Compensation of higher-order fiber dispersion in addition to the group-velocity (second-order) dispersion (SOD) is important for 1.55 μm optical time-division-multiplexed (OTDM) communication systems utilizing subpicosecond pulses to accommodate data-rates approaching Tbit/s. Third-order dispersion of 250 fs pulses propagating at ~5 GHz over fiber-link lengths of 600 m and 2.33 km was suppressed by applying electro-optic phase modulation after temporal stretching in a dispersion compensating fiber. Numerical simulations confirm that the technique can be equally effective at >10 GHz pulse repetition rates
