Abstract

Synchronization systems over optical fibre infrastructure with femtosecond precision in terms of jitter and long-term stability are reviewed and their usage in telecommunications and physics measurements is introduced. The designed electro-optical synchronization system makes use of commercial telecom single-mode optical fibre operating at 1550 nm. It consists of an electro-optical transmitter, located near a low-jitter master radiofrequency oscillator, and an opto-electrical receiver located at a remote location. Both units are connected with a commercial single-mode optical fibre, connected in a loop-back to achieve phase-drift compensation.
