting center portion, a protecting layer and a stress preventing layer. The protecting layer concentrically surrounds the center portion, and reduces the effect of environmental factors on the center portion. The stress preventing layer concentrically surrounds the center portion and is positioned between the protecting layer and the center portion. The stress preventing layer has a Youngs Modulus substantially lower than the Youngs Modulus of the protecting layer, for preventing stress from being transferred from the protecting layer to the center portion. The optical fiber can be used in a filler optic sensor system.
