Imagine if it was possible to build multi-channel microwave radio systems leveraging optical rather than copper interconnects. Several benefits of this paradigm shift seem likely to follow including:
- Streaming sample, control & configuration data, as well as reference clock and synchronization signals via fiber simplifies radio front-end design, signal distribution whilst simultaneously reducing cable mass
- Eliminating copper signal wiring in future radio designs offers increased architectural freedom and flexibility whilst reducing crosstalk and inter-channel interference for better performance.
- The optical concept substantiates a valuable separation of front-end analog design from back-end digital signal processing heralding the arrival of fully digital antennas with enhanced operation arising from advanced electronic beam steering.
