Fiberoptic infrastructure a better alternative to satellite-based time transfer

March 30, 2021

Timing and synchronization are vitally important to the world around us. In most cases, signals transmitted via satellites are used to provide this service. However, satellite signals can potentially be disrupted, posing a potential threat to security and continuity.

TIMING IS EVERYTHING

Timing and synchronization are vitally important to the world around us. In most cases, signals transmitted via satellites are used to provide this service. However, satellite signals can potentially be disrupted, posing a potential threat to security and continuity. New technologies offer a solution, enabling us to arrange timing and synchronization via optical connections. These crucial services can be delivered via Eurofiber’s network. Partnering with OPNT and VSL, we aim to provide a back-up or alternative to satellite-based synchronization by routing the signals through terrestrial networks. By taking this initiative, Eurofiber and its extensive fiberoptic network make an important contribution to security and digital resilience in the Netherlands.

In modern society, we rely on infrastructure for our day-to-day lives without realizing the complexity behind it. An important requirement for many modern digital infrastructures is time or frequency synchronization. In most of these cases, GNSS satellite signals (e.g. GPS or Galileo) are used for synchronization purposes. The inconvenient truth is that this dependence on GNSS signals introduces a serious weakness in our critical digital infrastructure. If these GNSS signals were lost for whatever reason – such as satellite damage resulting from a solar storm or deliberate tampering with criminal intent – the impact of that signal loss would be incalculably massive.
