介绍了多通道光功率自动监测系统的组成。该系统最多可以实现16路光功率实时监测,有效地解决了多芯光缆以及多路分支器件在机械和环境试验时的光功率自动监测问题。同时系统中增加的光开关和温度传感器,使系统实现了双波长实时切换以及温度实时显示的功能。系统的稳定度在短时间(15min)优于0.01dB,长时间(>8h)优于0.02dB。
The composition of multi-channel optical power automatic monitoring system is introduced. The system can achieve up to 16 optical power real-time monitoring, effectively solve the multi-core optical cable and multi-branch devices in mechanical and environmental testing of optical power automatic monitoring problems. At the same time, the optical switch and temperature sensor added in the system enable the system to realize the functions of real-time dual-wavelength switching and temperature display. The stability of the system is better than 0.01dB in short time (15min) and better than 0.02dB in long time (> 8h).
