[10] Graphical representation of the power.
[11] Reference value from which is calculated the relative losses. Reference value
can be changed.
[12] Modulation Identification.
[13] The OLT led indicates the status of the OLT signal with respect to the
ATTEN. THRESHOLD value defined in the Configuration Menu. Three
indicator light colours are possible and each colour represents status signal
with respect to this attenuation threshold value. They are GREEN (when all
signals are below the attenuation threshold value), AMBER (when some
signal are above the attenuation threshold value) and RED (when all signals
are above the attenuation threshold value).
To navigate through the editable fields on the screen press SEL
selected field changes to shaded.
To edit the wavelenght or the threshold group, select it and press

To capture a new reference value, select the current reference value and press
both keys

To make or consult a logger refer to the section LOGGER Function.

4.2.6 xPON POWER METER Function.

This function makes optical measurement on active RFoG and xPON networks.
In the PROLITE-67 are integrated selective filters needed to measure the optical power
at wavelengths used in networks RFoG and xPON. Thanks to these selective filters the
instrument identifies automatically each wavelength, recognizing the calibration
parameters for each signal. This also prevents confusing between input ONT and OLT.
The burst detector measures the optical power of every burst sent by the ONT at 1310
nm (xPON). The Downstream channel measures selectively the average optical power
of the signal sent by the OLT at wavelengths 1490 nm and 1550 nm. When measuring,
the service is not interrupted, since it uses the "pass-through" method that is the only
proper way to measure the upward flow, as on the GPON networks it can only transmit
at the request of the OLT.
