A novel technique is presented for obtaining the amplitude and phase of optical pulses in a time extent range from few ps up to, approximately, 1ns. The method which is based on properties of the Wigner Distribution Function (WDF) only requires, for a practical realization, of passive optical communication components. Simulations are carried out for testing the method performance considering both, realizable models of the involved devices and typical pulses found in optical transmission systems. This numerical analysis allows to explore the practical feasibility, range of operation and the limitations imposed by the mismatch and/or variation of the device parameters. The technique is also compared to another pulse characterization method
