Taking into account the higher order dispersions of the complex propagation constant involving its loss term, the equation of a Gaussian pulse propagation is derived for a single-mode optical fiber, by which the pulse-peak intensity, the pulse-width, the pulse-delay time and the skewness can be readily estimated along the fiber length. Then, among various combinations of the dispersion profile between the loss and the phase terms including both normal and anomalous dispersions, two typical cases of the pulse-broadening and narrowing are numerically shown, in which possibility of the compression is especially discussed with the combination of the sharp anomalous absorption-band and the normal phase-dispersions.
