Yes. WRS uses standard protocols (TCP/IP, SNMP, PTPv2), making it easy to integrate with your current management and timing systems. It supports VLAN configurations and can be managed remotely via SSH or SNMP.
White Rabbit Switch by Creotech Quantum
AvailableAsk
The White Rabbit Switch (WRS) by Creotech Quantum provides sub-nanosecond accuracy and picosecond-level precision in large, distributed systems. It enables deterministic data transfer and precise timestamping—essential for scientific and industrial applications. WRS supports simultaneous time synchronization and data transmission within the same network, with inter-switch distances exceeding 10 km via fiber-optic links. Using the White Rabbit Switch, you can build networks of thousands of nodes while maintaining full stability, scalability, and the highest timing precision.

FAQ
Unlike conventional Ethernet switches, WRS supports the White Rabbit protocol, providing sub-nanosecond time synchronization. This ensures deterministic operation in distributed systems — something standard networks cannot guarantee.
No. The switch runs Linux and includes WRP and PTPv2 daemons that automatically detect nodes and manage synchronization. The management interface is user-friendly and accessible both locally and remotely.
