Telstra Endeavour

Overview

The Telstra Endeavour is a submarine cable system that spans 9125 kilometers, providing a critical intercontinental link between Australia and the United States. Operational since 2008, it is owned and operated by Telstra, one of Australia's largest telecommunications companies. The cable plays a vital role in facilitating high-speed data transmission across the Pacific Ocean, supporting both regional and global connectivity. Its design and deployment underscore the importance of robust infrastructure in maintaining seamless communication between two major economies.

This cable is part of the trans-Pacific corridor, a key route for international communications that connects Oceania with North America. By offering a direct fiber-optic connection, Telstra Endeavour enhances the speed and reliability of data transfer, serving as a backbone for internet, business, and personal communications. It also provides redundancy and resilience to the broader network of submarine cables in the Pacific region.

Route and Landings

The Telstra Endeavour connects two landing points: Keawaula, located on the island of Oahu in Hawaii, United States, and Paddington, a suburb in Sydney, New South Wales, Australia. These locations were strategically chosen to link major hubs of telecommunications and commerce in both countries. Keawaula serves as an entry point to the extensive U.S. network, while Paddington is a gateway to Australia's domestic and international connectivity infrastructure.

The cable traverses the vast expanse of the Pacific Ocean, one of the most challenging environments for submarine cable deployment due to its depth and seismic activity. The route ensures a direct connection between the two continents, bypassing intermediate locations to minimize latency. This direct path is particularly significant for businesses and service providers that rely on low-latency, high-capacity connections for critical operations. The Pacific crossing also highlights the engineering feats required to lay and maintain cables in such a demanding environment.

Ownership and History

Telstra is the sole owner of the Telstra Endeavour cable system. As a telecommunications company with roots dating back to 1879, Telstra has played a pivotal role in shaping Australia's communication landscape. The deployment of the Telstra Endeavour in 2008 marked a significant milestone in the company's efforts to expand its international reach and enhance connectivity between Australia and the United States.

The cable was developed during a period of rapid growth in global internet usage and increasing demand for high-capacity international links. It was designed to complement existing trans-Pacific systems, providing additional capacity and redundancy. The launch of the Telstra Endeavour reinforced Australia's position as a key player in the global telecommunications network and demonstrated Telstra's commitment to investing in infrastructure that supports economic and technological growth.

What Our Measurements Show

Our live monitoring of the Telstra Endeavour cable system has identified 152 measured corridors along its route. These measurements provide insights into the cable's performance, including latency and reliability. The best round-trip time (RTT) recorded is 139 milliseconds, while the average RTT is 219 milliseconds. These figures reflect the cable's efficiency in transmitting data across the Pacific Ocean, a distance that inherently introduces latency due to the vast geographical span.

The performance metrics highlight the cable's capability to support high-speed, low-latency communications, which are essential for applications such as financial transactions, cloud computing, and real-time communications. The monitoring data also underscores the importance of maintaining and optimizing submarine cable systems to ensure consistent performance and reliability. By providing a direct link between Australia and the United States, the Telstra Endeavour continues to play a crucial role in supporting global connectivity and data exchange.
