摘要：

We report transmission of 3.2-Tb/s (40 ch x 80 Gb/s) signals over 21 x 100 kin of high local dispersion-managed fiber with 0.8-b/s/Hz spectral efficiency. The test system incorporated a tandem electroabsorption modulator all-Raman amplified UltraWave fiber spans, a polarization insensitive dynamic gain equalization filter 40-Gb/s electrical time-division-multiplexing (ETDM), transmitters, a 40-Gb/s ETDM receiver, and a recirculating loop. The dispersion map was designed to minimize the impairment caused by optical nonlinearities.
