Modes for Optical Power Measurements
PON Burst:
use this OLT to ONT pass-through test mode to measures PON optical levels on
active, in-service PON networks.
PON CW:
use this OLT to ONT pass-through test mode to measures PON optical levels on
out-of-service PON networks that have ONU/ONT devices that can be set to maintenance CW
test mode.
PM (PM1 or PM2):
use this OPM test mode to measure any incoming optical signal level (CW,
270, 1000, or 2000 Hz) between the wavelength range of 800-1700 nm. Select a calibrated
wavelength that matches the incoming source wavelength.

PON Power Measurements
For best results, wait 15 minutes after the FX80 is powered ON.
This is
especially advisable in environments with extreme temperature changes
.
6.2.1
Setting ZERO Level
The ZERO level MUST be set before first using the FX80 for PON power
measurements. It is strongly advised to set the ZERO level BEFORE every
new batch of measurements and AFTER measurement conditions have
changed.
To set the ZERO level:
1. Press the
|MODE|
button to enter the necessary PON measurement mode (PON Burst or
PON CW).
2. Press
|F2| (ZERO)
. The ZERO notification shows briefly on the display.
