摘要

本文导出了光纤线路上由多个插入器件产生的累计回波损耗的计算公式。文中还介绍了用光连续波反射计法（ＯＣＷＲ）对线路上串接的１～１０只ＦＭＳ—１光纤固定连接器的累计回波损耗进行的测量，实验结果与理论值相符。计算公式表明，随着线路上插入器件的数量增多，累计回波损耗的增量愈来愈弱；而实验结果说明，当接头数量大于３以后，累计回波损耗的曲线趋于平坦，与理论计算完全一致。

Abstract

The paper deduces the quantitative calculating formula of the cumulative return loss which is caused by a few insertion pieces in a optical fiber line

and presents the experiment in which the cumulative return loss for from one to ten mechanical splices are measured by the method of OCWR. The experiment results tally with the theoretic values. Furtheymore

the theoretic calculating formula show that the addition of insertion pieces are increased

in this experiment

the curve of the cumulative return loss tends to smooth when the numbers of the splices are >3

which conclusion is in accordance with the results of the theoretic calulation.
