Introduction: According to foreign media reports, NEC developed technology, the speed of communication cable connection information communication network between countries and regions increased to about 3.5 times.
Submarine cable is a plurality of optical fiber bundle for the Internet and television broadcast international and international calls. The development of NEC technology to transmit information across a distance of 6300 kilometers between the Atlantic. because Optical communication Is equipped with the technology and transmission in the optical transmission of light, more the number of available capacity is greater. By NEC wavelength 16 waves of the same slightly offset, increase the amount of data transmission.
With the rapid popularization of intelligent mobile phone, through the Internet to watch the video of the situation increased, in addition to large data transmission between enterprises is also increasing rapidly. In 2012 about the amount of international data communication between 3 billion terabit to 14 years to about 6 billion bit too.
As the international communication between the 99% is by submarine cable transmission, relying on the existing line can not meet the demand, has been the emergence of new investment, cable operations in the Pacific and the Atlantic. But even so, 10 years later also can not meet the demand, so it is necessary to expand the capacity of communication cable.
