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.
This article describes some of the latest ODI-enabled products from Keysight and Conduant.
The following four ODI specifications are provisional, meaning that they are open for comments through December 14. After that time, they will be re-posted as final specifications. Please address all comments to Larry Desjardin, Technical Committee Chairman, at email@example.com.
VITA 49 standards may be download for a modest fee from the VITA Online Store above
Once interoperability testing is complete, preliminary specifications will transition to final formal specifications.
ODI Component Vendors
The following vendors have announced products to enable ODI device and system design:
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.
For more information on FireFly™, please visit www.samtec.com/firefly or contact firstname.lastname@example.org.
