Abstract
The author numerically analyzes frequency shifts of wavelength multiplexed pico-secondoptical solitons in a fiber, where collision length is shorter than spacing between inline amplifiers.We reveal that the shifts caused by two major mechanisms: initial overlap and power lossduring the collision, can be cancelled with each other by choosing a suitable initial time offsetbetween the channels. Eye diagram calculations simulating transmission system using 3 inlineamplifiers spaced every 40km predict that the appropriate time offset minimizes the pulsearrival timing jitter.
