12.5 GHz spaced 1.28 Tb/s (512-channel x 2.5 Gb/s) super-dense WDM transmission over 320 km SMF using multiwavelength generation technique

We achieve a 512-channel super-dense wavelength-division-multiplexing (WDM) transmission with a 12.5 GHz channel spacing over 320 km (80 km/spl times/4) of standard single-mode fiber in the C+L-bands. Optical carrier supply modules, which are based on a flattened sideband generation scheme, are appl...

Description
Summary:We achieve a 512-channel super-dense wavelength-division-multiplexing (WDM) transmission with a 12.5 GHz channel spacing over 320 km (80 km/spl times/4) of standard single-mode fiber in the C+L-bands. Optical carrier supply modules, which are based on a flattened sideband generation scheme, are applied to generate the 512 wavelengths from only 64 distributed-feedback laser diodes with a frequency spacing of 100 GHz. Arrayed-waveguide gratings with a 12.5 GHz spacing are used in this super-dense WDM experiment.
