2015: From nonlinear noise model towards record working distances of fiber-optical communication links

2015-record-distances-fiber-communications-EN.jpg

MSU physicists together with their colleagues from NSU, T8 and OFS companies developed a model of forming and accumulation of nonlinear interferometric noises in fiber-optical coherent communication systems. This model has been experimentally verified and used for improvement of the existing coherent optical communication systems. The record distance achieved for non-regeneration information transfer in surface communications lines is up to 6000 km for trasferring of 80 spectral channels each of 100 Gb/s with the total capacity of 8 Tb/s.
