Transmission performance of a 10-Gb/s integrated EA/DFB laser has been evaluated in terms of the eye margin degradation and the receiver sensitivity penalty caused by the chromatic dispersion in the standard (non-DSF) fiber. Combination of low extinction ratio (ε = 5 dB) and negative chirp (Δυ = -0.01 nm) operation allows 10-Gb/s transmission over 130-km standard fiber without any dispersion penalty in receiver sensitivity (for 10-9 BER) and with a 7% eye margin for 10-15 BER.
