The effects of wavelength separation for two wavelength division multiplexing (WDM) channels using return-to-zero pulses were examined. It was observed that for pulses shorter than 4 ps, modulated to carry data at 40 Gb/s, channels may be spaced as close as 1.8 nm, which corresponds to about 18% spectral efficiency.
