The duration of an optical signal is defined as the time interval in which a certain part of its energy is contained. It has been proved that under such definition the form of a signal with a given duration and maximum length of dispersion broadening is not Gaussian. Time profile of such signals has been obtained as a superposition of orthogonal symmetric Hermitean modes. Such signals have also been shown to be smooth functions of time. Furthermore, it has been shown that the expansion converges rapidly and is considerably well represented by the first few modes.
