We report on the impact of wavelength division multiplexed (WDM) channel count onto the nonlinear distortions induced by an ultra-wideband (UWB) semiconductor optical amplifier (SOA).

We present an upgraded circulating loop to simply account for the actual impact of the different channels optical routings when assessing the transmission performance in the WDM transparent network

In the framework of the GALILEO signal definition, this paper endeavours to address two signal optimisation issues through results of simulations.

In this paper, we investigate the impact of timing mismatch among different sub-bands on the performance of a multicarrier spectral-slicing OFDM system with a single coherent receiver, both in the

The benefit of optical performance monitoring in terms of addressing the extent of optical transparency is analyzed with respect to network topology and traffic patterns.

We present an analysis of the energy savings when taking into account a realistic traffic model.

In a CDMA cellular system, the process of the mobile station seraching for a cell and achieving code and time synchronization to its downlink scrambling code is referred to as cell search.

We investigate the impact of the transmitter bandwidth on the nonlinear tolerance in a 112Gbit/s PDM-QPSK system with coherent detection over a 1200km dispersion managed link using standard single

We compare fixed-grid network architectures with variable-spacing OFDM based solutions.

Sleep-mode enabled transponders and regenerators yield to substantial energy savings; however, their non-negligible wake-up time may degrade the network performance.
