Complete White Rabbit Architecture

Together, the Open Time Node WR and Open Time Source WR form a scalable, end-to-end White Rabbit timing solution. Deployed as a synchronized system, they enable sub-nanosecond synchronization from the core to the edge of your infrastructure.

Example Deployment

  • At the core: The Open Time Source WR distributes White Rabbit and PTP signals throughout the network.

  • At the edge: Open Time Node WR units receive the White Rabbit timing stream and output frequency references (10 MHz, PPS) to local systems.
    This architecture delivers deterministic, traceable timing for distributed infrastructures—no GNSS at the edge required.

Triple-Clock Validation

It’s not enough to take time from one source. The Open Time Appliance runs a real-time clock quorum algorithm, cross-checking multiple references to eliminate bad data and prevent drift.

Real-time Drift & Spoof Detection

If a time source starts to drift, the Open Time Appliance detects the anomaly and rejects bad data before it ever affects your network.

If a GPS signal is spoofed, it flags and corrects the error—keeping your system secure and accurate.

Clock Quorum Technology

The power of 3, because precision needs proof.

The Open Time Appliance, has built in clock quorum technology, not only for resilience but to evidence the synchronisation capabilities.
Too many devices on the market claim precision with little in the way of testing capabilities, our systems provide raw evidence with clear metrics and comparisons through a concenses mesh.

Low on Space & Power

With all 3 units only taking up 1RU of 19" rack space. You no longer need to sacrifice expensive datacentre space and power resources for gold standard timing.All of our units fit the same form factor, which means even a rubidium device is capable of being deployed in even the most space constrained environments.

Resilience and Redundancy

Tripple modular redundancy provides the most robust and resilient system. This is not only fault tolerant but also enhnaces synchronisation capabiities.The Open time appliance is a low cost solution to tripple modular redundancy as purchasing 3 units is typically less than 2 units from our competitors.

<5ns Accuracy and Precision

Flagship solutions integreated into all of our models from Ublox allow these devices to be accurate to less than 5 nanoseconds to UTC.

With advanced features for anti-jam and anti-spoof counter measures these units maintain accuracy and precision even during sub-optimal conditions

Frequency Generation

From OCXO to high-end atomic rubidium and low-swap caesium

It must use a single-board computer that is deployed in millions of units for the best reliability
It must run the same Timebeat software that works so well everywhere already.
