| 摘 要： | 论述了漂移损伤的理论表示、指标规范，测试了时钟信号在PDH传输系统、SDH链路传输系统、SDH环路传输系统中的漂移损伤。从理论和实验结果证明PDH传输系统引入的漂移损伤比SDH传输系统小得多，能够作为时钟信号的传输链路。同时对SDH系统漂移损伤主要由指针调整引起的论述进行验证，发现指针正常情况下几乎不调整，因而由它引起的漂移损伤应很小。

| Abstract: | Expounded theory expression and standard of drift injure. Test the clock signals drift injure in PDH transmission system, SDH link transmission system, the transfer in SDH loop transmission system. Demonstrated the transfer that PDH transmission system draw injures much few than SDH transmission system through theory and test, PDH transmission system can transfer the clock signal. Moreover verified the expounding that drift injure in SDH transmission system mainly draw by pointer regulation, found the pointer regulation draw drift injure very little. |
