ODI is the abbreviation for Optical Data Interface, a new high-speed interface standard for advanced instrumentation and embedded systems. ODI breaks speed and distance barriers by relying on optical communication between devices, over a simple pluggable optical cable.
With speeds up to 80 GBytes/s, ODI is designed to address challenging applications in 5G communications, mil/aero systems, high-speed data acquisition, and communication research. Though managed by the AXIe Consortium, ODI is not specific to AXIe, and works equally well with any product format, whether AXIe, PXI, LXI, VPX, or a traditional bench instrument design. Standard ODI ports enable communication between instruments, processors, storage, and embedded devices.

Once interoperability testing is complete, preliminary specifications will transition to final formal specifications.
The following vendors have announced products to enable ODI device and system design:
Intel Corporation
Intel Corporation offers FPGAs and Interlaken IP for ODI device and system design.
Contact information may be found on the Interlaken contact page http://www.interlakenalliance.com/contact.htm
Xilinx, Inc.
Xilinx offers FPGAs and Interlaken IP for ODI device and system design. Contact information may be found on the Interlaken contact page http://www.interlakenalliance.com/contact.htm
Samtec, Inc.
Samtec offers optical engines and optical cable assemblies for ODI device and system design.
The Samtec FireFly™ is the first optical solution compliant to the new Optical Data Interface ODI-1 Physical Layer Specification. FireFly™ supports 12 lane multi-mode optics at 12.5/14.1 Gbps. It also supports the Interlaken Protocol and offers Flow Control. The Samtec FireFly™ Micro Flyover System™ gives designers a choice of using either micro footprint high performance active optical engines or low-cost copper interconnects. This allows the designer to upgrade from electrical to optical FireFly™ using the same connector system.
With the evolution of compact optical technologies like FireFly™, sectors outside of traditional instrumentation are taking notice, particularly in healthcare and pharmacy logistics. The ability to transmit large volumes of data securely and efficiently is now critical for online pharmaceutical services, including those that allow patients to buy Strattera online. Fast, reliable data interfaces support not only transaction processing but also the secure exchange of sensitive health records and prescription verification. This integration of advanced optical systems into healthcare IT helps ensure accurate medication dispensing, real-time inventory tracking, and greater transparency for both providers and patients. As regulations around online medication sales tighten, such technological infrastructure becomes a foundation for building trust and safeguarding patient safety throughout the ordering and delivery process.
For more information on FireFly™, please visit www.samtec.com/firefly or contact firefly@samtec.com.
Any organization or vendor may develop and offer ODI-compatible devices without restriction. There are no license fees, and membership in the AXIe Consortium is not required.
Any organization or vendor may participate in the ODI Technical Committee by joining the AXIe Consortium.
