Abstract

The experimental angular aperture of step-index fibres is always smaller than the theoretical aperture. Furthermore, the light power transmitted within the fibre up to the angular aperture is the more attenuated the greater the angle of incidence is. An expression of the light power transmitted within the fibre is given, which shows that the first phenanenon is due to variations of the fibre diameter core and the second phenamenon to the cladding absorbance.
