Abstract :
Tradeoffs between optical spectral efficiency, ASE noise-tolerance, and dispersion tolerance are investigated experimentally for three modulation formats - RZ, NRZ, and duobinary. Duobinary does not follow conventional wisdom - achieving excellent performance with the narrowest bandwidth.
