Abstract :
Wide wavelength-band (1535-1560 nm and 1574-1600 nm) 28×10 Gbit/s WDM transmission over a 320 km dispersion-shifted fibre, using both conventional and gain-shifted EDFAs, is successfully demonstrated. This is achieved by employing two techniques to suppress the various nonlinear effects that depend on chromatic dispersion values: unequal channel spacing for 1550 nm band signals and dispersion pre-compensation for the 1550 and 1580 nm bands
