O. Leclerc et al., 2 x 40Gbit/s WDM optically regenerated dispersion-managed transmission over 10000 km with narrow channel spacing, ELECTR LETT, 36(1), 2000, pp. 58-59
2 x 40Gbit/s WDM regenerated, dispersion-managed transmission over transoce
anic distances is demonstrated using InP Mach-Zehnder modules. The impact o
f the channel spacing on system performance is also investigated, resulting
in error-free transmission with a channel spacing as small as 200GHz.
