How does light-based data transmission work? Fiber optics?

865 views

This is specifically in reference to Starlink satellites. I have no idea how they could possibly work. How can thousands of videos, pictures, text, and music, be sent optically through space? I feel like it’s an impossible amount of data to transmit, other than the use of magic.

From my physics textbook:

> […], consider modulating (modifying) the wave by chopping off some of the wave crests. Suppose each crest represents a binary digit, with a chopped-off crest representing a zero and an unmodified crest representing a one.

So light is a wave and they can modify the way so that there is a binary signal.
