Figures in ONU

The picture is taken from the interface of an ONU.

What figures can be considered as good optical signal strength and bad optical signal strength?

Set the optical module of the ONU to the continuous mode, and measure the transmit optical power by using the optical power meter. It is found that the actual transmit optical power is beyond the normal range (0.5 dBm to +5 dBm).
Measure the receive optical power of the ONU by using the optical power meter. It is found that the actual receive optical power is within the normal range (-27 dBm to -8 dBm).

I cannot understand you answer.

I have tried to look for detail explanations from SOURCE, but there was an error.

I don't understand it either, it's simply something I found while googling the subject in the hopes that it would help you.

It does give you normal ranges for tx and rx or transmit and receive power.
transmit optical power the normal range (0.5 dBm to +5 dBm)
receive optical power the normal range (-27 dBm to -8 dBm)
