We demonstrate, by numerical simulation, the possibility of 160-Gb/s single channel transmission over distances >8000 km with no active control using short-period dispersion-managed fiber, in the absence of polarization-mode dispersion (PMD). The performance of this system is limited by the growth of continuous-wave background instabilities, resulting from strong filtering, and the accumulation of jitter. However, when introduced, the effects of PMD become the dominant limiting factor.
