Vladivostok, Russia: Submarine Cable Landing Point

Vladivostok is the largest city of Primorsky Krai and the administrative center of Russia's Far Eastern Federal District, situated on the Sea of Japan along the Golden Horn Bay. Its position on Russia's Pacific coast, close to the borders of both China and North Korea, places it at a geographically significant point on the eastern edge of the Russian landmass. One submarine cable currently lands at Vladivostok, connecting the city to Russia's broader submarine cable infrastructure.

The cable serving Vladivostok is the Polar Express, a domestically routed system that links multiple points within Russia. As a single-cable landing point on the Sea of Japan, Vladivostok serves as a terminus in an intra-Russian submarine cable corridor, supporting connectivity along Russia's Pacific and Arctic-facing coastlines.

Cables Landing at Vladivostok

Polar Express is a submarine cable with a total length of 12,650 kilometers, reaching its ready-for-service date in 2022 on a draft basis. The cable connects multiple landing points exclusively within Russia, making it an entirely domestic system. With Vladivostok as one of its endpoints, Polar Express extends across a considerable span of Russian territory, linking the Far Eastern city into a national submarine cable network. At 12,650 kilometers, it is notably longer than the Russian average cable length of approximately 5,002 kilometers, reflecting the vast geographic distances involved in connecting Russia's far-flung coastal communities.

Regional Context

Among Russia's 24 submarine cable landing points, Vladivostok hosts one cable, placing it in the same tier as Amderma, which also has a single cable landing. The majority of Russia's other Pacific and Arctic coastal landing points — including Nahodka, Sovetskaya Gavan, Petropavlovsk-Kamchatsky, Ilyich, and Anadyr — each host two cables, giving them a somewhat broader degree of submarine cable connectivity. Vladivostok's single-cable status positions it in the lower range of Russian landing points by cable count, though it remains integrated into the national system through the long-distance Polar Express route.

Network Role

Vladivostok functions as a single-cable terminus in Russia's domestic submarine cable network, connected exclusively through the Polar Express system to other Russian landing points. The cable's 12,650-kilometer length underscores the scale of the intra-Russian corridor it supports, spanning Pacific and potentially Arctic coastal regions within one continuous system. As a terminus rather than a multi-cable hub, Vladivostok does not serve as a junction point between competing routes, but instead anchors one end of a long domestic link.

Within the broader Russian submarine cable graph, Vladivostok represents the integration of one of the country's most significant Far Eastern urban centers into a nationally focused undersea network, extending domestic submarine connectivity to a city positioned at the intersection of Russia's Pacific coast and its proximity to Northeast Asia.
