This paper introduces research trends in terabit-per-second (Tb/s) Wavelength Division Multiplexing (WDM) optical transmission technologies that will be indispensable for constructing a next-generation ultra-highcapacity trunk network. First, technologies for improving the WDM spectral efficiency and increasing the optical amplifier bandwidth are introduced in order to increase the total WDM capacity. Then related optical device technologies are briefly introduced, especially ones for fabricating WDM light sources. Finally, technical challenges towards Tb/s transmission over distances of 10, 000 km are mentioned, including RZ pulse-based WDM transmission.
