Visible light is part of the electromagnetic spectrum and 10,000 times bigger than the radio spectrum, affording potentially unlimited capacity.
But there are drawbacks: block the light and you block the signal …
the technology was still in its infancy and needed further developments in microchip design and optical communication controls before it could go mass market.”
