Synchronization and Coexistence in Quantum Networks
Authors: Ivan A. Burenkov, Alexandra Semionov, Hala, Thomas Gerrits, Anouar Rahmouni, DJ Anand, Ya-Shian Li-Baboud, Oliver Slattery, Abdella Battou, and Sergey V. Polyakov Abstract: We investigate the coexistence of clock synchronization protocols with quantum signals in a common single-mode optical fiber. By measuring optical noise between 1500 nm to 1620 nm we demonstrate a potential for…

RELIABILITY IN A WHITE RABBIT NETWORK
Autors: Maciej Lipinski, Javier Serrano, Tomasz Włostowski, CERN, Geneva, SwitzerlandCesar Prados, GSI, Darmstadt, Germany Abstract: White Rabbit (WR) is a time-deterministic, low-latency Ethernet-based network which enables transparent, subns accuracy timing distribution. It is being developed to replace the General Machine Timing (GMT) system currently used at CERN and will become the foundation for the control…

White Rabbit: Sub-Nanosecond Timing Distribution over Ethernet
Authors: Pedro Moreira, Javier Serrano, Tomasz Wlostowski – Beams Department, CERN, Geneva, SwitzerlandPatrick Loschmidt, Georg Gaderer, Institute for Integrated Sensor Systems, Austrian Academy of Sciences, Wiener Neustadt, Austria Abstract: White Rabbit (WR) is the project name for a ambiguous project that uses Ethernet as both, deterministic (synchronous) data transfer and timing network. The presented design…

White Rabbit Precision Time Protocol on Long-Distance Fiber Links
Authors: Erik F. Dierikx; Anders E. Wallin; Thomas Fordell; Jani Myyry; Petri Koponen; Mikko Merimaa Abstract: The application of White Rabbit precision time protocol (WR-PTP) in long-distance optical fiber links has been investigated. WR-PTP is an implementation of PTP in synchronous Ethernet optical fiber networks, originally intended for synchronization of equipment within a range of 10 km. This paper discusses…

White-Rabbit-enabled Data Acquisition System
Authors: José López-Jiménez, Miguel Jiménez-López, Javier Díaz – University of Granada, Granada, SpainJosé Luis Gutiérrez-Rivas – Seven Solutions, Granada, Spain Abstract: This work examines the feasibility of using Ethernet-based time transfer methods based on White Rabbit technology to discipline all the clock domains of a networked data acquisition system (DAQ). Existing systems provide synchronization capabilities,…

White Rabbit-Based Time Distribution at NIST
Authors: J. Savory, J. Sherman, and S. Romisch – Time and Frequency Division, National Institute of Standards and Technology, Boulder, CO 80305 Abstract: The National Institute of Standards and Technology (NIST) produces a real-time realization of UTC(NIST) which is used to contribute to Coordinated Universal Time (UTC) and as a source for accurate time in…

White Rabbit: a PTP Application for Robust Sub-nanosecond Synchronization
Authors: Maciej Lipinski, Tomasz Włostowski, Javier Serrano, Pablo Alvarez – CERN, Geneva Abstract: This article describes time distribution in a White Rabbit Network. We start by presenting a short overview of the White Rabbit project explaining its requirements to highlight the importance of the timing aspects of the system. We then introduce the technologies used…
