FIELD: information technologies.
SUBSTANCE: information data streams are broken into blocks of fixed size, so called clusters, which are coded by special optical signals in the form of optical pulses following each other. The number of pulses in groups may differ, within a group each pulse is characterised by its individual wavelength of optical radiation. Coding optical signals are combined into frames, accompanied with marker optical pulses with a fixed wavelength of optical radiation, different from wavelengths of coding optical signals. Frames are sent along a fibre optic track. At a receiving end of the fibre optic track return conversions take place, information data streams are restored in their initial form.
EFFECT: higher noise immunity and reliability of transferred information, lower requirements to an optic fibre of a fibre optic track, higher speed of data transfer, higher protection of transferred information.
