Analysis of timing jitter for a wavelength‐division‐multiplexed dispersion‐managed optical soliton transmission system

Abstract

In a wavelength-division-multiplexed optical soliton transmission system, collisions of solitons between different channels induce frequency shifts and time shifts of the signal which result in undesirable timing jitter. The residual frequency shift after collision can be reduced by managing the dispersion value periodically along the line. In this paper, we theoretically show a mechanism of the collision-induced frequency shift and time shift for a dispersion-managed line. We also analyze the collision-induced timing jitter and Gordon–Haus jitter simultaneously and propose an optimal path averaged dispersion of the line with respect to minimum timing jitter. © 2001 Scripta Technica, Electron Comm Jpn Pt 1, 84(10): 10–15, 2001
