Fiber Internet is the latest change to the way data is transferred around the globe. It’s much faster than cable, way faster than dial-up, and can carry large amounts of data in a single line, often reaching multiple terabits of data transfer fairly easily.

Before Fiber: DSL and Cable

Digital Subscriber Line (DSL) used the existing telephone lines to transmit data, which were usually made of copper.

DSL is slow, old, and has been phased out for the most part in favor of cable, but it remains in some rural areas. The average speed for DSL is around 2 Mbps.

Cable internet uses coaxial cable, also made from copper, and is generally bundled with the same cables used to run the television network. This is why many ISPs offer bundled plans with a TV subscription and Internet Access. The average speed for cable varies but ranges from around 20 Mbps to 100 Mbps

The Fiber Revolution

Fiber optic cables use small glass fibers to transmit data using pulses of light. The light travels much like electricity would through a copper wire, but the advantage is that fiber cables can carry multiple signals at once. They’re incredibly small, so they’re often bundled into larger cables called “fiber optic trunk cables,” each containing multiple fiber lines. Fiber cables carry huge…
