ABSTRACT:
The data transmission rate link length product of monomode fiberguide telecommunication systems can be increased above values possible in "linear" systems by appropriate use of the non-linear dependence of the fiber refractive index on electric field. In particular, selecting the appropriate pulse peak power and center wavelength can result in creation of a soliton, i.e., a pulse capable of substantially dispersionless transmission. The center wavelength is to be close to, but larger than, the wavelength of zero first-order chromatic dispersion of the fiberguide, and the latter wavelength is to be within the anomalous dispersion regime of the fiberguide. Criteria for determining the appropriate peak power, center wavelength, fiber loss, and minimum link length, as well as the asymptotic pulse width and soliton spread due to the power loss in the fiber are given, and facilitate design of a system according to the invention.
