ONT-506 Optical Network Tester (Discontinued)

Design, Conformance, and Verification Testing of Next Generation Transport Technologies in One Powerful Solution.

Portable solution that offers multi-channel test and multi-port configuration capabilities for manufacturers, development and system verification for transport testing up to 40/43G.

40 Gbps is the next natural data rate to become commercially deployed. Along with it the 43 Gbps OTN technology with its long-reach advantages becomes of interest for manufacturers and carriers.

As packet-based services (VoIP, IPTV and direct Ethernet access) are tremendously growing, there is an urgent need for cost-effective Ethernet transportation. A strong trend points to a combination of advantages of packet-based with circiuit-based technologies. All major operators view 10GigE as the key enabling technology in today's market and are implementing LAN/WAN in combination with OTN.


  • First portable 40/43G (SDH/SONET/OTN) and jitter/wander test solution.
  • Combination of multiple technologies and multiple ports for fast and flexible testing.
  • Selection of plug-in instrument modules for SDH/SONET, PDH/DSn, OTN, EoS, Jitter, and Ethernet testing.
  • High accuracy jitter testing with high measurement margin allows for reproducible XFP/SFP qualification.
  • Preventing measurement gaps by analyzing 1000 channels in parallel of SDH/SONET systems.
  • Real multi-user behavior leverages the mainframe investment.


  • 40/43G Jitter/Wander - Supports verification of 40G SDH/SONET and 43G OTU-3 network elements. It includes evaluation of physical layer, including jitter and wander, and conformance testing of the transport layer.
  • High-accuracy Jitter/Wander - Allows for jitter and wander generation and high accuracy analysis of signals from 155 Mbps up to 10.7 Gbps.
  • ONT Module-E 10G LAN/WAN/OTN - Addresses the need of board and system testing of LAN and WAN systems and is mapped into OTN overclocked.
  • OTN G.709 - Provides full functionality for system verification of 2.7, 10.7, and 43 Gbps equipment.
  • OTN overclocked - Complete testing of a 10GigE client in OTN 11.05/11.1G and 10G FC Layer 1 in OTN 11.27/11.32G.
  • MultiChannel SDH/SONET - Simultaneous testing of all 1000 channels of a 2.5 Gbps signal at STM-16/OC-48 or STM-64/OC-192 interfaces.
  • NewGen EoS - Allows for evaluation of SONET/SDH signals up to 10 Gbps, including Virtual Concatenation, LCAS emulation, GFP, and Ethernet MAC traffic.
  • Ethernet - Enables generation and analysis of Ethernet traffic on electrical 10/100/1000M and optical GigE interfaces and allows for interworking with NewGen EoS.

Key Features

  • High coverage with 6-slot, multi-port mainframe.
  • Independent use of modules speeds up testing.
  • Easy integration into automated environments with Tcl/Tk and LabWindows libraries, multi-user access, and Linux operating systems.
  • Portable with large, color, touch screen and easy-to-use GUI.
