3.08 Tb/s (77 × 42.7 Gb/s) Transmission over 1200 km of Non-zero Dispersion-Shifted Fiber with 100-km Spans using C- and L-Band Distributed Raman Amplification

Abstract

With the increasing demand for transmission capacity on optical fiber trunk lines, ultra-long 40Gb/s per-channel all optical transmission systems are now becoming very attractive [1-3], as they offer high signal spectral efficiency and large capacity with a smaller number of channels, at potentially lower cost.
