Production of ultra-low-noise White Rabbit switchesWe upgraded WR with a low jitter daughterboard and a phase locked oscillator. This way time and frequency are transferred in a stable way from a single reference clock to multiple clients in a wide-area fibre-optic network.Read more... |

Enhancement of White Rabbit technologyWe adapted WR to enhance data bandwidth for large amounts of data that will be produced by instruments like SKA and CTA. More than 500 Mb/s of reliable data throughput was achieved while synchronizing over the same network to a fraction of a nanosecond.Read more... |

Towards a precise timing system for the Cherenkov Telescope ArrayWe did a setup of a hierarchical WR network to get a high relative timing precision between different telescope cameras. We used 32 WR timing nodes to mimic 32 CTA telescopes.Read more... |

Testing White Rabbit hardware in field conditions in SiberiaMany instruments are in remote locations and operate under harsh conditions, such as extreme temperatures and drought. A good place to study the stability of WR hardware in long-term exposure to harsh conditions is Siberia.Read more... |

A new, simple, tool for faster transport of large data setsThe currently used network protocol (TCP) stems from a time when data files were small and collaborations were not as global as today. A new tool using another protocol (UDP) was written to allow for faster transport of large data sets.Read more... |
