Nome to Homer Express (NTHE): connecting Alaska's remote communities
The Nome to Homer Express (NTHE) is a 1,545-kilometer submarine cable system owned by Quintillion, designed to link several remote communities in Alaska. With landing points in Nome, Homer,
Emmonak,
Hooper Bay,
Igiugig,
Naknek,
Pile Bay, and
Williamsport, the cable provides essential connectivity across a challenging and sparsely populated region. Listed as in service, its recorded ready-for-service (RFS) year in the GeoCables database is 2027, though it is unclear whether this date reflects the actual operational timeline or a planned milestone.
Several aspects of the NTHE remain uncertain due to limited public disclosures. Key technical parameters, such as design capacity, fiber pair count, supplier, and specific technology, are not documented in available sources. This lack of transparency makes it difficult to assess the full scope of the cable's capabilities or its role within Alaska's broader telecommunications infrastructure.

Route
The NTHE connects eight landing points across Alaska, spanning from Nome in the northwest to Homer in the south-central region. The cable's route traverses remote and rugged terrain, including coastal and inland areas. Each landing point serves as a hub for local connectivity, enabling broadband access for communities that have traditionally faced challenges in securing reliable telecommunications services.
The cable intersects with other submarine systems at several locations:
- Homer:
ACS Alaska-Oregon Network (AKORN),
Kodiak Kenai Fiber Link (KKFL),
TERRA SW
- Nome:
Quintillion Subsea Cable Network
- Igiugig, Pile Bay, and Williamsport: TERRA SW
These intersections provide opportunities for redundancy and expanded connectivity within Alaska's network infrastructure.
Why it was built and what it carries
The NTHE was built to address the connectivity needs of Alaska's remote communities, many of which rely on satellite or microwave links that are often less reliable and more expensive than fiber-optic solutions. By providing high-speed, low-latency connectivity, the cable aims to improve internet access, support local businesses, and enable critical services such as telemedicine and online education.
While the cable's specific data-carrying capacity is not disclosed, its role as a regional connector suggests that it is designed to handle significant traffic volumes, particularly for underserved areas.
History: what can be established
The GeoCables database lists the NTHE's ready-for-service year as 2027, but this date may reflect either the actual operational timeline or a planned milestone. Publicly available information does not confirm whether the cable was completed earlier or delayed. If industry sources suggest a different RFS year, the discrepancy could arise from factors such as phased deployment, delayed permitting, or updates to project timelines.
Quintillion, the cable's owner, is known for its focus on improving connectivity in Alaska. The company also operates the Quintillion Subsea Cable Network, which connects Nome to other parts of the state and international networks.
Capacity and technology
The design capacity, fiber pair count, supplier, and specific technology used in the NTHE are not disclosed in public sources. Without operator documentation, attributing these parameters would be speculative. The cable's performance and scalability remain unknown, although its purpose suggests it is engineered to meet the demands of Alaska's remote communities.
Latency: the physics
Theoretical one-way light propagation over the NTHE's 1,545 km wet segment is approximately 7.6 milliseconds, with a round-trip time (RTT) floor of 15.1 milliseconds. However, real-world latency is higher due to additional factors such as land tails, terminal equipment, and routing.
Live measurements from remote probes show significantly higher RTT values for internet paths terminating in Hooper Bay:
- Kyiv -> Hooper Bay: min 177.6 ms, avg 180.2 ms
- Sao Paulo -> Hooper Bay: min 171.6 ms, avg 171.7 ms
- Minsk -> Hooper Bay: min 161.9 ms, avg 162.1 ms
- Cape Town -> Hooper Bay: min 275.1 ms, avg 278.7 ms
- Almaty -> Hooper Bay: min 242.3 ms, avg 242.7 ms
- Moscow -> Hooper Bay: min 171.7 ms, avg 172.7 ms
These values reflect the full internet path, including terrestrial and routing delays, rather than the cable's isolated performance.
Redundancy: what happens if it breaks
The NTHE is part of a broader network that includes connections to other submarine cables, such as the ACS Alaska-Oregon Network, Kodiak Kenai Fiber Link, TERRA SW, and the Quintillion Subsea Cable Network. These systems provide redundancy and alternative routes in the event of a cable failure.
Standard industry practices for submarine cable repair include fault localization, deployment of cable ships, and splicing or replacement of damaged segments. Repairs in Alaska's challenging environment may be complicated by weather, ice conditions, and the remote nature of the landing points.
Bottom line
- The Nome to Homer Express (NTHE) spans 1,545 km, connecting eight landing points in Alaska.
- Owned by Quintillion, the cable is listed as in service, with a recorded RFS year of 2027.
- Key technical details, including design capacity and fiber pair count, are not disclosed.
- Theoretical RTT over the wet segment is approximately 15.1 ms, but real-world latency is higher due to routing and terrestrial factors.
- The cable intersects with other systems, providing redundancy and expanded connectivity.
