Is There a Difference Between Ethernet and Fiber?

The idea of trying to read the state of a light or even a bit at that frequency, it's something we can't even begin to understand. No one uses hundred megabits anymore. But you want to rock it.

We call it an ethernet cable and so we start to think of that cable as like ethernet is the cable, right? It's the physical medium.
