An efficient wavelength-conversion-free all-optical 2R regenerator is proposed. The regeneration is based on power-dependent spectrum broadening in normal-dispersion fiber and subsequent off-centered filtering. Twofold regeneration is performed in a bidirectional configuration where the signal is transmitted twice along the fiber in opposite directions. Experiment at 10Gb/s shows no penalty arising from the bidirectional highpower signal transmission in the fiber and demonstrates strong improvement of extinction ratio of the input signal by the regenerator.
