Ugolnye Kopi, Russia: Submarine Cable Landing Point

Ugolnye Kopi is an urban locality situated in the Anadyrsky District of Chukotka Autonomous Okrug, in Russia's far northeast. It lies on the eastern bank of the Anadyr River, directly across from Anadyr, the administrative center of the autonomous okrug. One submarine cable lands at Ugolnye Kopi, connecting this remote settlement to the broader domestic cable network along Russia's northeastern coastline.

The single cable serving Ugolnye Kopi is a domestic Russian link, meaning the corridor it enables is entirely within Russia rather than intercontinental or transoceanic. Given the geographic isolation of Chukotka Autonomous Okrug, this domestic submarine connection represents a significant link between the region and other parts of Russia's far eastern territories.

Cables Landing at Ugolnye Kopi

The Petropavlovsk-Kamchatsky – Anadyr cable is the sole submarine cable landing at Ugolnye Kopi. Spanning 2,173 km, it reached ready-for-service (RFS) status in 2022 on a draft basis. Both endpoints of this cable lie within Russia: one terminus is at Petropavlovsk-Kamchatsky, the capital of Kamchatka Krai, and the other is in the Anadyr area, where Ugolnye Kopi serves as the landing point. The cable links two of Russia's most remote far-eastern settlements across a considerable stretch of the North Pacific and the waters adjacent to the Chukchi Peninsula, providing a domestic submarine data corridor of significant length entirely within Russian territory.

Regional Context

Among submarine cable landing points in Russia, Ugolnye Kopi is one of the more modestly served, hosting a single cable compared to peers such as Anadyr, Ilyich, Nahodka, Petropavlovsk-Kamchatsky, and Sovetskaya Gavan, each of which serves two cables. Ugolnye Kopi shares its single-cable status only with Amderma, another Russian landing point. Its position as a landing point in the Anadyr River area, however, places it within a local cluster alongside nearby Anadyr itself, which hosts two cables.

Network Role

Ugolnye Kopi functions as a single-cable terminus rather than a multi-cable hub. Its connection via the Petropavlovsk-Kamchatsky – Anadyr cable provides a submarine data pathway between the Chukotka Autonomous Okrug and Kamchatka Krai, two of Russia's most geographically isolated far-eastern regions. The 2,173 km route is entirely domestic, serving internal Russian connectivity needs across a stretch of ocean that would otherwise separate these communities from terrestrial network options.

Within the regional submarine cable graph, Ugolnye Kopi's role is narrowly but distinctly defined: it anchors the Anadyr-area termination of one of Russia's longest purely domestic submarine cables, extending the country's subsea network into the extreme northeast of its territory.
