WRITE: White Rabbit for Industrial Timing Enhancement
Short Name: WRITE, Project Number: 17IND14
Type: EMPIR Call: 2018 Duration: 2018-2021
Time transfer is a scheme where multiple sites share a precise reference time. The technique is commonly used for creating and distributing standard time scales such as Universal Coordinated Time (UTC) and International Atomic Time (TAI). White Rabbit Precision Time Protocol (PTP-WR) is one of the best performing time transfer techniques. Outperforming existing capabilities, providing accurate (<200 ps), resilient and secure timing traceable to Coordinated Universal Time (UTC), it is able to exploit telecommunication fiber networks, enabling its use in widespread applications, and it is now time to exploit PTP WR as an advanced service for research and industry. This project will develop the metrological capacities required to accelerate the industrial adoption of PTP-WR, through improved hardware and calibration techniques, implemented in industrial environments.
The overall objective of the project is to demonstrate all the metrological steps necessary for the industrial adoption of PTP-WR, including improvement of the devices and the study of an effective implementation in ordinary industrial IT infrastructures without degradation of the performance of the technique compared to the results achieved in controlled research laboratories or using dedicated fiber infrastructures
