Triple-wavelength-band WDM transmission technologies

This paper first described design guidelines of multi-wavelength-band WDM transmission systems that avoid the degradation caused by inter- and intra-wavelength-band nonlinear interactions. The guidelines indicate the best combination of wavelength bands for realizing triple-wavelength-band WDM transmission. After discussing the performance of multi-wavelength-band WDM transmission systems, a 1000-channel WDM carrier generator was demonstrated for realizing advanced triple-wavelength-band WDM transmission systems.
