Multi-band (MB) optical transmission promises to extend the lifetime of existing optical fibre
infrastructures, which usually transmit within the C-band only, with C+ L-band being also …

This paper studies the routing, modulation format, and spectrum allocation problem in elastic
fiber-optical networks for static traffic. Elastic networks, based on Nyquist wavelength …

This paper serves to highlight the gains in SNR margin and/or data capacity that can be
achieved through a proper optimization of the transceiver parameters, for example, launch …

We investigate the optimization of routing, modulation format adaptation, spectral and
launch power assignment as a means of improving the utilization of limited network …

Fiber nonlinearities define the ultimate performance bound for optical communication
systems. Todays 100 Gb/s commercial products employ advanced digital signal processing …

In this paper, we study the joint resource allocation in flexible-grid networks based on a
nonlinear physical layer impairment model. An optimization problem is formulated to assign …

In this paper, we study the impairment-aware manycast routing, modulation level, and
spectrum assignment problem in elastic optical networks. We formulate a mixed-integer …

Resource allocation for transport optical networks has traditionally used a transmission
reach constraint to estimate physical impairments. For flexible-grid networks, nonlinear …

The potential of optimum selection of modulation and forward error correction (FEC)
overhead (OH) in future wavelength-routed nonlinear optical mesh networks is studied from …

We investigate the problem of energy-efficient resource allocation constrained to quality of
service and physical requirements in orthogonal frequency division multiplexing (OFDM) …
