First, the relation between the dispersion of the fiber and the propagation constant and equivalent refractive index is presented.
文章先给出了光纤色散与光纤传播常数及等效折射率的关系。
Then, the dispersion of the multi-clad fiber is obtained by solving the propagation constant and the equivalent refractive index of single-clad fiber which is equal to multi-clad fiber.
