256 Tb/s data rates over 200 km distance have been demonstrated on single mode fiber optic, which works out to 32 GB of data in flight, “stored” in the fiber, with 32 TB/s bandwidth. Neural network inference and training can have deterministic weight reference patterns, so it is

Interesting idea. You could slow down light even more and increase data stored per km by using higher refractive index materials.
Or just use vacuum, which costs nothing, over a longer distance … 🤔
