The research and development of new NEC submarine cable communication technology can be 2.5 times faster

According to Reuters reports, NEC developed a new technology that can connect the information communication network between countries and regions of the sea optical cable The communication speed is increased by 2.5 times. 1 Optical fiber One can transport 34.9T bits of information, the equivalent of 540 million line capacity. It is reported that the international data The amount of communication in 2 years with the speed of 2 times increased sharply, as the rapid increase in international traffic data, NEC will strive to 5 years after the application.

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. becauseOptical communication Is equipped with the technology and transmission in the optical transmission of light, more the number of available capacity is greater. By NEC wavelength16 waves of the same slightly offset, in order to increase the amount of data transmission.

With the rapid popularization of intelligent mobile phone, via the Internet to watch more video needs, and data transmission between enterprises is also increasing. The amount of data communication between international from 2012 to approximately 3 billion T in 2014 to about 6 billion bit T bit.

As the international communication is 99% by submarine cable transmission, relying on the existing line can not meet the demand, the country is new investment, expand the 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.
