How Fiber Optics Work

Google Fiber is fast – so fast that you can upload a full-length HD home movie faster
than it takes to make a bowl of popcorn.  
But what makes it so fast?
Fiber uses light-based optical technology. Light travels along  a fiber-optic cable
in the form of photons, or particles of light. Frequency signals are encoded into the pulses
of light so a computer can translate the signals into data.
Since Fiber relies on beams of light, it’s less susceptible to noise and interference
than other data-transfer mediums such as copper wires or telephone lines. Unlike wires and
lines that have limited capacity, fiber optics are capable of transmitting billions of digital
bits per second.
Because of fiber optic technology, every home with Google Fiber installed has a symmetric
connection to the Fiber backbone. In other words, all connections are equally fast.
Because the cables are fragile and need to be installed with care, the lines are difficult,
expensive and time-consuming to build.
But because of this incredible technology and the careful execution of this new network,
Google Fiber is an investment in your home. We believe that installing Fiber will increase
your property value - and once it’s installed, it’s yours.
More importantly, it’s an investment in your community. When you bring the infrastructure
into your neighborhood, you’re helping to connect schools, hospitals, and libraries
free of charge. Think of it like bringing more light into your community - and more
