The recently reported high spectral efficiency (SE) and high-baud-rate signal transmission
are all based on digital coherent optical communications and digital signal processing …

Optical transmission systems with terabit per second (Tbit s− 1) single-channel line rates no
longer seem to be too far-fetched. New services such as cloud computing, three …

We propose a novel “orthogonal” TDM transmission scheme using an optical Nyquist pulse
that enables us to achieve an ultrahigh data rate and spectral efficiency simultaneously …

We demonstrate single-laser 32.5 Tbit/s 16QAM Nyquist wavelength division multiplexing
transmission over a total length of 227 km of SMF-28 without optical dispersion …

Ultra-short-and short-reach optical interconnects are the new high growth applications for
optical communications. High capacity density, high spectral efficiency, low cost, low power …

Most of the digital data transmitted are carried by optical fibres, forming the great part of the
national and international communication infrastructure. The information-carrying capacity of …

We present latest results for OTDM transmission systems in combination with digital
coherent detection achieving record-high serial data rates in a single-wavelength channel …

As traffic demands continue to grow, supporting data rates beyond 100 Gb/s will be required
to increase optical channel capacity and support higher-rate client interfaces. Advanced …

With high-bandwidth and on-demand applications continuing to emerge, next-generation
core optical networks will likely require significant improvements in reconfigurability and …

We demonstrate an optical Nyquist pulse TDM (Nyquist OTDM) transmission at 160 Gbaud
with a substantial increase in the dispersion tolerance compared with a conventional OTDM …
