Port Alsworth, AK: A Remote Hub in Alaska's Connectivity Chain

Port Alsworth, Alaska, may seem an unlikely spot for submarine cable infrastructure, but its role in the TERRA SW cable network highlights the importance of connectivity in remote regions. Nestled in the Lake and Peninsula Borough, 165 miles southwest of Anchorage, this small community of 186 residents (as of 2020) serves as one of 11 landing points for the TERRA SW cable, which has been operational since 2012.

The TERRA SW Cable: Stitching Together Alaska's Remote Communities

Unlike major landing points in the United States such as Boca Raton, FL, or Hermosa Beach, CA, which host multiple international cables, Port Alsworth is part of a domestic chain. The TERRA SW cable exclusively serves the United States, connecting Port Alsworth to other remote Alaskan communities like Iliamna, Pedro Bay, and Williamsport. This cable is not a gateway to international networks but rather a lifeline for regional connectivity, enabling these isolated towns to communicate and share resources more effectively. Port Alsworth’s role in this chain is significant due to its geographic isolation. The community lies deep in Alaska’s wilderness, far from urban centers, and relies on air travel for most transportation. The TERRA SW cable ensures that residents and businesses here can access the internet and other digital services, linking them to Anchorage and beyond via regional and national networks.

Latency Measurements: A Window into Performance

GeoCables’ monitoring of the TERRA SW cable provides unique insights into its performance. With 25 completed latency checks from nine source cities, Port Alsworth’s average round-trip latency stands at 173 ms, with the best observed latency at 132 ms. These numbers are notable for a remote landing point, demonstrating the effectiveness of the cable in bridging vast distances across Alaska’s rugged terrain.

Port Alsworth in Context

The United States hosts 113 submarine cables across 160 landing points, with an average cable length of 4,957 km. Port Alsworth, with its single cable, ranks in the top 69% of landing points by cable count. While it may not match the scale of major hubs like Kapolei, HI, or San Juan, PR, Port Alsworth’s inclusion in the TERRA SW network underscores the importance of connecting smaller, remote communities.

Conclusion

Port Alsworth’s role in Alaska’s connectivity landscape is a testament to the value of regional submarine cable networks. While larger landing points in the United States serve as gateways to international connectivity, Port Alsworth exemplifies how domestic cables like TERRA SW can transform isolated communities. By linking Port Alsworth to other Alaskan towns and the broader national network, this cable ensures that even the most remote areas are part of the digital age.
