We have transmitted 10 Gb/s data over 130 km standard fiber without any dispersion penalty in receiver sensitivity (for 10/sup -9/ BER) and with a 7% eye margin for 10/sup -15/ BER by operating an integrated EA/DFB laser with low extinction ratio (/spl epsi/=5 dB) and negative chirp (/spl Delta//spl nu/=-0.01 nm).
