Hokkaido-Sakhalin Cable System Starts Commercial Operations

July 4, 2008

TransTeleCom, a Russian backbone telecommunications operator, and NTT Communications, a provider of IP solutions, has announced that the Hokkaido-Sakhalin Cable System, which directly links the two companies’ telecom networks via an undersea cable between Nevelsk, Sakhalin in Russia and Ishikari, Hokkaido, Japan, began commercial operation on July 3, 2008.

The two companies jointly started to construct the fiber-optic submarine cable Hokkaido-Sakhalin Cable System (HSCS) in 2007 and the work was completed in December 2007.

The HSCS measures 570 km in length and has a capacity of 640 Gbps. Its startup gives NTT Com the shortest route between Japan and Europe, compared with existing cable routes through southern Asia and the United States, by connecting the cable to the TransTeleCom’s (TTK’s) extensive backbone network in Russia, which exceeds 55,000 km.

The HSCS route will enable NTT Com to provide additional offering in Arcstar Global Leased Line Service utilizing the new route and taking orders starting on July 3, 2008. It is estimated to shorten the latency within the company’s backbone by 20 to 30% compared to the existing routes.

The HSCS route will be added to the backbone of NTT Com’s secure, scalable Arcstar Global IP-VPN Service (MPLS) beginning August 2008. The HSCS route will be added to NTT Com’s global IP Tier 1 network covering Asia-Pacific Europe and North America, with connection to major ISPs worldwide, beginning on July 3, 2008.
