【摘要】 提出了一种基于标记栈技术的两跳相干探测光谱幅度码(SAC)标记交换系统。利用仿真软件,搭建了包含两个转发节点、两个156Mb/s光谱幅度码标记、与40Gb/s差分正交相移键控(DQPSK)净荷的光标记交换系统。利用接收光功率与光信噪比(OSNR)分析系统传输性能,并得到结论:经两个节点传输后,标记与净荷产生的功率代价与OSNR代价均未超过3dB。更多还原

【Abstract】 Based on label stacking principles,presented is a two-hop,coherent detection spectral amplitude code(SAC)labeled system. An optical switching network with two forwarding nodes,two 156 Mb/s SAC labels,and 40Gb/s differential quadrature phase shift keying(DQPSK)payload was demonstrated by computer simulation.The system transmission performance is accessed by both received optical power and optical signal-to-noise ratio(OSNR),and the conclusions are given as:after two-hop forwarding,the power penalties and OSNR penalties are less than 3dB for both label and payload.更多还原
