“…(5) where X refers to specific parameter of either EDFA or SOA system, PE x -power efficiency [W/Hz], BW x -utilised spectral bandwidth [Hz], P x -total power consumption [W]. (6) Unlike results of the previous studies [14], [15], [18], power consumption of ROADM terminals was not included in total power consumption calculations, focusing on system components that required defining the amount of used power and emphasising signal generation and regeneration power needs.…”

To evaluate potential utilization of semiconductor optical amplifiers (SOAs) as a wideband amplification alternative to erbium doped fibre amplifiers (EDFAs) in dense wavelength division multiplexed (DWDM) coherent systems, the authors discuss changes in power consumption levels required for a single bit transmission. The research evaluates the power efficiency parameter for WDM transmission systems using both amplification schemes – EDFAs that utilise standard C-band and SOAs assuming 75 nm amplification spectral band. The power efficiency levels have been estimated for five transmission spans with maximal distance of 640 km. The standard 50 GHz channel spacing has been chosen for both system configurations to allocate 100 Gbps dual-polarization quadrature phase shift keying (DP-QPSK) optical signals. The simulation schemes are described along with the critical parameters, derived from the recent relevant studies that should be taken into account considering usage of SOAs as in-line amplifiers.
