The World developement of submarine system fiber optic cable
 

Asia-Europe submarine cable system west of the United Kingdom, by connecting the Mediterranean France, Italy and other countries, through the Red Sea into the Indian Ocean to Singapore, then east through Malaysia, the Philippines, Vietnam, arrived in China last Mastery Japan, South Korea. It is about 38,000 km, connecting 33 countries and regions, a total of 39 landing stations. Asia-Europe submarine cable systems in our Shanghai, Shantou, each with a landing station. 

 

In China,Submarine cable as an important means of contemporary international communications, responsible for 90% of international traffic, is the main carrier of the global information and communication. China's optical fiber business is a new high-profit growth.

Our submarine cable system construction is the biggest problem submarine systems integration issues. At present, the international market using submarine construction general contractor-mode communication device, cable manufacturers and construction units to work together, and our submarine construction using compartmentalization split mode, conduct pre-feasibility studies and circuit design by the Institute and operators, by submarine cable submarine cable and accessories manufacturers, construction units by the submarine cable laying, and then by the owner or operator of system integration. This model is not conducive to the integration of systems integration capabilities, is not conducive to the formation of one or two strong submarine systems integrators, but not conducive to China to the international submarine cable system.

Undersea fiber optic cable production technology mainly dedicated fiber optic submarine cable manufacturing, dedicated submarine optical laser welded stainless steel pipe manufacturing unit, the inner layer steel wire armored, seamless copper tube manufacturing, extruded insulation layer, the outer layer of steel wire armor, outer layer is PP rope and asphalt manufacturing.
