This is a good command for determining if your signal in your fiber is good or not. There are limits to everything, and fiber signal is no different. There is a command "show interface gig 1/1 trans detail" that I use to help determine this. Plug in what interface you want to monitor to check this.
Notice below, my actual reading is on the left. -24.9dBm. The range for warnings are between 0 and -23, so Im obviously out of the range of the warning level. But, Im still above the low reading of -26.0dBm.
