the White Rabbit
A shared sense of time changes what’s possible. White Rabbit brings sub-nanosecond and satellite independent synchronisation to your devices — and keeps the technology open for everyone.
Open Source
Design available to everybody
< 1 ns
Synchronisation accuracy
>1000 km

White Rabbit extends Ethernet with precise timing and deterministic data delivery—so distributed systems can act as one.
From research labs to real-world systems.
Born at CERN and developed with a global community, White Rabbit supports demanding timing applications in science and beyond. The collaboration brings users, developers and industry together to keep the technology moving forward.
MEMBERS OF THE COLLABORATION
A network built by its members.
White Rabbit connects research organisations, industry and specialist technology companies around a shared, open timing standard.
Keep the conversation going
Good timing takes a community.
