In October of this year, the AXIe Consortium, the VITA trade association, and six companies announced a new instrumentation standard called the Optical Data Interface, or ODI for short. The companies endorsing the standard were Conduant, Guzik, Intel, Keysight, Samtec, and Xilinx.
ODI shatters conventional distance and speed records. Based on optical links between instruments, ODI can stream data up to 20 GBytes/s from a single optical port, with speeds up to 80 GBytes/s through port aggegation. It is a high-speed point-to-point interface that carries real-time signal data. The speeds, data formats, and timestamps are optimized for wide bandwidth multi-channel data, as found in 5G, radar, electronic warfare, and other RF applications. In October, I wrote gave a brief technical overview of the ODI standard, which you can read here. In this column I will dive deeper, and show some of the unique aspects of ODI that don’t exist in other instrument buses.
