NEC research and development of new submarine cable technology can increase communication speed 2.5 times
It has been reported that NEC has developed a new technology that will increase the speed of communication of submarine cables connecting national and regional information and communication networks by 2.5 times. One optical fiber can carry 34.9T bits of information in one second, equivalent to the capacity of 540 million telephone lines. It is reported that the international data traffic in the 2 years to 2 times the rapid increase in response to the rapid growth of international data traffic, NEC and strive to five years later the technology practical. Submarine cables are bundled with multiple fibers for Internet and television international broadcasts and international calls. NEC developed technology to transmit information across a distance of 6,300 kilometers across the Atlantic Ocean. Because optical communication is carried on the light wave technology and transmission, the greater the amount of light waves that can be used, the greater the transmission capacity. The NEC increases the data throughput by slightly shifting the 16 wavelengths of the same light. With the rapid popularization of smartphones, the demand for watching videos over the Internet has greatly increased, meanwhile, big data transmission among enterprises has been increasing. International data traffic increased from about 3 billion T-bits in 2012 to about 6 billion T-bits in 2014. Since 99% of international communications are transmitted through submarine cables and can not meet the demand on the existing lines alone, the relevant countries are investing more in the current deployment of optical fiber cables in the Pacific Ocean and the Atlantic Ocean. But even so, an estimated 10 years later can not meet the demand, it is necessary to expand the optical cable communication capacity.
