Anadyr, Russia

Anadyr: Submarine Cable Landing Point

Anadyr is a port town and the administrative center of Chukotka Autonomous Okrug, situated at the mouth of the Anadyr River at the tip of a peninsula that protrudes into Anadyrsky Liman, in Russia's far northeast. As the easternmost town in Russia, it occupies a remote position on the country's Pacific-facing coastline. Two submarine cables land at Anadyr, making it a notable node in Russia's expanding high-latitude and Far Eastern cable network.

Both cables landing at Anadyr connect to other points within Russia, placing this landing point firmly within a domestic connectivity corridor. One of the cables, Polar Express, spans 12,650 km and represents one of the longer submarine systems serving Russian territory. The other, Petropavlovsk-Kamchatsky – Anadyr, provides a more regional link across 2,173 km. Together, these two systems connect Anadyr to other Russian landing points, extending fiber connectivity into one of Russia's most geographically isolated regions.

Cables Landing at Anadyr

Polar Express is a 12,650 km submarine cable system that reached ready-for-service status in 2022, with a draft designation. It connects landing points within Russia, and its considerable length reflects its role in spanning vast distances across Russian territory, likely traversing the country's northern or far eastern coastal geography. Anadyr is one of the endpoints on this system.

Petropavlovsk-Kamchatsky – Anadyr is a 2,173 km submarine cable that also achieved ready-for-service status in 2022, with a draft designation. As its name indicates, the cable links Anadyr with Petropavlovsk-Kamchatsky, another Russian port city on the Kamchatka Peninsula. This cable provides a direct connection between two of Russia's prominent Far Eastern coastal communities, both of which share the same two-cable landing point status.

Regional Context

Within Russia's submarine cable infrastructure of 28 landing points, Anadyr is one of several locations hosting two cables, alongside Ilyich, Nahodka, Petropavlovsk-Kamchatsky, and Sovetskaya Gavan. It hosts more cables than Amderma and Dikson, each of which serves a single cable. Russia's submarine cable network encompasses 13 cables in total, with an average cable length of 4,510 km, and its first cable entered service in 2000.

Network Role

Anadyr functions as a two-cable landing point within an entirely domestic submarine cable corridor, receiving both long-haul and regional fiber connections that terminate in Chukotka Autonomous Okrug. The Petropavlovsk-Kamchatsky – Anadyr cable establishes a direct inter-regional link between two Far Eastern Russian communities, while Polar Express integrates Anadyr into a significantly longer domestic route. Both cables entered service in 2022, meaning Anadyr's submarine cable infrastructure is entirely of recent origin.

As a port town in one of Russia's most remote and sparsely connected regions, Anadyr's position as a two-cable landing point places it among a peer group of similarly equipped Russian coastal nodes. Its inclusion in both a long-distance system and a dedicated regional link reflects the expansion of submarine cable connectivity into Russia's northeastern extremities, extending the national fiber graph to its easternmost town.
