The dark-soliton timing jitters caused by fluctuations in either the s
oliton initial phase angle or the background amplitude when such a sol
iton propagates in a monomode optical fiber under the influence of the
stimulated Raman scattering are investigated and compared with those
that exist when the stimulated Raman scattering is not present. In add
ition, it is demonstrated that in the presence of the stimulated Raman
scattering, there exists a distance at which, for the negative solito
n initial phase angle, the dark-soliton timing jitter caused by fluctu
ations in the background amplitude becomes zero.
