Alcatel lucent's well-known research institutions at bell LABS has developed a breakthrough in the field of optical communication technology for long distances, could significantly inhibit the nonlinear effect of noise. It is reported, bell LABS is through the "digital interference" the latest optical signal modulation technology.
Bell laboratories in the field of optical fiber communication has a profound accumulation, had developed the world's leading optical communication technology for many times. The development of the optical signal modulation technique can effectively restrain fiber nonlinear effect of transmission capacity. According to the results of the test is currently in a 8 wavelength multiplexing on 12800 kilometers of fiber optic cable transmission capacity of 406.6 Gbps.
Submarine cable used in long distance optical communication technology, on the single fiber transmission capacity is gradually approaching
