LONG-DISTANCE 40-GBIT S SOLITON TRANSMISSION OVER STANDARD FIBER BY USE OF DISPERSION MANAGEMENT/

We demonstrate, through numerical simulations, the possibility of tran smitting solitonlike pulses over 2000 km of standard fiber at a single -channel data rate of 40 Gbits/s. The system used here employs a novel dispersion map to overcome the large fiber dispersion. The longest tr ansmission distance was achieved with pulses that did not exhibit the enhanced energy normally associated with dispersion management and ind eed had lower energy than an equivalent average soliton.
