Abstract :
A straight-line 160-Gb/s 1000-km differential phase-shift keying transmission was successfully demonstrated with time-domain optical Fourier transformation (OFT) without employing polarization multiplexing or Raman amplification. The OFT greatly reduced the transmission impairments caused by linear perturbations, and transmission performance close to the amplified spontaneous emission limit was achieved.
