When it comes to lightning fast data transmission, sealed fiber optics are often to thank. But what are these cables and how do they actually work? Here, we’ll get into the nitty gritty of how fiber optic cables work to help us from day to day.
First, we need to pay attention to the name of the cable. Fiber optics. Part of the explanation is right there! These cables are composed of tiny strands of fiber that use light to transmit information around the world.
Or at least from one end of the cable to the other. It’s pretty simple to perform a test to prove this, too. If you take a fiber optic cable and point a laser down it, you’ll see the light coming through on the other side.
The reason this works is a phenomenon called total internal reflection. This principle guides light and data through these cables in an incredibly fast fashion. This also ensures that all of the data sent through these cables remains intact from its starting point to its ending point.
Fiber optic cables have taken a very simple piece of technology and used it to transform the world. You’re probably using it right now.
