52417 最后运用实际网络数据验证了该方法的可行性和有效性。 The feasibility and effectiveness of this method are verified by the practical network data.
52418 针对目前电缆故障引起的频繁停电维修影响了人们正常生活的问题，提出了一种基于偏振光时域反射仪分布式光纤传感技术的电缆安全状态监测系统， Current power outage caused by cable failure seriously affects people's normal life. Therefore, an effective monitoring system is required to monitor the status of the cable online.
52419 该系统通过计算差值图的峰度系数来衡量曲线变化的陡峭程度，从而进行入侵点的判断。 In this paper, we propose a cable safety monitoring system based on polarization optical time-domain reflectometer. The system judges the intrusion point by calculating the kurtosis coefficient for the different maps.
52420 实验表明，系统工作于1μs的脉冲宽度时对扰动位置的判断误差低于100m。 When the system is operating at a pulse width of 1μs, the error on the intrusion localization is less than 100 m.
52421 通过设置合适的振铃宽度，可以将误报率降至0. 5%以下。 By setting the ring width appropriately, the false alarm rate can be reduced to be less than 0. 5%.
52422 在不同的电缆长度和电缆布置环境情况下，能够通过对系统参数的配置来满足使用需求。 In the case of different cable lengths and cable layout environments, the requirements for different users can be satisfied by setting the parameters under different system configurations.
52423 针对双平行马赫-曾德尔调制器工作点漂移的问题，提出一种适用于16进制正交幅度调制的双平行马赫-曾德尔调制器自动偏压控制算法。 This paper proposes an automatic bias control algorithm for dual parallel Mach-Zehnder modulator which is proposed for 16 Quadrature Amplitude Modulation (16QAM) formats to solve the working points drifting problem in dual parallel MachZehnder modulators.
52424 算法分为两个部分，初始化部分和跟踪锁定部分。 The algorithm is divided into two parts, which are initialization part and tracking locking part.
52425 初始化部分的目的是找到一个接近偏置电压的工作点，以减少跟踪锁定部分算法锁定工作点需要花费的时间; The purpose of the initialization part is to find a working point close to the bias voltage to reduce the time required to lock the working point in the tracking locking algorithm.
52426 跟踪锁定部分使用抖动信号检测法找到精确工作偏置点，并且能实时地跟踪随环境变化的偏置点， The tracking and locking parts use the detection method of dithering signal to find accurate working bias point, and track the offset point varying in real time.
