Solas

Overview

The Solas submarine cable is a regional fiber-optic system linking Ireland and the United Kingdom. Spanning a total length of 232 kilometers, the cable has been operational since 1999. It is jointly owned and operated by Vodafone and eir, two prominent telecommunications companies. Solas provides a direct and reliable data transmission route between the two countries, playing a vital role in regional connectivity and telecommunications infrastructure.

Designed to support high-speed data transfer, Solas enhances the efficiency of communication networks in both Ireland and the United Kingdom. Its strategic placement contributes to the redundancy and robustness of the broader European and trans-Atlantic cable systems. The cable is a key component of the digital infrastructure in the region, facilitating seamless communication for businesses, governments, and individual users alike.

Route and Landings

The Solas cable connects two landing points: Kilmore Quay in Ireland and Oxwich Bay in the United Kingdom. Kilmore Quay, located on Ireland's southeastern coast, is a small fishing village in County Wexford. Its proximity to the Irish Sea makes it a practical location for submarine cable landings, offering a direct route to the United Kingdom. Oxwich Bay, situated on the southern coast of Wales, is part of the Gower Peninsula, an area known for its natural beauty and coastal accessibility. This location provides an optimal landing point for connecting to the UK's terrestrial fiber-optic networks.

The undersea route of the Solas cable crosses the Irish Sea, a body of water that has historically served as a critical link between Ireland and Great Britain. The relatively short distance between the two landing points minimizes latency and ensures efficient data transmission. By connecting these specific locations, the Solas cable integrates seamlessly into the existing network infrastructure of both countries, supporting local and international connectivity.

Ownership and History

The Solas cable is co-owned by Vodafone and eir, two major players in the telecommunications industry. Vodafone operates globally, providing mobile and fixed broadband services across multiple continents. Eir, based in Ireland, is a leading provider of telecommunications services, including voice, data, and broadband. The collaboration between these two companies ensures the cable's operational reliability and integration into their broader service offerings.

Commissioned and made ready for service in 1999, Solas represents a significant investment in regional connectivity. At the time of its deployment, the cable addressed the growing demand for high-capacity data links between Ireland and the United Kingdom. Over the years, it has continued to serve as a critical component of the telecommunications infrastructure in the region, supporting both primary data traffic and redundancy for other systems.

What Our Measurements Show

Our live monitoring of the Solas cable provides valuable insights into its performance. The cable is divided into 23 measured corridors, allowing for detailed analysis of its operational efficiency. The best recorded round-trip time (RTT) across the cable is 11 milliseconds, with an average RTT of 12 milliseconds. These figures indicate a low-latency connection, which is crucial for real-time applications such as video conferencing, online gaming, and financial transactions.

The consistent performance of the Solas cable underscores its importance as a reliable link between Ireland and the United Kingdom. By maintaining low latency and high data transfer rates, the cable supports a wide range of services for both residential and commercial users. Its role in regional connectivity is further enhanced by its integration into the broader European and trans-Atlantic cable networks, ensuring seamless communication across continents.
