Description

This report presents the findings of the Long-Haul White Rabbit Incubator project, evaluating the deployment of a high-accuracy time service using White Rabbit technology over long-haul optical DWDM networks. Tests were performed in both the laboratory and the field. The results are presented and analysed, based on which a cost-benefit analysis is provided. The report concludes with best-practice recommendations designed to guide NRENs in selecting the most effective architecture for their synchronisation needs.
