ResumoIn several experiments different glass fibres were periodically distorted by mechanical means. The shape of the distorted fibre was nearly sinusoidal with an amplitude x and a periodic A. These periodic bends induced in all fibres an additional loss αB. For multimode fibres, αB was constant for the measured optical wavelengths from 500 to 1100 nm. When the amplitude x of the distortion is increased, αB increases according to the empirical power law αB = b1xb2 with b2 in the range of 3 to 4. For single mode fibres, the additional loss αB depends on the optical wavelength. A maximum of αB has been found in the wavelength range around 900 nm. At this maximum, αB is larger than for multimode fibres.
