This paper describes the nonsplitting condition in which a Gaussian pulse propagating down a single-mode fiber never splits into more than two peaks. This condition has not been found except for the major polarizing plane (δ = 0°) and the minor polarizing plane (|δ| = 180°), where δ/2 denotes the polarizing angle. In the present paper, it is solved over the integral of -45° ≦ δ/2 ≦ 45°. On the basis of this result, a nonsplitting condition, which is termed the comprehensive nonsplitting condition and is independent of the polarizing angle, is proposed.
