Distribution Analysis (optional)

Use the optional Distribution Analysis to help perform a cabinet audit and realign the splitter to ensure proper connection. Both the ONT and OLT ports on the FX120 are used.

Process

The patchcord connected between the FX120 OLT port and the splitter should remain after scanning splitter ports. Use another patchcord to connect the FX120 ONT port and the ODF (Distribution frame) port(s). The test set listens to see if there is a signal (capturing the SSN/PID), no signal, or empty port.

 

 

 

To use the advanced Distribution Analysis feature:

  1. Keep the connection from the FX120 To OLT port to the Splitter (any free port) and connect another patchcord from the FX120 To ONT port to the customer port on the ODF by swapping out the customer patchcord.

  2. On the FX120, press Toolsto access the Advanced menu, and then press Distribution analysis.

  3. After entering a location, select the Panel Type profile being audited.
    If the Panel Type being audited is not listed, speak to your regional sales team about importing a custom profile before beginning the auditing process.

  4. On the FX120, press Start.

  5. On the ODF, beginning at position A01, swap out the customer ONT patchcord with your FX120 ONT patchcord. The FX120 will listen for a re-establishment of connection from the OLT to the ONT. While the connection is under test three dots are displayed.

    Do not disconnect the FX120 OLT patchcord at any time so each port signal can be continuously scanned during the audit process. Disconnecting the customer ONT patchcord will briefly disrupt the customer connection.

  6. Wait until a letter is displayed, then disconnect the FX120 ONT patchcord from the customer port, reconnect the customer patchcord, and move the patchcord to the next customer port on the ODF. If the port is empty, mark it ”Empty” until the next occupied port is reached. If the port has a patchcord but no letter, mark the port as "No SN" or "Skip".The FX120 will listen to and collect information associated with that port. It may take up to ten seconds for the OLT/ONT to restart the connection and the FX120 to detect the information exchanged between them.
    Check all positions to avoid incorrect information being captured.

  7. After the scan is complete, press the Save button to generate a CSV file containing the information collected from the port scanning process, including Rack, Position (Port), Cable Color, SSN (if captured), Level, and/or PON ID (if captured). This file can be used to compare to the PON network database. See Working with Saved Results, Profiles, Images for details on exporting the CSV file.

    At any point during the test, a restore point can be set by pressing the orange Save button. The analysis can then be resumed from the point at which it was saved. In the event of low battery or reboot, the unit will automatically create a restore point in which the analysis may be resumed as long as the location and panel type match.

Analysis Actions

 
Description Action
To re-test the previous port

Press Previous to go back one port at a time. If multiple ports are skipped back, the scan process restarts from that point.

Stepping back more than one port at a time is not recommended because the sequential scan process restarts from the port that was skipped back to. For example, skipping back from E08 to E02 results in E03 – E08 needing to be rechecked sequentially to avoid incorrect information captured.
To jump to the next splitter bank (in splitter analysis)

Press Next Split. The unit will mark all skipped positions in the current splitter bank L (empty) automatically and move to the next splitter bank.

 

To jump to the next port (in distribution analysis)

Press Skip. The unit will move to the next port automatically.
If no SSN is detected

Press No S/N.

If there is no patch cord connected

Press Empty.
To stop analysis

Press Stop. All ports not analyzed will be marked Empty automatically.

To manually create a restore point

Press the orange "Save" button. The analysis can then be resumed from the point at which it was saved. In the event of low battery or reboot, the unit will automatically create a restore point in which the analysis may be resumed, as long as the location and panel type match.

To save results to a CSV file

Press Stop to end the test, then OK at the prompt. This file can be used to compare to the PON network database.

 

Position Indicators

 
Port Position Indicator Meaning Action
... The FX120 is waiting to detect a change in the received signal for that position. Disconnect and reconnect the patchcord from the port position on the ODP panel after 1-2 seconds. It may take up to ten seconds for the OLT/ONT to restart the connection and the FX120 to detect the information exchanged between them.
O The SSN Serial Number and/or PON-ID has been captured. No action needed. The unit will move to the next port automatically.
N No SSN Serial Number was detected. After a few seconds, press No S/N. The unit will then move to the next port automatically.
L Empty port. This could be the default or manually set. When scanning ports for the first time, all positions are L by default because the unit assumes they are all empty. Press Empty. The unit will then move to the next port automatically.
X Skipped port If needed, skip a port and recheck later, so no misinformation is collected.
