EN The study proposes the structure of construction and technical implementation of an optical operational storage device based on fiber-optic lines for optical computers. The basic element is a ring-type storage device on fiber-optic lines, in which information circulates as a wave packet of optical pulses along a closed fiber circuit. The operating range of 1550 nm is used to reduce optical losses. Using NZDSF fiber of the SMF-LS type is justified to compensate for the polarisation mode dispersion. An SOA amplifier is used to restore the optical signal level. An electro-optical directional splitter is used to input/output optical signals. To work with optoelectronic memory on fiber-optic lines, it is recommended to use a femtosecond fiber laser and the wave-coding method. The study found that using fiber-optic lines can increase the speed of information flow up to ten times by reducing the time spent on the RAM operation.
