A very promising energy-efficient strategy in core networks is to put unused transponders into a low-power idle state.

Submarine systems based on nonzero dispersion shifted fibres are numerically investigated at 40 Gbit/s channel bit rate over 10 500 kill in the whole C-band.

Monitor placement in transparent networks is optimized as a function of traffic loading, and wavelength route correlation is shown to collapse the monitoring requirement for transparent domains gre

We study the impact of channel correlations on the accumulation of nonlinear interference noise in WDM transmission experiments.

We investigate the impact of WDM channel dynamics on the performance of 42.7-Gb/s DBPSK and DQPSK signals in a transparent optical link, and show their robustness against rapid and large power chan

Polarization dependence in microbend gratings is an inherent problem.

UTRAN is a 3G radio access network based on the wide-band DS_CDMA technology. An important feature of UTRAN is its multimedia service capability.

Content broadcasting over wireless networks heavily relies on Application-Level FEC codes to improve transmission robustness in front of channel impairments.

Impairment Mechanisms for SSB Mobile Communications at UHF with Pilot-Based Doppler/Fading Correction By K. W. LELAND and N. R.

We study strategies of relaxing physical layer constraints in flexible transparent optical transport networks through traffic engineering as well as through impairment-aware traffic management supp
