摘要
讨论了光缆数字线路系统中信号漂移的累积和表达方式;用实验验证了当光缆线路上温度变化的分布不同时,系统中数字信号漂移累积的温度补偿性;导出了在几种典型温度变化分布的情况下系统中数字信号日漂移量和年漂移量的计算公式。
The cumulation and expression of the signal wander in optical cable digital line systems are discussed. The temperature compensation properties of the signal wander in optical cable line with different distribution of the temperature variation are demonstrated. The formulas calculating day wander and year wander of the signal in optical cable digital line systems under some typical temperature distribution are concluded.
