Transmission of 1550 nm 10 Gb/s directly modulated signal over 100 km of negative dispersion fiber without any dispersion compensation

We demonstrate the largest transmission distance (100 km) ever reported for a 10 Gb/s 1.55 /spl mu/m directly modulated signal over a single fiber link without using any dispersion compensation. The fiber is optimised for operation with directly modulated lasers and has negative dispersion.
