White Rabbit Switch v3.4.
The key element of the White Rabbit network
WR Switch
It is the first commercial available device developed with the White Rabbit (WR) Technology. It distributes Time and Frequency within a sub-nanosecond accuracy to thousands of nodes through standard optical fiber over Metro Area network distances. It also works as a basic data switch. It is the basic element for scientists and technologists looking for experimenting with WR technology and to evaluate features like deterministic time transfer or dynamical self-calibration of optical fiber links.
- Deterministic time distribution with accuracy 1 ns.
- Long distances (hundreds of Kms).
- Many hops (14 tested keeping subnanosecond accuracy).
- Subnanosecond accurate event timestamps (ps for Ethernet traffic).
- Dependable: redundant network topologies.
- High scalability.
- Heterogeneous timing interface (PTP, NMEA, etc).
Advantages
Sub Nano Second Time Accuracy
With less than a billionth of a second of accuracy compared to a master reference clock, the White Rabbit Time Distribution products provide you with ultra precise synchronization.
Timing Over Fiber Optic Cabling
With the ability to connect devices using fiber optic cables, White Rabbit timing distribution products enable you to transfer time information at a sub-nano second level – both in Local Area Networks (LAN), Wide Area Networks (WAN) and across large distances.
USE CASES
-
Status of the uTCA Digital LLRF design for SARAF Phase II
One of the crucial control systems of any particle accelerator is the Low Level Radio Frequency (LLRF). The purpose of a LLRF is to control the amplitude and phase of the field inside the accelerating cavity.
-
Status of the uTCA Digitizer BPM design for SARAF Phase II
One of the crucial monitoring systems of any particle accelerator is the Beam Position Monitor (BPM). The purpose of a BPM is to provide information on the position, phase and current of the beam along the accelerator line.

Pico Second Timing for High Energy Facilities
Timing systems are used for providing a common notion of time to all the elements of the facility as well as for the generation of discrete triggering events and periodic signals needed by the various elements. In addition, it also can be used for radio frequency dissemination across the whole facility.
