基于传输性能指标预测的光缆可用性评估

摘要

为准确评估既设光缆未来任务时间是否适用于高性能光端传输设备，提出一种基于传输性能指标预测的光缆可用性评估方法。在构建组合模型准确预测光缆性能指标的基础上，根据光端设备对线路允许损耗变化范围的要求评估光缆的可用性。通过实例验证说明了基于性能指标预测的光缆可用性评估方法的准确性和有效性，对解决光缆可用性评估问题具有一定的参考价值和指导意义。%The method of the optical cable usability evaluation is proposed based on the performance indicators forecast in order to accurately assess whether the existing optical cable can be adapted to the high-performance optical equipment in the future. A model which can accurately predict the performance of the optical cable is first built.Then the method predicts the usability of the optical cable according to the requirements of the allowable loss range of the optical equipment based on the model.The accuracy and validity of the method is demonstrated via the experiment.The proposed method may provide reference and guid-ance to solve the problem of cable usability evaluation.
