    Alternative Spectral Window for Precise Time Fibre Based Transport

  • Original language description

    Precise time and also stable frequency transfers are approaching the state to become almost standard applications for optical fiber networks, especially they are becoming supported in multiple research and education networks. In principle, the time and frequency transfers are not possible to be implemented over data transport layer, which hasn&apos;t been was designed for essential stability, and thus dedicated wave band is required for such implementation. To achieve even better stability for precise time and stable frequency, the bidirectional transmission in single physical medium (fibers and ideally all components along the route) is preferred. The White Rabbit system combines synchronous Ethernet and Precise Time Protocol (IEEE-1588) and it has been designed in the CERN with the aim to provide time synchronization among large number of sensors, actuators and other devices utilized in experiments. Primary aim was the operation over single fiber (to avoid nonreciprocal changes in directions) using standard telecommunication transceivers designed for single fiber operation with reach limited to about 40 km. In this paper, we experimentally verify and compare stability of White Rabbit system operation over long distances up to 300 km using active optical amplification on wavelengths which should not be utilized within spectrum needed for regular data transmissions.
