Next-gen, high-performance Test and Measurement platforms support faster data rates than current solutions. Prevailing devices communicate over copper interfaces in standard form factors and traditional bench instrument applications.
At increased data rates, signal integrity concerns over copper cable assemblies and connectors limit the reach and interoperability of systems. The new Optical Data Interface (ODI) is a new high-speed interface standard for advanced instrumentation and embedded systems.
ODI enables higher data rates over longer distances. It increases interoperability in an open system by connecting a fiber-optic data link between two devices regardless of functionality.
ODI is based on a standard optical connector that can be placed anywhere on any device. It defines a highly functional and expandable physical layer. Key specifications include:
- 12-lane multimode optics
- 12.5/14.1 Gbps Data Rates
- Interlaken Protocol
- Flow Control
Samtec FireFly™ Micro Flyover System™
ODI uses Samtec’s FireFly™ Micro Flyover System™ as the physical layer. FireFly™ is the first interconnect system that gives a designer the flexibility of using micro footprint high-performance optical and low-cost copper interconnects interchangeably with the same connector system.
Samtec FireFly™ copper and optical cable systems provide the flexibility to achieve higher data rates to 28 Gbps and/or greater distances, simplifying board design and enhancing performance.
The system’s miniature footprint allows for greater density and closer proximity to the IC, enabling chip-to-chip, board-to-board, on-board and system-to-system connectivity.

Connecting ODI-Compliant Data Recorders to Xilinx Development Boards
High-speed data acquisition (DAQ) systems can be tough to develop. The analog front-end needs to be fine-tuned to a specific application. The digital back end converts and processes the data while combining many channels into a usable data stream.
FPGA development boards, like the Xilinx® Virtex® Ultrascale+ FPGA VCU118 Development Kit, are often used to emulate these applications. They typically offer flexible copper and optical interfaces that can support popular interfaces like ODI.
Longmont, CO-based Conduant recently developed a white paper that details connecting their data recorder to the VCU118. The Conduant StreamStor® supports data recording and playback at rates up to 20 GB/s (160 Gb/s). StreamStor® leverages FireFly™ to connect to a VCU118.
FireFly™ is protocol agnostic, so StreamStor® can connect to almost any Xilinx FPGA development kit using any number of protocols. The Conduant HSS-8324 board provides the optical interface to the Cobra recorder via a 24-fiber MTP/MPO connector.
