Installation of telecommunications has an optical waveguide a low spread of glass.

摘要

An optical waveguide for use in an optical communication system employing a broad spectral source. Mode coupling is present in the propagation of optical signals in the waveguide, and the parameters of the waveguide are such that pulse dispersion produced by the finite spectral width of the source is minimized by utilizing the mode coupling to substantially cause cancellation of dispersion which is linear with respect to waveguide length and which is caused by the mode independent material dispersion and by the mode dependent waveguide dispersion.
