Verizon's fiber-optic network Here I am Ashwani and here's my brief description on Fios network. It simply stands for fiber-optic service. And in Irish, "Fios" means knowledge. Fiber optics is the transmitting of light through small fiber-like strands of glass and sometimes plastic. These fiber optic cables have data transmitted down at a much faster rate and with less signal loss since they aren't susceptible to electromagnetic interference. 
 
It's actually pretty incredible how these cables work -- They're made by taking the glass, sometimes plastic and pulling it through machines, which becomes a long strand that is slightly thicker than that of a human hair. Through this light will be transmitted with impulses similar to how electricity is transmitted, impulses down the copper wires. This is then wrapped in a cladding that makes sure the light reflects back and forth within the glass strand and continues to move forward instead of refracting out of the core and just being lost. So we have a transmitter at one end that is sending the light signals down the cable from the data it receives bouncing around but always moving forward within that cable. And then we have a receiver on the other end, and then decoding them into data again. 
 
It's similar in the way that copper cables work in terms of sending receiving, but there's a bunch of benefits to using fiber optics over copper. 
So what are the benefits of Fios to you and me? Well, firstly, what most of us probably care about, especially myself is 'speed' because of the way information is transmitted through the fiber optic cable. It is a much higher theoretical data rate than traditional coaxial or phone lines. 
 
The plans Verizon offers right now, for example -- 100 megabits per second download and upload, which is already crazy fast, 300 megabits per second down and upstream. And what I have personally, which is crazy fast speeds up to nine hundred and forty megabits per second down and eight hundred and eighty megabits per second up over Wi-Fi. That's crazy speed. Also, it's important to note the fact that these don't just download speed that is used for streaming things, etc. It also has uploading speed, which is important for gaming.  
 
And who doesn't like good cable management?  right, so Fios probably sounds too good to be true at this point. Well, there is one downside that it isn't available in a lot of places. Today companies are still trying to roll out the fiber optic cables as fast as they can since its a newer technology. But when you think about how many miles of cable that is in the streets and then all of the cables in individual buildings as well. It's no surprise why it's so large of a task for these companies and is taking a bit of time to see everywhere. Fios from Verizon is currently available to residential customers living in select areas of New York, New Jersey, Maryland, Virginia, Pennsylvania, Rhode Island, Massachusetts, Connecticut, and Delaware, as well as Washington, DC.
