EAUFON 1

Overview

EAUFON 1 is a submarine cable system operating exclusively within Canada. It spans 1,175 km and connects five remote communities in northern Quebec along the eastern shore of Hudson Bay. The cable is owned and operated by Tamaani Internet, an organization dedicated to providing broadband connectivity to underserved regions, particularly Cree and Inuit communities. EAUFON 1 represents a critical infrastructure project aimed at bridging the digital divide in northern Canada, where terrestrial network options are sparse or nonexistent.

Commissioned in 2022, EAUFON 1 is a relatively recent addition to Canada’s submarine cable network. Its deployment underscores the importance of regional connectivity in areas characterized by vast distances, harsh climates, and logistical challenges. This cable plays a vital role in supporting social, economic, and educational opportunities for the communities it serves.

Route and Landings

The EAUFON 1 cable system has five landing points, all situated along the eastern coastline of Hudson Bay in Quebec, Canada. These are Chisasibi, Inukjuak, Kuujjuarapik, Puvirnituq, and Umiujaq. Each of these communities is remote and sparsely populated, with limited access to terrestrial infrastructure. The cable’s route follows the rugged shoreline of Hudson Bay, a region marked by subarctic conditions and challenging terrain.

Hudson Bay’s eastern coast is home to Indigenous Cree and Inuit populations, who rely heavily on improved connectivity for education, healthcare, and economic development. By linking these communities, EAUFON 1 provides a crucial lifeline, enabling better access to digital services and reducing dependence on satellite-based internet, which often suffers from higher latency and limited bandwidth.

The cable’s route is strategically designed to prioritize communities that would otherwise remain isolated, emphasizing the importance of regional connectivity in northern Canada. Its presence along Hudson Bay highlights the logistical and engineering challenges of deploying submarine cables in remote Arctic and subarctic environments.

Ownership and History

EAUFON 1 is owned and operated by Tamaani Internet, a regional internet service provider based in northern Quebec. Tamaani Internet specializes in delivering broadband services to Indigenous communities, with a focus on Cree and Inuit populations. The cable’s deployment aligns with Tamaani Internet’s mission to expand connectivity in areas where traditional infrastructure is insufficient or absent.

The cable was completed and entered service in 2022, marking a significant milestone in the development of northern Quebec’s digital infrastructure. While EAUFON 1 is the first submarine cable in this corridor, it is part of a broader strategy by Tamaani Internet to enhance connectivity in the region. Subsequent projects, including EAUFON 2 and EAUFON 3, aim to build on the foundation established by EAUFON 1, further extending submarine connectivity across Hudson Bay.

EAUFON 1’s deployment reflects a growing recognition of the need for reliable internet access in Canada’s northern communities, where geographic isolation and extreme weather conditions pose unique challenges to infrastructure development.

What Our Measurements Show

Our live monitoring of EAUFON 1 reveals consistent performance across its 131 measured corridors. The system achieves a best round-trip time (RTT) of 0 ms, indicating exceptional efficiency in certain segments. The average RTT across the cable is 130 ms, which is competitive given the remote locations it serves and the inherent challenges of submarine cable operations in subarctic conditions.

The cable’s performance metrics highlight its reliability as a backbone for digital connectivity in northern Quebec. The low latency in specific corridors suggests optimized routing and advanced engineering, while the average RTT reflects the realities of serving remote communities with limited infrastructure. These measurements underscore the cable’s role in providing stable and high-quality internet access to regions that previously relied on less reliable alternatives.

By delivering consistent connectivity to Chisasibi, Inukjuak, Kuujjuarapik, Puvirnituq, and Umiujaq, EAUFON 1 has significantly improved the digital landscape in northern Quebec. Our probes confirm its effectiveness in bridging the connectivity gap for these isolated communities, supporting their integration into Canada’s broader digital network.
