Multi-ONU Emulator

Revolutionary Testing Solution for NG-PON OLTs

The Multi-ONU Emulator introduces a new revolutionary approach for testing an OLT. It emulates up to 256 ONUs, enhances the testing coverage of OLTs with additional functionalities, and ensures repeatability in test scenarios, while significantly reducing the number of ONUs needed for the test setup.  By doing so it simplifies the test setups and provides savings in space, cost and power consumption, while at the same time enhancing the test coverage.

While real ONUs may still be used for some test scenarios, the Multi-ONU Emulator can significantly reduce their number, thus saving significant space and reducing power consumption, while ensuring high reliability and repeatability in the tests.


Multi-ONU Emulator – Main Applications

  • Enables comprehensive testing of an OLT by emulation of multiple ONUs
  • Addresses testing needs throughout the OLT life cycle, including initial development, software version upgrades and troubleshooting of service-affecting issues
  • Complements the traditional end-to-end testing with multiple ONUs by providing testing coverage of additional OLT functionalities, including:
    • Different activation scenarios of multiple ONUs (such as multiple ONUs activating simultaneously, collisions between ONUs during activation et)
    • Handling of ONU “defects”, upstream errors and OMCI alarm conditions
    • Handling of rogue ONUs
    • Interoperability problems
    • Security tests – encryption and decryption
    • DBA tests
  • Significantly reduces the number of ONUs needed for the test setup
