What are fiber optic networks?

Fiber optic networks are built with thin strands of glass about the width of a human hair that is wrapped in a protective rubber cladding. Lasers are used to transmit information across those cables. These networks provide the foundation for the internet that connects the world and enable the applications and methods of communication we enjoy today, such as phone calls, video conferencing, streaming videos, and social media. Now, people can connect to the network using a variety of different methods – mobile, cable, DSL, or WiFi – which all use either radio or electrical signals to transmit information. But very quickly, all this data is carried to a point in the network where it is aggregated and converted to an optical signal. Fiber optic networks enable the transmission of vastly more information over far greater distances than any other technology. This includes transmission across metropolitan areas and entire continents and even across oceans. Since the inception of fiber optic networks, service providers have deployed more than 5 billion kilometers – that’s enough cable to wrap the earth more than 120,000 times. And you can expect that, as bandwidth requirements continue to go up, we’ll continue to see more and more fiber cables deployed…. including all the way to people’s houses.
