摘要
在架空光缆条件下,日昼温差的变化会严重影响到时钟的漂移特性。本文首先对SDH光传输系统的漂移影响因素进行理论分析,然后给出架空光缆条件下的漂移测试结果,并对测试数据进行了分析,最后对架空光缆的温度漂移特性进行了讨论并给出了规划建议。
In aerial optical cable conditions, the diurnal temperature variation can seriously affect the drift performance. In this paper, first drift effects on SDH optical transmission system were analyzed, and then the test results were given under the condition of aerial optical cable, finally the temperature drifting characteristics of aerial optical cable and plan- ning proposal were discussed.
