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.
In this article, Larry Desjardin explains the new ODI standard.
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 firstname.lastname@example.org.
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:
The Samtec FireFly™ Micro Flyover System™ is the first inside-the-box interconnect system that 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.
