The three factors that determine spectral efficiency
For many fibre applications, spectral efficiency is a key performance criterion. This white paper focuses on why spectral efficiency matters, how the relationship between wavelength capacity-reach and spectral efficiency has changed, and the three key factors determining spectral efficiency.
