Fiber Optic Internet
What is fiber optic internet?
Fiber optic internet is a data connection carried by a cable filled with thin glass or plastic fibers. Data travels through them as beams of light pulsed in a pattern. Fiber optic internet speeds are about 20 times faster than regular cable at 1 Gbps.
Why is fiber optic cable internet so much better than plain ol’ cable internet? Because there’s no copper wire to gum up the works. Cable internet sends its signals down metal wires. The metal heats up, weakening the signal and picking up interference. That’s why cable and DSL internet are so much slower and clumsier than fiber optics [1].
How fiber optic internet works
Fiber optic internet works by splitting files like movies and games into data packets of zeroes and ones. A laser flashes this Morse code-type signal into one end of a plastic or glass filament. The “wire” is about as thick as one strand of human hair.
A special sheath called a cladding keeps the beam of light inside the filament. It bounces off the walls for as far as 60 miles and pops out the other end where a modem decodes the light into a form your computer can use.
3 types of fiber optic cable internet
There are three types of fiber optic cable internet, ranging from “whoa, I can’t believe how fast this is” to “okay, this is not much better than regular cable.” The fiber optic internet speed delivered by each depends heavily on how far the fibers make it toward your modem.
- FTTH or FTTP: “Fiber To The Home” or “Premises.” This is the fastest, most reliable fiber optic connection because the fibers come straight to your door
- FTTC: “Fiber to the Curb.” This gets the fiber to the utility pole outside your house, but uses coaxial cable from there. The short length of copper wire is a bottleneck
- FTTN: “Fiber To The Node” or “Neighborhood.” The fiber optics get to within one mile of your house. A longer trip through metal wires make this the slowest of the three options [2]
