A new undersea fiber-optic cable linking Japan and Russia went into service this week providing the first direct link between the two countries and an alternate cable route between Europe and Asia.
The Hokkaido-Sakhalin Cable System (HSCS) runs between the two islands, Japans Hokkaido and Russias Sakhalin, and has a capacity of 640G bps (bits per second). Construction of the 570 kilometer cable was carried out by Japans NTT Communications and Russias TransTeleCom Company and started and completed last year.
Until now traffic between Japan and Russia, which share a sea border in the Russian Far East, had to run via traditional cable routes through Southeast Asia and the Indian Ocean to Europe.
