FX120 Quick Guide
When powered on the test set automatically loads the GPON application.
Step 1: Power on Test Set
Press and hold the Power button 
for two seconds, until a confirmation tone (beep) is heard, and the VeEX logo appears on the screen, then release the power button. The test set will take a few seconds to boot up, automatically start the GPON application, detect the optical light source, load the default test profile, and begin monitoring.
To turn the test set OFF, press and hold the Power button until two confirmation tones (beeps) are heard.
By default, the test set always starts in GPON mode 
, as indicated by the Test Mode Selection button. It can detect GPON, XG(S)-PON, EPON, and 10G-EPON automatically. When in Speed Test mode, it can detect 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T and even legacy 10/100BASE-T automatically.
Starting/stopping/restarting measurements from the OPM menu (see OLT and ONT/ONU Messages and Measurements) starts/stops/resets items in the GPON Summary Screen , such as the Power Level Graphs and Active ONU List in Advanced OPM Mode. To clear the PLOAM list, go to the respective PLOAM menu and press the Clear button.
Step 2: Configure Test Profile
Tap Setup and configure the test profile settings according to the PON class and xPON / XGS-PON ITU-T and IEEE Test standards.
GPON OPM Setup menu
XG(S)-PON OPM Setup menu
EPON OPM Setup menu

Step 3: Insert Patch Cord into FX120 OLT test port.
Inspect and clean the FX120 test ports. Inspect and clean the fiber patch cord from the OLT and insert it into the FX120 OLT test port.
 Warning: Never look directly into the beam of an active optical source as this may result in harmful eye damage from radiation exposure.

If 1490/1577nm light is detected, the 1490/1577nm Status will display OK. Verify that the measured 1490/1577nm signal level is Green (see Signal and Synchronization Status). Confirm TC-Sync DS displays OK DL.
If you are not able to achieve TC-Sync, contact VeEX technical support.
All DS LEDs should turn from Red to Green. If any LED remains Red, clean and inspect the OLT connectors again.
Step 4: Connect Splitter to FX120 ONU/ONT test port.
Inspect and clean the patch cord connectors and connect the FX120 ONU/ONT test port to the Splitter ONU/ONT test port.
If 1310/1270nm light is detected, the Status will display OK. Verify that the measured 1310/1270nm signal level is Green (see OPM Test Mode).

Do NOT connect the FX120 between the OLT and splitter.
|
The FX120 should be connected between the splitter and ONT.
If you are not able to achieve TC-Sync, contact VeEX technical support.
All US LEDs should turn from Red to Green. If any LED remains Red, clean and inspect the ONU connections again.
LEDs
Green: The measured signal is above the critical threshold.
Yellow: The measured signal is below marginal and above critical.
Red: The measured signal level is below the critical threshold and does not meet the specification.
Step 5: Save Results
Press the SAVE button 
and use the touch-screen keypad to enter the name (overwrite or edit), then tap Apply.
Auto-Naming: By default, the test set auto-naming feature uses the current date and time to generate a default unique name for every test result (YYYYMMDD_hhmmss). The auto name can be rewritten or specific prefix defined to be added to it (e.g., to identify site, cabinet, rack, customer or the technician running the test).
Upon saving results, a secondary form is displayed to enter additional information about the Job ID/Work Order, technician, location, and comments.
This creates more complete test reports and is required if the test set is registered to the VeSion R-Server Centralized Workflow and Results Management System.
When the Advanced Saving option in
Step 6: View Results & Generate Report
To access the test results stored in the test set:
-
Press
, then press 
on the top left of the screen. -
Select
-
Select the desired results file to open the test report.
To navigate the test results report, use the links in its Table of Contents and the right rocker switch to scroll Up and Down.
Other Test Features
Fiberscope
The Fiberscope test application can be used in conjunction with any VeEX Digital Fiber Inspection Microscope.
Flow
The Flow application performs and compiles multiple tests into a single job report.
OLTS/OPM
The Fault Locator test application can be used to identify fiber bends and breaks.
OTDR Viewer
This built-in application allows the test platform to view previously saved .sor trace results and edit events, as needed. IF an OPX-BOXe is connected to the platform via direct USB connection, WiFi or Bluetooth®., this built-in application can also be used to control all OTDR test functions.
V-TEST
The V-TEST feature qualifies network TCP/HTTP protocol performance by testing Internet speeds up to a full line rate against a server to verify the maximum download and upload data rates attainable by subscribers' high-speed or Gigabit Internet services.
