“…(2), our investigation of the performance differences of the test fibers must be related to this phenomenon. (2) (2) is based on a defect between the jacket and buffer, we can modify their model by assuming that the buffer coat produce certain lateral compressive force P0 per unit length on the glass fiber, with spatial frequency a, then the deformation of the glass fiber, wf, is given by in Ref.…”

“…The measurement procedure is described in the fourth section. The spatial variation of Sn(r,t) introduces a mode coupling constant according to h(t) = I k/2 JE0(r)Sn(r,t)E'(r)d2rI (2) where k is the wave number and E0 and E' are the excited and the unexcited modes, respectively. A summary and suggestion for further study are also given.…”

“…The solution is wf Posin(ax)/(EfIf)& (4) The lateral compressive force produced by the buffer shrinking due to a temperature change /.T can be approximated as [2] P0 = tbEb(T)(T)LT where tb, Eb, and a are the thickness, the Young's modulus, and the linear expansion coefficient of the buffer coat, respectively.
