摘要

研究发现，在光通信系统中，同轴电连接器的接触失效是造成误码率高的重要原因之一。从理论上和实验上研究了理想电路中触点失效对数字信号传输的影响。在此基础上，进一步从理论上研究了实际应用中广泛存在的非匹配电路中触点失效对数字信号传输的影响。推导表明，非匹配电路中触点失效对信号传输的影响是非常复杂的。电路中可能会出现信号的多次反射，从而大大增加误码发生的概率。

Effects of electric contact failure on signal transmission in unmatched circuits

It is found that one of the most important reasons for high error code rates in optical communication systems is the contact failure of the coaxial electrical connectors installed in the systems. The influences of the contact failure on the digital signal transmission in ideal circuits have already been studied theoretically and experimentally. Based on those results, this paper further studies theoretically the effects of contact failure on the digital signal transmission in unmatched circuits, which can happen widely in practical applications. Derivation shows that the effects of contact failure in unmatched circuits on the signal transmission are very complex. Multi-reflection of the signals may occur in the circuit, and the probability of occurrence of error codes can be increased significantly.
