In this study, we experimentally characterize optical short-pulse transmission through single-mode fibers. The initial pulses were precisely generated by an optical pulse synthesizer. The optical pulse synthesizer provides line-by-line phase and intensity modulations to individual channels in optical frequency combs and generates precise arbitral pulses. Pulse shaping enables the experimental evaluation of pulse transmission along the fibers under various initial pulse conditions, and the pulse evolution of Gaussian and sech2 pulses through standard single-mode fibers (SMFs) was experimentally investigated. The sech2 pulses had smaller pulse broadening and distortion than the Gaussian ones at the same pulse width and peak power. The sech2 pulses nearly maintained their initial time bandwidth products (TBPs). The required pulse peak power for soliton transmission matched the theoretical value.
