DEVICE FOR ORGANIZATION OF DISTILLATION COMMUNICATION AND METHOD OF ORGANIZATION OF DISTILLATION COMMUNICATION (EMBODIMENTS) Russian patent published in 2020 - IPC H04B10/25 

FIELD: physics.

SUBSTANCE: invention relates to automatics, communication and can be used on railway transport for arrangement of overflight and communication with emergency recovery place. To this end, each end station has a two-fibre SFP module for signal communication, wherein signal reception and signal transmission are provided by separate sockets. Fibre-optic communication line comprises 1+n pairs of optical fibres of the main fibre-optic cable and 1+n optical switch blocks. Each hauling access unit comprises two two-fibre SFP modules, a switch, a power supply and a talk-back device. Each unit of optical switches is connected to power supply source of each hauling access unit, besides, when power supply is not available on the distillation access unit, the signal passes in transit by the off-line access unit switched off from power supply. Each switch is configured to relay received linear signal with its subsequent transmission, as well as input and output of information. Device for arranging the distillation communication is designed so that when the signal passes from left to right, the signal goes through one of a pair of main fibre-optic cables, and when the signal passes from right to left, the signal is different.

EFFECT: technical result consists in improvement of the overhaul operation efficiency.
