Nonlinear Transmission Characteristics of DWDM Coherent Optical Signal through Multiple Dispersion-Shifted Fiber Spans

摘要

We show theoretically that, unlike intuitive prediction, 100 Gbps DWDM coherent optical signal such as DP-16QAM can safely be transmitted through long-length DSF in most probable practical conditions. This is attributable to self-suppression of four-wave mixing effect of 100Gbps class signal.
