We present a way to improve the dispersion tolerance of an electrical-binary-signal-based duobinary transmitter, implemented by using a dual-arm Mach-Zehnder modulator driven with two complementary binary signals. Successful transmission over 200 km of single- mode fiber is achieved by optimizing the relative time delay between the binary signals and the driving voltage.
