What each country and landing point keeps if Petropavlovsk-Kamchatsky - Anadyr goes down. A calculation from our cable and landing-point database, not a forecast.
Every landing point of this cable has another cable within 50 km.
No alerts from our monitoring on this cable in the last 180 days. Events feed →
Counted: other international cables landing in the same country (domestic cables between points of one country are not a way out), other cables at landing points within 50 km, and whether the country has land links. Not counted: cable capacity, operator contracts and satellite. Use as a first look at dependence, not as a statement of what would happen.

About the Petropavlovsk-Kamchatsky - Anadyr Cable System
The Petropavlovsk-Kamchatsky - Anadyr submarine cable is a fiber-optic telecommunications link spanning 2,173 kilometers across Russia's Far East. Owned by Rostelecom, the cable connects Petropavlovsk-Kamchatsky on the Kamchatka Peninsula, Anadyr in Chukotka, and Ugolnye Kopi, a nearby locality. It is listed as in service and was recorded as ready for service in 2022, according to GeoCables data.
What makes this cable particularly interesting is its route through some of the most remote and sparsely populated regions of Russia, where telecommunications infrastructure is limited. While its technical specifications, such as design capacity and fiber pair count, remain undisclosed, the cable plays a key role in improving connectivity for these isolated areas. However, due to the lack of publicly available data, many aspects of its technology and performance remain uncertain.
The cable connects three landing points: Petropavlovsk-Kamchatsky on the Kamchatka Peninsula, Anadyr in Chukotka, and Ugolnye Kopi, which is near Anadyr. These regions are characterized by their remote geography, harsh climate, and sparse population. Petropavlovsk-Kamchatsky serves as a key hub for Kamchatka, while Anadyr is the administrative center of Chukotka. Ugolnye Kopi, a locality close to Anadyr, adds redundancy to the landing configuration. The cable traverses the Pacific Ocean and the Bering Sea, areas known for their challenging underwater terrain and seismic activity.
Why it was built and what it carries
The Petropavlovsk-Kamchatsky - Anadyr cable was built to enhance connectivity in Russia's Far East, a region with limited terrestrial infrastructure and high dependency on satellite communications. By providing high-speed, low-latency fiber-optic connectivity, the cable supports internet access, telecommunication services, and potentially government and private sector operations in these remote areas. Rostelecom, as the owner, likely uses the cable to extend its network reach and improve service reliability in Chukotka and Kamchatka.
History: what can be established
GeoCables data records the cable as ready for service in 2022. No conflicting dates have been identified in publicly available industry sources, although the absence of detailed documentation makes it difficult to verify this timeline independently. Rostelecom's involvement aligns with its broader strategy of expanding telecommunications infrastructure in Russia's underserved regions.
Capacity and technology
The design capacity, fiber pair count, supplier, and specific technology used in the cable have not been disclosed in public records. Without operator documentation, attributing these parameters would be speculative. It is reasonable to assume that the cable employs standard modern fiber-optic technology, but the absence of detailed specifications limits further analysis.
Latency: the physics
The computed one-way light propagation latency for the cable's wet segment is approximately 10.7 milliseconds, with a theoretical round-trip time (RTT) floor of 21.3 milliseconds. This calculation assumes light traveling through fiber at speeds between 200,000 and 204,000 km/s. However, real-world latency is higher due to additional factors such as land tails, terminal equipment, and routing inefficiencies.
Live measurements from remote probes show significantly higher RTTs, such as 223.2 ms from Moscow to Ugolnye Kopi and 225.6 ms from Saint Petersburg to Ugolnye Kopi. These values reflect the full internet path, including terrestrial routing and network congestion, rather than the cable's performance alone.
Redundancy: what happens if it breaks
If the Petropavlovsk-Kamchatsky - Anadyr cable were to experience a fault, redundancy in the region would depend on alternative infrastructure, such as the Polar Express cable, which also lands at Anadyr and Petropavlovsk-Kamchatsky. Repairs to submarine cables in this corridor would follow standard industry practices, including fault localization, deployment of cable ships, and replacement or splicing of damaged sections. The remote and harsh environment of the Far East could pose logistical challenges for repair operations.
Bottom line
The Petropavlovsk-Kamchatsky - Anadyr cable spans 2,173 km and connects three landing points in Russia's Far East.
Owned by Rostelecom, it is listed as in service and recorded as ready for service in 2022.
Technical specifications such as design capacity, fiber pairs, and supplier are not publicly disclosed.
Computed latency for the wet segment is approximately 21.3 ms RTT, but live internet path measurements show higher values.
Redundancy in the region includes the Polar Express cable, which shares landing points with this system.
