ONT Optical Network Tester Family

Highly configurable, multi-application and multi-port platform for system verification and acceptance testing.


High-speed testing for high-speed optical networks

The modular design of the ONT-600 platform offers high flexibility and lets users operate multiple test modules simultaneously. The ONT-600 comes in a variety of mainframes and application modules, ranging from “single-port” point tools up to a full 19” rack-mounted multi-slot, multi-port and multi-user solution that satisfies sophisticated SVT needs.


All application modules share the same GUI and identical automation and scripting, so that they can be used throughout the product development cycles.


  • Detailed hardware level testing with unframed and protocol based traffic.
  • 25G, 50G, 100G and 400G Optical Modules validation: electrical lanes stressing (clock offset variation, TX pre-emphasis and RX equalization manipulation, dynamic skew) per IEEE standards, MDIO/I2C management interface verification (peek/poke, HW pins control, MDIO/I2C Dump)
  • Support for OTN, Ethernet, Fibre Channel, CPRI, and SONET/SDH
  • Qualify PTP (IEEE 1588) implementations in optical networks and equipment
  • Full service disruption and latency measurements for all supported technologies
  • Equipment Manufacturers: Support for R&D, SVT (system verification/test), and production environments covering the entire product life cycle
  • Service Providers: Conduct product qualification and benchmark testing before deployments and bring to the field for first office applications (FOA)
  • Data Centers: Fully verify data center interconnect elements and long-haul transmission elements for quality and performance and fully stress and verify pluggable optics including active optical cables.

Key Features

  • Multiple mainframe options including rackmount, desktop, and modules with built-in display for mobile test needs.
