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156 Mb/s光谱幅度码标记、与40 Gb/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3 dB.

Transmission Characteristics of Multi-hop Coherent Detection Spectral Amplitude Code Labels Switching System |
| |
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 156Mb/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. |

Keywords: | spectral amplitude code (SAC) coherent detection multi-hop transmission optical label switching |
