One promising and competitive solution to keep up with the rapid growth in data traffic while
at the same time addressing increasing network cost, is the efficient reuse of legacy optical …

Abstract 100Gb/s end‐to‐end broadband optical solutions are attractive to cope with the
increasing demand for capacity. Polarization‐division‐multiplexed (PDM) quaternary‐phase …

There has been much interest in the non-linear frequency-division multiplexing (NFDM)
transmission scheme in the optical fiber communication system. Up to date, most of the …

Coherent detection offers high spectral efficiency and receiver sensitivity, but digital signal
processing (DSP)-based coherent receivers may be prohibitively power hungry for data …

We investigate the transmission performance of 224Gbit/s polarization-division-multiplexed
16-state quadrature amplitude modulation (PDM-16QAM) for systems employing standard …

In this paper, we firstly review the progress in ultra-dense wavelength division multiplexing
passive optical network (UDWDM-PON), by making use of the key attributes of this …

We experimentally demonstrate 101.7-Tb/s transmission over 355 km spans of standard
single-mode fiber (SSMF) at a net spectral efficiency of 11 b/s/Hz. A total of 370 dense …

The introduction of coherent digital optical transmission enables a new generation of high
speed optical data transport and fiber impairment mitigation. An initial implementation of …

Coherent detection with receiver-based DSP has recently enabled the mitigation of fiber
