TransTeleCom Ltd. (TTC) and NTT Communications have successfully completed construction of the Hokkaido-Sakhalin Cable System (HSCS) submarine cable. The cable's purpose is to directly connect Russian and Japanese telecommunications systems on the Nevelsk-Ishikari route and to provide global companies and carriers with access to TransTeleCom's transcontinental Eurasia Highway - what TransTeleCom says is the most efficient data transit route between European and Asian countries.
The 570-km-long cable system is based on DWDM technology and has a capacity of 640 Gbps. NEC was selected as general contractor for construction of HSCS. To ensure reliability and increase system security, the cable was buried up to 1 meter deep in the seabed along the entire route.
Comprehensive testing of the system is currently underway. First a seven-day segment test will be conducted, following by a five-day load test. After successful testing, TTC, NTT, and NEC will sign a trilateral acceptance certificate, which will attest to the system's technical preparedness.
The report of the acceptance board and issue of permits is expected in January 2008. Operations will follow shortly.
HSCS is a joint project of TransTeleCom Ltd. (TTC) and NTT Communications Corporation (NTT Com), Japan's largest telecommunications company. Cable construction agreement was signed by TTC and NTT Com in February 2007 during Prime Minister Mikhail Fradkov's visit to Japan. HSCS is amongst the largest joint projects in the history of Russian-Japanese economic relations. The new route meets the growing requirements of multinational corporations for data transmission services; it will become the shortest seamless high-speed telecommunications system connecting Russia and Japan. HSCS will also become a part of an alternative transcontinental highway for data delivery from Europe to Asia. Previously, routes via Indian and Pacific Oceans were primarily used for data exchange between Europe and Asia, the company's said in a statement.
NTT Com and TTC earlier signed an Internetworking Agreement and a Memorandum of Understanding for the purposes of joint development of the IP transit business, mutual provision of MPLS-based services, provision of international private lines, and voice traffic exchange.
