Abstract. The article is devoted to the development of a precision optical signal scaling device intended for use as an element for assigning weighting factors in fiber-optic digital-to-analog data converters. An analysis of the metrological characteristics of existing optical attenuator designs is given. Requirements for the accuracy of optical signal weighting factor scaling devices used in amplitude fiber-optic digital-to-analog data converters are formulated. The design of a fiber-optic device that combines the functions of a two-count precision attenuator and an optical signal switch is considered. A description of the design and operating principle of the device containing channels for coarse and fine adjustment of the optical signal attenuation coefficient is given. The results of numerical modeling of the attenuator attenuation coefficients in the coarse and fine channels for various parameters of the optical and geometric parameters of the device, as well as the general adjustment characteristic, are presented. The possibility of creating an optical signal scaling device with a relative error in setting the attenuation coefficients no worse than.

Keywords: converter, attenuator, switch, design, attenuation coefficient.
