Tata TGN-Atlantic South

Overview

The Tata TGN-Atlantic South is a transatlantic submarine cable system connecting the United Kingdom and the United States. Spanning 6,830 kilometers, the cable has been operational since 2001 and is owned and operated by Tata Communications. As part of the global telecommunications infrastructure, the cable plays a vital role in facilitating high-speed data exchange between Europe and North America. Its deployment underscores the importance of robust, reliable undersea connections for international communications and commerce.

Designed to meet the growing demand for bandwidth in the early 21st century, the Tata TGN-Atlantic South serves as a critical link in the transatlantic corridor. This corridor is one of the busiest and most strategically important in the global internet backbone, supporting data-intensive industries, international businesses, and everyday internet users on both sides of the Atlantic. Despite its age, the cable remains a key component of Tata Communications' extensive network.

Route and Landings

The Tata TGN-Atlantic South connects two primary landing points: Highbridge in the United Kingdom and Wall Township in New Jersey, United States. These locations were strategically chosen for their proximity to major telecommunications infrastructure and their ability to support high-capacity data transmission.

Highbridge, located in Somerset, England, provides direct access to the United Kingdom's dense network of data centers and internet exchanges. This region is a gateway to Europe, enabling seamless connectivity to other parts of the continent. On the other side of the Atlantic, Wall Township in New Jersey serves as a critical landing point for submarine cables entering the United States. Its location near major metropolitan areas, including New York City and Philadelphia, ensures efficient integration with the U.S. fiber-optic backbone and access to some of the world's largest data centers.

The route of the cable crosses the North Atlantic Ocean, navigating one of the most challenging marine environments for submarine cable deployment. The cable's design and installation accounted for factors such as deep-sea topography, strong ocean currents, and the need for secure, redundant pathways to ensure uninterrupted service.

Ownership and History

The Tata TGN-Atlantic South is owned and operated by Tata Communications, a subsidiary of the Tata Group. Tata Communications is a major global player in the telecommunications industry, providing services across sectors such as finance, healthcare, and retail. The company's extensive network includes numerous submarine cables, terrestrial fiber routes, and data centers worldwide.

The cable was declared ready for service (RFS) in 2001, marking its official entry into operation. At the time, it was part of a wave of new submarine cable deployments aimed at addressing the explosive growth in internet usage and international data exchange. While specific details about the cable's current operational status or potential upgrades are not publicly available, its role as a transatlantic link remains significant in the global telecommunications landscape.

What Our Measurements Show

Our live monitoring of the Tata TGN-Atlantic South reveals performance metrics across 169 measured corridors. The best recorded round-trip time (RTT) is 6 milliseconds, while the average RTT is 89 milliseconds. These metrics reflect the cable's efficiency in transmitting data between its landing points, though they may vary depending on network conditions and traffic loads.

The measured RTT values highlight the cable's capability to support low-latency applications, which are critical for industries such as finance and media that require real-time data exchange. The performance of the Tata TGN-Atlantic South underscores its importance in maintaining reliable and high-speed connectivity between Europe and North America, even as newer systems are deployed in the region.
