Abstract
We demonstrate transmission of 170-Gb/s single- and alternating-polarization return-to-zero differential phase-shift keying signals in a recirculating loop using dispersion-managed fiber spans and all-Raman amplification. In the single polarization case, bit-error-ratio (BER) values of 5 x 10(-9) and 1.6 x 10(-4) were obtained after 960 and 2880 km, respectively. In the alternating polarization case, significantly larger transmission distances were achieved, with BER values of 2 x 10(-9) after 1920 km and 5 x 10(-5) after 4320 km, respectively.
