本文讨论工作频率小于１０ＧＨｚ的ＳＤＨ微波传输系统的传播路径设计问题。从理论上探讨了ＳＥＳ与ＢＥＲ的关系，详细介绍了ＳＤＨ微波传输系统的性能参数及其指标，通过一个例子介绍加拿大北方电讯对ＳＤＨ微波传输系统瞬断率的估算方法。
This article discusses the design of propagation paths for SDH microwave transmission systems with operating frequencies less than 10 GHz. The relationship between SES and BER is discussed in theory. The performance parameters of SDH microwave transmission system and its indexes are introduced in detail. An example is given to introduce the method of estimating the instantaneous rate of SDH microwave transmission system by Northern Telecom of Canada.
