1. Introduction
The FX80 power meter is designed to test passive optical networks (PON). It is used to
simultaneously measure all optical signal levels between the Optical Line Terminal (OLT) and
the Optical Network Unit/Terminal (ONU/ONT) on Gigabit B/E/GPON type networks. It can be
connected onto the PON network at any available access point along the Optical Distribution
Network (ODN). The access point can be at the OLT (central office - CO, head end or sub-
headend or remote hut), Fiber Distribution Point (FDP 1 or 2/splitter (if connectorized) or at
the ONU/ONT (customer premises - CP).ÊFigure A typical passive optical network (PON) with
possible points of measurement shows a typical passive optical network (PON) with the three
possible locations for measurement].
The unit passively monitors 1310, 1490 and the optional 1550 nm RF video downstream and
upstream PON optical power levels for compliance to standards. The measurement results
can be transfered to a PC or uploaded to the cloud using a Fiberizer Cloud account.
The operator is assumed to have received basic training in fiber optics and related testing
and measurement practices.

4.2.3. Performing Optical Power Measurements in PON
Clean the fiber before connecting it to the device.
Figure 8. A typical passive optical network (PON) with possible points of measurement
To measure optical power in the passive optical network (PON):
1. Select the necessary mode (PON Burst for active networks, or PON CW for networks
without signals) by pressing the |MODE| button. See Modes for Optical Power
Measurements for details.
2. To test a PON network, you can insert the FX80 at one of above locations (see Figure A
typical passive optical network (PON) with possible points of measurement) along the
PON network: OLT, Fiber Distribution Hub/Point (FDP) or ONU/ONT. You will need at
least one extra patchcord to perform a test. If PON network elements have SC/UPC
connectors and FX80 has SC/APC, you will need two hybrid patchcords.
When testing at the FDP-A location, if there is no drop line installed, you will see 1310 nm
upsteam only if you temporarily connect a fiber to the ONT which may require two patch
cords.
3. Connect the fiber with 1490/1550 nm downstream traffic to the left-side OLT test port.
Confirm that the 1490 nm signal is immediately detected. 1550 nm will only appear if the
PON network includes RF video signal traffic (RFoG). If no signal is detected, begin
troubleshooting and make sure you are connected to the proper test port.
FX80 PON User Manual D07-00-115P RevA01
Page 17 of 36

4. Once a good 1490 nm signal level is detected, connect the patchcord between the FX80
ONU/ONT right-side test port and the PON network element closest to the ONU/ONT to
measure the 1310 nm upstream signal. There may be a delay in seeing 1310nm signal. If
the ONT/ONU is power-cycled, it can take one minute or longer before the network is
fully operational.) The measurement results are then shown on the screen (the example
below shows typical values one might expect when connected at ONU (location C) and
no P/F thresholds have been set):
Figure 9. PON Burst mode measurement results as values
If P/F thresholds have been set, the measurement results are presented as Pass or Fail (see
an example below):
