In this study we examine the physical mechanism that prevents the use of sh
ort optical pulses in high bit-rate transmission systems. Continuum-induced
soliton-soliton interaction is the cause of long-range as well as enhanced
direct soliton-soliton interaction. We show, by means of a purely analytic
al approach, that solitan-continuum interaction causes position wiggling of
the soliton and that when this effect is applied to a random sequence of s
olitons it becomes an additional cause of timing jitter. (C) 1999 Optical S
