Abstract(in Japanese) (See Japanese page)
Abstract(in English) Motivated by the rapid increase in global data traffic, ultrahigh-speed transmission with a single-channel bit rate exceeding 1 Tbit/s has become an important research target. We have proposed ultrafast OTDM transmission using optical Nyquist pulse and recently realized single-channel transmission at 10~15 Tbit/s. By virtue of a narrow spectral width, Nyquist pulses have larger tolerance to chromatic dispersion and polarization-mode dispersion compared with RZ pulses.These features are excepted to be advantageous not only for achieving an extremely high bit rate such as 10 Tbit/s/ch but also for realizing a WDM transmission with a 1 Tbit/s channel capacity over a long distance. In this talk, we report a 1.28 Tbit/s/ch x 10 ch OTDM-WDM transmission over 1500 km. BERs below the 20% overhead FEC threshold (2x10^{-2}) were successfully obtained for all OTDM and WDM channels.
