✦ Synopsis
By combining optical time.division-multiplexing (TDA4) and wavelength division-multiplexing (WDM) with a single super-continuum light source NTT Corp. has successfully conducted an ultra-fast, large-capacity optical transmission experiment at 400 Gbitls (equivalent to sending 100 years of newspapers in a second) over a distance of 1 O0 km. Having already confirmed that the PLL timing extraction circuit and all optical time-division demultiplexer are able to
function at 400 Gbitls and 200 Gbitls, respectively, NTT plans to continue R&D efforts to develop an optical transmission system exceeding 1 T bitls.
