The effects of initial frequency chirp and Raman scattering on soliton-effect pulse compression are investigated. We show that Raman scattering causes a significant degradation in the compression of high-order soliton pulses. A 24% reduction is found in the compression ratio of soliton pulses of 1-ps width and order N = 15. We also show that positive chirp enhances the compression and the breakup of high-order soliton pulses, whereas negative chirp degrades the compression and retards the breakup of those pulses. These effects become more pronounced as the soliton order is increased.
