Abstract

Limitation of the transmission rate in optical soliton high bit rate (5 Gbits/s and higher) and ultralong (up to 10,000 km) information transmission systems is mainly due to soliton timing jitter, which is concerned with interaction of solitons with the spontaneous noise of optical amplifiers (Gordon-Haus effect)¹ and electrostrictional soliton long-range interaction.² The methods of the soliton timing jitter suppression were proposed.^3,4 Similar problems arise when teraherz sequence of subpicosecond solitons have to be transmitted through long fibre of up to 100 km length. In this paper we propose the original method of the timing jitter suppression of subpicosecond solitons. The method is based on the soliton frequency stabilization due to the joint action of differential spectral amplification of soliton and Raman self-frequency shift.
