Optical system for transfer of timing reference

摘要

The present invention relates to an optical system for transfer of timing reference signal and radio frequency synchronisation of multiple events with femtosecond precision on multiple remote locations such as within a particle accelerator, where synchronisation scheme with a low phase jitter and a long term stability is required using standard telecommunications single-mode optical fibre. Said system comprises a transmitter (1), a low jitter oscillator (2) and a receiver (3), said transmitter (1) and said receiver (3) being connected by means of a transmission optical line (4) and a return optical line (5).
