The extinction coefficient, used to express losses in optical fibres due to absorption and diffusion, fluctuates in time with a 1/f spectrum. The authors have measured fluctuations in the intensity of light propagating through optical fibres. Noise measurements as a function of fibre length show that the noise is not due to fluctuations in reflectivity at the ends. The relative noise in the intensity of the transmitted light is proportional to fibre length
