White Rabbit Switch v3.4.

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).
