Abstract

Abstract 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.

半导体光放大器取代掺铒放大器对DWDM系统功率效率变化的影响

摘要为了评估半导体光放大器（SOA）作为掺铒光纤放大器（EDFA）的宽带放大替代品在密集波分复用（DWDM）相干系统中的潜在应用，作者讨论了单比特传输所需功耗水平的变化。该研究评估了使用两种放大方案的WDM传输系统的功率效率参数——使用标准C波段的EDFA和假设75 nm放大光谱波段的SOA。估计了最大距离为640公里的五个传输跨度的功率效率水平。两种系统配置都选择了标准的50 GHz信道间距，以分配100 Gbps双偏振正交相移键控（DP-QPSK）光信号。模拟方案和关键参数一起进行了描述，这些参数来自最近的相关研究，考虑到SOA作为在线放大器的使用，应将其考虑在内。
