Modal bandwidth
Modal bandwidth is like the number of people that can fit in a narrow hallway without bumping into each other. Let's say you have a hallway that's really skinny and only fits one person at a time. That's like having a small modal bandwidth. Only one 'mode' or way of light can fit through at a time without interfering with other 'modes' of light.
But if you have a wider hallway, more people can walk through at the same time and not bump into each other. That's like having a larger modal bandwidth. This means that more 'modes' of light can travel through the fiber optic cable at the same time without interfering with each other.
Basically, modal bandwidth measures how much data can go through a fiber optic cable at the same time without getting mixed up. The wider the bandwidth, the more data it can handle without getting messy!
