Optical soliton communication in a positively andnegativelydispersion-allocated optical fibre transmission line

A bright optical soliton described by a nonlinear Schrödinger equation can survive even in a positive dispersion region as long as the average dispersion has a negative value. T...

10 Gbit/s pseudorandom dark soliton data transmissionover 1200 km

A 10 Gbit/s pseudorandom (PR) dark soliton data signal has been successfully transmitted over 1200 km for the first time. The dark soliton source was a 1.53 µm DFB LD and was mo...
