Procedure
Step 1 Configuring the measure parameters of the optical power meter.
l Unit of optical power: dBm
l Wavelength: 1310 nm
Step 2 Remove the fiber from the OLT PON port and connect it to the optical power meter, as shown
in Figure 1-46.

Step 3 Wait for 10s and read the value. Check the value on the optical power meter for one minute.
Step 4 After measuring the transmit optical power, insert the optical fiber removed in step 2 to restore
the connection between the ONU and the OLT.

Result
l If no value can be read or the value is lower than -40 dBm on the optical power meter, there
is no rogue ONU or continuous mode ONU connected to the PON port.
l If a value can always be read and is higher than -28 dBm on the optical power meter, there
are ONUs in continuous mode connected to the PON port.
l If a value can be read at one time and cannot be read at another time and the value is higher
than -28 dBm, there are rogue ONUs connected to the PON port (that is, an ONU that
transmits data in the timeslot that is not allocated by the OLT to it).
1.3.15.3 Measuring the Transmit Optical Power of an ONU PON Port
Measuring the transmit optical power of a PON port on the ONU helps you check whether the
optical module of the PON port functions properly and whether the ONU is a continuous-mode
ONU or a rogue ONU.
Prerequisites
l The ONU is powered on.
l The PON port is enabled.
