SYNCHRONISATION SYSTEM Russian patent published in 2018 - IPC H04J1/00 

FIELD: data processing; optics.

SUBSTANCE: invention relates to synchronisation means and can be used in time synchronisation systems using an optical fibre line for communicating a synchronizing object with a synchronised object. For this purpose, system comprises an optical fibre line, the first end of which through a controlled delay unit is connected to the output-input of an optical connector, the unidirectional output of which through an optical amplifier is connected to the input of an optical splitter, the first output of which through the optical combiner is connected to the unidirectional input of the optical connector. Second output of the optical splitter is connected to the input of the first opto-electronic converter, the output of which, through a unit for isolating characteristic pulses, is connected with the signal input of an error detector. Output of the error detector via a control signal driver is connected to the control input of the controlled delay unit. Reference input of the error detector is connected to the output of the time scale driver, which is also connected to the input of the trigger pulse driver, the output of which through the opto-electronic converter is connected to the second input of the optical combiner. Synchronised object comprises a unit for forming direct and reflected signals optically connected to the other end of the fiber-optic line, the direct signal output of which through a second opto-electronic converter is connected to the input of the synchronising pulse forming unit.

EFFECT: technical result consists in creating a synchronisation system based on the principle of transferring the actual synchronising pulses to the synchronised object over a fibre optic communication line.
