GPON Optical Levels

We are deploying our first GPON network, and are trying to get a sense of what is a good optical level per ONT. The equipment install guide says the following: Measure the levels of the 1550 dBm and 1490 dBm receive optical inputs using an optical power meter. The input range should be between -27.0 dBm to -8 dBm. Attached are the measurements I can see and graph from the ONT side. Trying to get a sense of what range we would graph as good (green) measured within the clear, what we could consider yellow as working but out of optimal range, and what we could consider poor (red) range. What about the Laser Bias Current, Optics Module Voltage, and Optics Module temperature?
