基于NRZ+Manchester信号和偏振复用的无源光互连数据中心

无源光互连数据中心由于其低成本、低功耗和高速率受到了广泛关注.在无源光互连数据中心中,同时可用的信道数目不能超过可用波长数,波长数量也限制了总吞吐量.为了减少光互连数据中心的波长需求、提高光互连数据中心的波长利用率与可扩展性,将NRZ+ Manchester信号结合偏振复用应用于光互连数据中心,实现机架内4个服务器共享一条波长,从而将吞吐量提升4倍.通过仿真验证了该方案在10 Gbit/s速率下能够只使用16个波长实现机架内64个服务器的光互连,在25 Gbit/s速率下只使用8个波长就能够实现32个服务

地表反照率对天空偏振模式的影响

研究了地表反照率对天空偏振模式的影响.针对目前缺乏实际环境下不同时间、不同地点单一影响因素的定量测试研究,先运用libRadtran二次开发软件,仿真分析不同地表反照率下的天空偏振模式,然后利用图像式测试系统,分别在草地和沥青地表、海洋和沥青地表进行同步异地测试,定量分析地表反照率对偏振方位角和偏振度的影响.结果表明:地表反照率对偏振方位角分布基本没有影响,分布始终稳定;而地表反照率对偏振度数值有较大的衰减作用,在同一天内同一时刻下,地表反照率越大,最大偏振度值越小;地表反照率相差越大,最大偏振度值的平

基于全变分辅助的相敏光时域反射技术

采用了一种基于全变分(TV)算法的信号处理方法,用于相敏光学时域反射(φ-OTDR)系统中消除时域噪声和提高信噪比(SNR).通过将瑞利散射曲线转换成二维灰度图像,获取了瑞利散射曲线的强度和位置信息.TV算法通过梯度下降方法可以有效地平滑时域噪声并提取有用信息.实验结果表明,在长度为3.5 km的传感光纤上,采用TV算法可以有效地实现300 Hz振动信号的分布式测量,振动位置的SNR可以达到10.13 dB.在此基础上,进一步验证了TV算法对宽带振动信号的检测能力,成功实现了频率范围为300 Hz～1 k
