Abstract :
In this paper, we review recent advances in undersea 100G system research with high spectral efficiency and large capacity. Several different techniques are covered including spectral shaping, Nyquist wavelength division multiplexing, orthogonal frequency division multiplexing, optical superchannel, tight optical filtering with multisymbol detection using maximum a posteriori probability or maximum likelihood sequence estimation, and coded modulation. In particular, we review several recent experiments transporting >; 10 Tb/s with >; 3 b/s/Hz spectral efficiency over transoceanic distance.
