White Rabbit

White Rabbit provides sub-nanosecond accuracy and picoseconds precision of synchronization for large distributed systems. It also allows for deterministic and reliable data delivery.White Rabbit allows you to precision time-tag measured data and lets you trigger data taking in large installations while at the same time using the same network to transmit data.sub-nanosecond synchronizationconnecting thousands of nodestypical distances of 10 km between nodesEthernet-based gigabit rate reliable data transferfully open hardware, firmware and softwaremulti-vendor commercially produced hardwareContactMaciej LipinskiTagsDocumentation White RabbitLatest NewsJob opportunity at CERN: FPGA developerFeb 9, 2026CERN is looking to recruit an FPGA and hardware designer to work on White Rabbit switch v4.

It is a WR node whose jitter (integrated between 100Hz and 20MHz) is less than 100 femtoseconds, the most precise WR node I know of, originally designed by Mattia Rizzi and Tomasz Włostowski.
