FIELD: radio engineering, communication.SUBSTANCE: apparatus has factory lengths of optical cable, the optical fibres of which are connected in series in connectors and have chromatic dispersion of the same sign. Optical amplifiers are connected in series into the optical fibres such that the distance between the optical amplifiers is broken down into elementary sections. High-nonlinearity optical fibres, circulators and variable period Bragg diffraction gratings are further included for dispersion compensation. The connectors are further fitted with holders in a housing made of heat-insulating material. An elementary section includes a connector, having a holder with a high-nonlinearity optical fibre, a circulator and a Bragg diffraction grating. Optical radiation power at the output of the optical amplifiers and the distance between them, the length of an elementary section, parameters of the high-nonlinearity optical fibre and variable period Bragg diffraction gratings for dispersion compensation are selected depending on parameters of optical fibres of factory lengths of the optical cable such that dispersion-controlled solitons propagate in the transmission line.EFFECT: wider field of use.1 dwg |
