What Is Fiber Internet?

You may have heard the terms fiber-optic internet and fiber internet, but what do they mean? You may know that you get higher speeds, but still wonder what fiber-optic technology is and how it could make your internet service faster. If we break the term apart, we can find the answer. Fiber refers to the glass wires that are inside the cable, also known as fiber-optic cables. Optic refers to how the data is transferred—through light signals. And the internet is, well, you know, the internet. So fiber-optic internet is the transfer of data by light signals through thin, protected glass wires that could give you access to the internet at a much faster rate.

How Fast Is Fiber Fast?

Technology has come far in our lifetime. Fiber used to only mean what your body takes in to maintain regularity as food passes through the digestive system. Now, people associate it with high-speed internet, giving them the fastest connection possible. But what makes fiber so fast?

Back when traditional wires ruled the world and DSL was all that was available, speeds had to rely on passing through copper cables to transmit data. These cables were intended for vocal transmissions initially, so how much data could also pass through is limited. Rather than using photons like fiber-optics does to carry communication, copper cables use electrons which use electrical pulses to communicate. These pulses are subjected to throttling in an already crowded connection.

Photons, on the other hand, transmit using infrared laser light, and since the speed of light is faster, more data can get through, and the bandwidth is higher. Speed with fiber-optics can vary by provider, but generally overall you'll have generally have a better connection using fiber-optics
