Abstract :
The direct measurement of scattering and total losses of very good uniform optical fibres has been proposed and verified for the first time by analysing the scattering light with the variation of input launching power of an He-Ne laser by an optical attenuator. The scattered light has been detected by the cubic detector at different positions along the fibre.
