问问有没有大佬，最近用猫棒发现老是掉线，光信号为 -20dBm，查看猫棒后台发现如下日志

-20dbm 是可用的。我的华为 P602E 光猫看电信线路光功率是-22dbm ，有时候能降到-23dbm ，完全稳定无掉线，速率正常。后台写的-27dbm 才算弱光。

@morpheuszero2023 我这里目前都是在-19 ～ -21 徘徊，不知道怎么回事有的时候会掉线

打勾忽略 polam 那个错误。貌似各地运营商最近半年，都改造什么东西了

[ghhccghk]

@fairytale 我试试看

下行帧丢失。
可能有那么“一瞬间”，光功率低于临界值

[fairytale]

电信移动都很稳，猫棒无报错。联通今年开始出现 polam 并且猫棒一个月必死机。

[simplove]

光纤接头上面可能有灰尘，或者光纤有过度弯曲导致质量下降，只看光功率没用

[ghhccghk]

叫电信来排查了，貌似是他们那边问题
