We review margins used in optical networks and review a formerly proposed margin
taxonomy. For each category of margins, we review techniques that the network designer …

We consider the transmission of Nyquist-wavelength-division-multiplexed channels based
on polarization-multiplexed m-ary QAM multilevel modulation formats with DSP-based …

In this invited contribution, we discuss technology options for bandwidth-variable
transceivers which are key components for the realization of flexible software-defined optical …

In this paper, we analyze hybrid modulation formats as an effective technology for the
implementation of flexible transponders that are capable of trading off the delivered data rate …

Four-dimensional (4-D) set-partitioning quadrature amplitude modulation (4-D SP-QAM) has
emerged as an interesting option for cost-and resource-efficient realization of bandwidth …

We investigate 128-level set-partitioning quadrature amplitude modulation (128-SP-QAM)
experimentally and compare the performance to polarization-multiplexed 16QAM both at the …

This chapter overviews the relatively large body of work (experimental and theoretical) on
modulation formats for optical coherent links. It first gives basic definitions and performance …
