To check the Rx and Tx power levels on a GPON OLT for an ONU or ONT, you can use the command line interface (CLI) on the OLT. The specific steps may vary depending on the OLT model and vendor, but here is a general process:

Connect to the GPON OLT using a terminal program like Putty or HyperTerminal.

Enter the “enable” mode to access privileged commands.

Use the “show interfaces gpon onu_id” command to check the Rx and Tx power levels for the specified ONU. The “onu_id” is the unique identifier assigned to each ONU connected to the OLT.

The Rx power level refers to the optical power received by the OLT from the ONU, and the Tx power level refers to the optical power transmitted by the OLT to the ONU.

The power levels are usually measured in decibels (dBm). A higher Rx power level indicates a stronger signal from the ONU, and a higher Tx power level indicates a stronger signal from the OLT.

It is important to monitor the Rx and Tx power levels to ensure that the optical link between the OLT and ONU is functioning properly and to detect potential issues such as optical power loss, fiber damage, or distance limitations.
