    Fiberscope with Universal 2.5mm UPC and APC male tip, SC/APC bulkhead and SC/UPC bulkhead tips to inspect optical connectors. Patch cord – one to two patch cords depending on what is required to insert the FX120 between the splitter and ONT. Mating blue (UPC) with green (APC) connectors will result in excessive insertion loss, reflectance, and possible damage to the optical connector.

The FX120 should be connected between the splitter and ONT. 6.0.1 OLT and ONT/ONU Messages and Measurements OLT Information Table Below the OLT and splitter diagram block, a table displays the transmitting signal level (TX), PON ID, PON Type, and ODN class.

  • Page 15: Signal And Synchronization Status

    At any customer location after the OLT and splitter, the FX120 will display 1490nm and 1310nm signal level values for GPON, 1577nm and 1270nm for XGS-PON, and 1550nm for RF/CATV. ODN Loss is the difference between the transmitting signal from the OLT (TX) and the DS signal level measured at the FX120 location.

    The FX120 is designed for use at the customer premises to aid with ONT/ONU activation and troubleshooting The FX120 is connected at the customer premise 1. Power up the FX120 test set. Testing should start automatically. Starting/stopping/restarting measurements from the OPM menu (see Information Table) starts/stops/resets items in the OPM Summary screen - the power level graphs and the Active ONU list in Advanced Mode.
  • Page 17 XGS-PON OPM Setup menu 3. 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 4.
  • Page 18 In order to synchronize with the ONU, the FX120 needs to see the ONU registration process. Therefore, only connect the ONU AFTER the FX120 application is already running. Otherwise, power cycle the ONU after the FX120 application is running if the ONU is already connected to the FX120.

    7.0 Advanced Mode Advanced Mode features advanced troubleshooting tests beyond basic signal level measurements. Further investigation may be required when the OPM test mode indicates good signal level and TCSync is good but network is generating alarm or errors. Advanced Results provides a summary screen of network status and reports system errors/alarms status. PLOAM captures and decodes PLOAM messages exchanged between the Optical Line Terminal (OLT) and ONT.

  • Page 29 Appendix A xPON Definitions Activation: A set of distributed procedures executed by the OLT and the ONUs that allows an inactive ONU to join or resume operations on the PON. The activation process includes three phases: parameter learning, serial number acquisition, and ranging. Bandwidth allocation: An upstream transmission opportunity granted by the OLT for the duration of the specified time interval to the specified traffic-bearing entity within an ONU.
  • Page 30 Pre-assigned delay (PrD): The requisite delay that all the ONUs on the PON are required to use prior to completion of the ranging phase of the activation process. Quiet window: A time interval during which the OLT suppresses all the bandwidth allocations to the in-service ONUs in order to avoid collisions between their upstream transmissions and the transmission bursts from the ONUs that have just joined the PON and are undergoing the activation process.
