注意光模块类型时必须要max rate和encoding两项条件同时满足
1.4 确认光线路是否存在问题
通过查询ONT和PON口的收发光功率值，结合现网实际的光路组网计算出理论衰减值，对比实际值，如果差异大于3db，可能光路存在问题，需排查光路。 1.4.1 查询ONT光功率情况

TX power current Warning Threshold(dBm) : [-,-] TX power current Alarm Threshold(dBm) : [-,-] Laser Bias Current(mA) : 21

注意前面5项参数，是OLT到终端上查询出来的值，需要对应的终端 支持
上报光模块信息且必须保证ONT正常上线。如果查询时没有显示，则跟终端类型及版本相关。
