4.2.2.4 THRESHOLD function
The THRESHOLD function allows you to edit the threshold values that will be
used during measurement.
To access the THRESHOLD function:
1.- From the GPON METER function press the soft key THRESHOLD [F4].
The THRESHOLD function allows you to define a minimum threshold value
(LOW) and maximum (HIGH) of acceptability for each wavelength (Fig. 12.-).
Once defined, they appear in the graph at the GPON METER function, in the
shape of a line with an "x" in the middle (--x--) (Fig.- 7.-).
Status level defined by the threshold values are:
-
Power level above the maximum threshold value is equal to HIGH.
-
Power level between the maximum and minimum threshold value is equal to
GOOD.
-
Power level below the minimum threshold value is equal to LOW.
In addition, LEDs associated with the ONT and OLT signals [5] change its colour
depending on the power signal level.
-
If level is LOW, the colour of the LED is RED.
-
If the level is MEDIUM, the colour of the LED is GREEN.
-
If the level is HIGH, the colour of the LED is ORANGE.
