Description/Abstract

The invention of the erbium doped fibre amplifier (EDFA) has led to a revolution in telecommunications permitting data transfer at rates previously unimaginable with conventional regenerator technology. With the problem of loss largely eliminated it is now dispersion and nonlinearity that represent the principle barriers to utilizing the enormous bandwidth offered by optical fibre. Soliton transmission in which the nonlinear and dispersive effects within the fibre can be made to balance and effectively cancel provide one means of getting access to more of that potential transmission capacity. As the field has advanced further limiting issues have been identified, e.g. Gordon Haus jitter, soliton interactions, acousto-optic interactions etc., requiring more advanced solutions such as soliton control to be sought
