报导了掺铒光纤放大器（ＥＤＦＡ）在测试技术中的应用情况。按照文中介绍的方案，把ＥＤＦＡ配置成光源来用，它在１５３０～１５７０ｎｍ 间输出光功率大于１０ｍＷ；稳定度为±０．０２ｄＢ。用这一光源测试了几种光纤器件的主要性能指标，与用调谐激光源测试相比较，两种光源测试的结果是一致的，这表明这种ＥＤＦＡ－ＡＳＥ非相干波长可调光源在测试技术中使用是完全可行的。
Reported the application of EDFA in testing technology. In accordance with the program described in the article, the EDFA configured as a light source to use it in the 1530 ~ 1570nm output optical power greater than 10mW; stability of ± 0.02dB. Using this light source to test the main performance indexes of several optical fiber devices, the results of the two light source tests are consistent with those of the tuned laser source test, which shows that the EDFA-ASE incoherent wavelength tunable light source has the advantages in testing technology In the use of is entirely feasible.
