FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication engineering and can be used in systems with predistortion. The apparatus includes a module for establishing correspondence, a module for obtaining corrected information and a module for calculating parameters. The dynamic adjustment method includes: creating table of correspondence of elements using the module for establishing correspondence; when information on a plug-in board in the optical transmission device is corrected, obtaining corrected information on the plug-in board by the module for obtaining corrected information and transmitting the corrected information to the module for calculating parameters; as well as re-calculating, by the module for calculating parameters, of the overall length of the transmission line between interconnected boards in accordance with the corrected information on the plug-in board and the table of correspondence of elements, and then re-calculating values of predistortion and alignment parameters in accordance with the overall length of the transmission line and types of microcircuits of the interconnected boards and sending notification on values of predistortion parameters.EFFECT: high noise-immunity owing to notification of each board on predistortion.9 cl, 4 dwg, 5 tbl |
