Once the pulses reach their destination,

The Last Mile
Once the pulses reach their destination, an optical network terminal (ONT) converts the light pulses into electrical Ethernet. This is how light becomes something you can use to actually connect your devices to the Internet.

 This conversion happens at the end of the Last Mile, which isn’t actually a mile at all, but a term for the last stretch of fiber that connects the consumer to the backbone of the Internet.

The backbone of the Internet is what makes it possible for people across the globe to connect via the web, and most of it is made of fiber optic cables. Fiber optic Internet may seem like brand new technology, but it has actually been around since the early days of the Internet.

In 1988 fiber optic cables were laid under the ocean to connect the U.S. and Europe. They were the first submarine lines to be laid, and today they have expanded to crisscross the entirety of the ocean floor.

The backbone is the core of the Internet. The instant you connect to a website, no matter the device or the destination, multiple steps are being taken to bring you there, and every one of them is connected by the backbone.
