摘要： A long haul, broadband DWDM system that has been optimized by the proper selection of the distribution of total dispersion compensation. Dispersion compensation is utilized at both the receiver and tranmitter ends. System performance is dependent on the ratio of compensation split between the transmitter and the receiver. A system operated in the nonlinear regime can be compensated to operate with low BER and with reduced penalties due to residual dispersion effects, even when the spread of total accumulated dispersion between the extreme channels in a broadband system exceeds 1,100 ps/nm.
