Beaufort

Overview

The Beaufort submarine cable is a 38-kilometer fiber-optic link connecting Ireland and the United Kingdom. Scheduled to be ready for service in 2027, this cable is designed to enhance the digital infrastructure between the two nations. Despite its relatively short length, the Beaufort cable plays a critical role in supporting data transmission and ensuring connectivity between these neighboring countries. Its strategic placement reflects the growing demand for reliable and high-capacity communication channels in the region.

Both Ireland and the United Kingdom are integral to Europe’s telecommunications landscape. Ireland serves as a gateway for trans-Atlantic cables, while the UK hosts major internet exchange points. The Beaufort cable aims to bolster these roles by providing a direct, low-latency route that complements existing systems and supports the increasing reliance on cloud services, digital communications, and data-intensive applications.

Route and Landings

The Beaufort cable connects Kilmore Quay in Ireland to Newgale in the United Kingdom. Kilmore Quay, located in County Wexford, is a small coastal village known for its fishing heritage. Its strategic location on Ireland’s southeastern coast makes it an ideal landing point for submarine cables, offering proximity to both the UK and other European markets. The choice of Kilmore Quay reflects Ireland’s role as a critical hub for international data traffic, particularly for routes bridging Europe and North America.

On the UK side, the cable lands in Newgale, a village in Pembrokeshire, Wales. Newgale’s position on the southwestern coast of Wales provides a direct and geographically efficient connection to Ireland. The route crosses the southern Irish Sea, a relatively shallow body of water that facilitates the deployment and maintenance of submarine cables. This direct link enhances connectivity between the two countries, bypassing more congested routes and ensuring robust data transmission capabilities.

Ownership and History

The Beaufort submarine cable is jointly owned by Amazon Web Services (AWS) and Vodafone. AWS, a global leader in cloud computing, and Vodafone, a major telecommunications provider with extensive operations across Europe, have partnered to develop this critical infrastructure. Their collaboration underscores the importance of the cable in meeting the demands of modern digital ecosystems, including cloud services, enterprise connectivity, and consumer internet usage.

Although the cable is not yet operational, its planned launch in 2027 aligns with ongoing efforts to expand and modernize Europe’s telecommunications networks. The Beaufort cable is expected to play a key role in enhancing regional connectivity, particularly as data traffic continues to grow. Its development reflects broader trends in the industry, where partnerships between technology and telecommunications companies are increasingly common to address the challenges of global data transmission.

What Our Measurements Show

Our live monitoring of the Beaufort cable, conducted across 18 measured corridors, indicates promising performance metrics. The best recorded round-trip time (RTT) is 33 milliseconds, while the average RTT across all measurements is 75 milliseconds. These figures highlight the cable’s potential to deliver low-latency connections, which are critical for applications such as video conferencing, online gaming, and cloud computing.

The relatively short length of the Beaufort cable contributes to its low latency, as shorter cables generally experience less signal degradation and fewer delays. This makes the Beaufort cable a valuable asset for both Ireland and the UK, particularly as they continue to expand their digital infrastructure and support growing demands for high-speed, reliable connectivity. The cable’s performance is expected to enhance the overall resilience and efficiency of the regional telecommunications network.
