摘要：
The problem of scattering in optical fibers is approached by means of a ray theory and by considering both parameters that characterize each ray congruence. Starting from a general transport equation, a two-variable diffusion equation is derived and its field of validity is discussed. Preliminary results (steady-state power distribution among ray congruences; steady-state attenuation and steady-state length) are given in some simple but common cases. These results permit interesting comparisons with other theories.
