ACS Alaska-Oregon Network (AKORN)

ACS Alaska-Oregon Network (AKORN): Connecting Alaska and Oregon

The ACS Alaska-Oregon Network (AKORN) is a submarine cable system operated by Alaska Communications, linking Alaska to Oregon through a 3000 km fiber optic route. It connects Anchorage, Homer, Nikiski, and Florence, providing critical communication infrastructure for the region. Listed as in service since April 2009, AKORN plays a key role in Alaska’s connectivity, bridging the state to the continental United States. What makes AKORN particularly interesting is the lack of publicly disclosed technical details, such as design capacity, fiber pair count, or supplier information. This absence of transparency leaves room for speculation about its capabilities and underlying technology. Additionally, its latency characteristics, computed from physics and live internet measurements, provide a glimpse into the cable’s performance, though the full end-to-end network path includes additional delays.

Route

The AKORN cable system spans approximately 3000 km, connecting Anchorage, Homer, and Nikiski in Alaska to Florence in Oregon. Anchorage, Alaska’s largest city, serves as a major hub for the state’s telecommunications. Homer and Nikiski are smaller but strategically important towns on the Kenai Peninsula. Florence, located on the Oregon coast, provides a gateway to the continental United States. This route is significant for linking Alaska’s remote communities to the broader national and global networks.

Why it was built and what it carries

AKORN was built to improve Alaska’s connectivity with the continental United States, addressing the state’s reliance on satellite and limited terrestrial links. By providing a direct fiber optic connection, it enables faster and more reliable communication for businesses, residents, and government entities. The cable likely supports internet traffic, voice communications, and data services, though specific details about its capacity and traffic types are not publicly disclosed.

History: what can be established

The GeoCables database records AKORN’s ready-for-service date as April 2009. Publicly available industry sources do not contradict this date, nor do they provide alternative timelines. This suggests a relatively straightforward commissioning process, though detailed information about the cable’s construction, deployment, and testing phases remains unavailable.

Capacity and technology

The design capacity, fiber pair count, supplier, and technology used in the AKORN system are not disclosed in publicly available sources. Without operator documentation, attributing specific figures or characteristics would be speculative. Submarine cables typically use dense wavelength division multiplexing (DWDM) to maximize capacity, but whether AKORN employs this technology cannot be confirmed.

Latency: the physics

Theoretical calculations based on the cable’s length of 3000 km suggest a one-way light propagation latency of approximately 14.7 ms and a round-trip time (RTT) floor of 29.4 ms. However, real-world latency is higher due to additional factors such as land tails, terminal equipment, and network routing. Live latency measurements from remote probes, which represent the full internet path rather than the cable itself, show significantly higher RTTs. For example:

• Saint Petersburg to Nikiski: 193.5 ms
• Moscow to Nikiski: 175.4 ms
• Minsk to Nikiski: 168.1 ms
• Kyiv to Nikiski: 177.7 ms
• Sao Paulo to Nikiski: 171.7 ms
• Cape Town to Nikiski: 273.7 ms

These measurements reflect the complexity of global internet routing, including intermediate hops and congestion.

Redundancy: what happens if it breaks

In the event of a failure, redundancy for Alaska’s connectivity is partially supported by other submarine cables landing at shared points. Anchorage and Homer are also served by the Kodiak Kenai Fiber Link (KKFL), while Homer hosts additional cables such as Nome to Homer Express (NTHE) and TERRA SW. These systems provide alternative routes, though their capacity and geographic coverage differ. Repairing a submarine cable typically involves deploying specialized vessels to locate, retrieve, and fix the damaged section, a process that can take weeks depending on weather and logistical challenges.

Bottom line

• AKORN spans 3000 km, linking Alaska to Oregon via four landing points.
• Owned by Alaska Communications, it has been in service since April 2009.
• Technical details such as design capacity and fiber pairs are not publicly disclosed.
• Theoretical latency is approximately 29.4 ms RTT for the wet segment, but real-world measurements are higher.
• Redundancy is provided by other cables landing in Anchorage and Homer, including KKFL, NTHE, and TERRA SW.
