6、以下简称稳定光源)是光通信线路铺设、设备维护、科研和生产中的重要设备。在光纤衰减的测量、线路中连接损耗的测量、各种活动连接器的插人损耗及光电器件和接收机灵敏度的测量中是不可缺少的设备。稳定光源的发光器件一般为工作波段在1310nm或1550nm的激光器(LD)或发光二极管(LED).3计量性能要求3.1光源输出功率(最大)应与说明书上给出的一致。3.2光源输出功率的时间稳定度3.2.1长时间(>-5h)稳定度应优于10.2dB.3.2.2短时间(15min)稳定度应优于士0.02dB.3.3光源的光谱特性应与

7、说明书上给出的一致。4通用技术要求被检稳定光源应处于以下状态:有规格、型号、制造厂名、设备编号，该稳定光源作为计量器具应有计量器具制造许可证(恒)标志及相应的警示标记。各调节旋钮、按键、开关等均应工作正常，无松动现象，各接插件紧密配合，接触良好。仪器完好，不应有影响使用的机械损伤。被检稳定光源应带有说明书。5计量器具控制计量器具控制包括:首次检定、后续检定和使用中检验。首次检定是对用户新购置的、或制造厂新生产的稳定光源进行的检定。首次检定结果应确定是否满足第3条计量性能要求。后续检定包括有效期内的检定、周期检

8、定以及修理后的检定。后续检定时，应具有上次的检定证书，且光源上有相应的检定标记。使用中检验是为了检查检定标记或检定证书是否有效，标记是否损坏，状态是否有明显变动，是否超差。5.1检定条件5.1.1检定环境条件5.1.1.1环境温度:(20士5)CJJG958-20005.1.1.2检定期间内温度变化:士20C5.1.1.3相对湿度:镇85%5.1.1.4电源电压:(220土11)V5.1.1.5实验
