* 产品描述

产品描述:
该PMD仿真平台(PMDE)模拟了PMD的真实性质。PMDE-301利用通用光子学的3个专利偏振控制器和3条差分群延迟(DGD)线,生成了一个精确的麦克斯韦概率密度函数,其DGD平均值可调。动态PMD仿真平台在PMD效果评估和PMD测试装置的校准中有着广泛的应用。该方法也可用于其它PMD补偿器的性能测试。PMDE提供了一个大范围可调的DGD值,具有非常高的重复性和温度稳定性。其二阶PMD值与真实光纤的匹配度为70%(当两个pmde -301级联时,匹配度为95%)。PMDE具有易于重构的主机和控制接口,可以执行先进的PMD仿真技术,包括重要性采样、多标准采样等,比目前市场上的其他系统具有更高的效率。“一体化”平台提供了PMD仿真/补偿系统所需的大部分功能,包括一阶和全阶PMD仿真、DGD生成、偏振控制和置乱、级联可行性、PMD慢动态等。


特点:

  • 多功能
  • 测量速度快
  • 全阶PMD仿真
  • 精度高、可靠性高
  • 可调统计信息
  • 可重构
  • 随机或缓慢的PMD动态


应用

  • 模拟PMD对系统的影响
  • PMD补偿器评估
  • 校正PMD测量装置
  • 重要性抽样
  • 分布式PMD补偿

Product Description:
This PMD Emulation Platform (PMDE) simulates the true nature of PMD.   Using 3 of General Photonics’ patented polarization controllers and 3 differential group delay (DGD) lines, the PMDE-301 generates an accurate Maxwellian Probability Density Function with a tunable mean DGD value.  The dynamic PMD emulation platform has broad applications in PMD effects evaluation and in calibration of PMD testing setups.  Also, it can be used in performance testing of other PMD compensators.   The PMDE provides a large, tunable range of DGD values, with very high repeatability and temperature stability.   Its 2nd -order PMD value is 70% matched with that of real fiber ( ~ 95% when two PMDE-301s are cascaded).   With its easily reconfigurable mainframe and control interface, the PMDE can perform advanced PMD emulation techniques, including importance sampling, multicanonical sampling, etc., with much higher efficiency than other systems currently on the market.   The “all-in-one” platform provides most of the desired features for PMD emulation/compensation systems, including first-order and all-order PMD emulation, DGD generation, polarization control and scrambling, cascading feasibility, slow PMD dynamics, etc.


Features:

  • Multiple functions
  • Fast measurement speed
  • All –order PMD emulation
  • High accuracy and reliability
  • Tunable Statistics
  • Reconfigurable
  • Random or slow PMD dynamics


Applications:

  • Emulating PMD effects on systems
  • PMD compensator evaluation
  • Calibrating PMD measurement devices
  • Importance sampling
  • Distributed PMD compensation
