Dikson, Russia: Submarine Cable Landing Point

Dikson is a port town situated on the Kara Sea at the mouth of the Yenisei Gulf, on Russia's Arctic Ocean coast, in the Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. It stands as one of the world's northernmost settlements on a continental mainland, making it a distinctly remote location for submarine cable infrastructure. One submarine cable lands at Dikson, connecting it to other points along Russia's northern coastline.

The cable landing here — Polar Express — operates entirely within Russian territory, forming a domestic connectivity corridor along the Arctic coast. This positions Dikson as a waypoint in an intra-Russian submarine cable route rather than an intercontinental or international link. Despite its small population of 319 as recorded in the 2021 Census, Dikson's geographic situation on the Arctic shore gives it a particular role in extending submarine cable reach into one of the world's most remote maritime environments.

Cables Landing at Dikson

Polar Express is a submarine cable with a total length of 12,650 km, with a ready-for-service (RFS) date of 2022 on a draft basis. The cable connects landing points exclusively within Russia, running along the Arctic coast and linking Dikson to other Russian endpoints. At 12,650 km, Polar Express is a long-distance domestic cable, reflecting the vast geographic scale of Russia's northern coastline. Dikson serves as one of the intermediate or terminal landing points on this Arctic routing.

Regional Context

Among Russia's 28 submarine cable landing points, Dikson hosts one cable, placing it alongside Amderma as one of the single-cable landing points in the country. By comparison, landing points such as Anadyr, Ilyich, Nahodka, Petropavlovsk-Kamchatsky, and Sovetskaya Gavan each host two cables, giving them broader connectivity within Russia's submarine cable network. Dikson's position reflects the more limited but geographically significant role that Arctic waypoints play in extending domestic submarine infrastructure.

Network Role

Dikson functions as a single-cable terminus on the Polar Express system, contributing to Russia's domestic Arctic submarine cable corridor. The landing here extends submarine connectivity along Russia's northern Arctic coastline, a region where overland alternatives are limited by extreme geography and climate. Polar Express, at 12,650 km, represents a long national route, and Dikson's inclusion as a landing point demonstrates the cable's reach into some of Russia's most isolated Arctic communities.

As a single-cable landing point in a country with 13 submarine cables spread across 28 locations, Dikson occupies a specialized position in Russia's broader submarine cable map — one defined not by cable density but by the geographic extremity it brings within reach of the national network.
