A roller bearing includes an outer ring, an inner ring, at least one row of rollers arranged between the outer ring and the inner ring, and at least one optical fiber cable mounted to the outer ring or the inner ring, the optical fiber cable including at least one Bragg grating. The optical fiber cable is configured such that a signal in the optical fiber cable is usable to determine a preload or load on the roller bearing.
