ABSTRACT:
An apparatus includes a driving voltage generator that generates a pulse driving voltage having a rising edge and a decaying edge. An optical modulator produces a first pulse at the rising edge of the pulse driving voltage and a second pulse at the decaying edge of the pulse driving voltage. Therefore, the first and second pulses are both produced from a single driving pulse voltage. The frequency of the first pulse is determined by the slope of the rising edge of the pulse driving voltage and the frequency of the second pulse is determined by the slope of the decaying edge of the pulse driving voltage. The first and second pulses are transmitted through a transmission line. A detection device detects the first and second pulses after being transmitted through the transmission line. A processor then determines the amount of dispersion in the transmission line by comparing the time interval between the detected first and second pulses to the time interval of the first and second pulses before being transmitted. Generally, the optical modulator is a Mach-Zehnder modulator driven with a pulse driving voltage exceeding the half-wavelength voltage of the modulator.
