Graham Bell experimented with transmitting voice
signals over optical “beams”, so it's fitting that one of
the first uses of fiber optics was the telephone. Today,
that technology has revolutionized long distance calls.
Military: They offer better performance, more
bandwidth, and greater security for their signals - all at
a lower cost. They're strong, and more importantly
lightweight, and can also be used outdoors in harsh
environments.

Transportation: “smart highways” have begun to
adopt fiber into things like automated toll booths, traffic
signals, and message signs that are changeable. One
such example can be found in electric trains. Fiber is
used as the transmission medium to control the
switching of power semiconductors within the converters
that create the right frequency and voltage for the
electrical drive motors and electrical systems.
UAVs & Drones: the ability to provide a fast and
efficient way to transmit a large amount of data over
long distances, fiber is utilized as the main
communication conduit between the UAV and ground
control.
4. Fiber in New Technologies:

First processor that uses light for ultrafast communications:
this marks the next step in the evolution of fiber optic communication
technology by integrating into a microprocessor the photonic
interconnects, or inputs and outputs (I/O), needed to talk to other
chips.
Greater bandwidth with less power Compared with
electrical wires, fiber optics support greater bandwidth,
carrying more data at higher speeds over greater distances
with less energy. While advances in optical communication
technology have dramatically improved data transfers
between computers, bringing photonics into the computer
chips themselves had been difficult.
5. More new Tech. in Fiber:
donut-shaped laser light beams called optical vortices,
in which the light twists like a tornado as it moves along
the beam path, rather than in a straight line.
An emerging strategy to boost bandwidth is to send the
light through a fiber along distinctive paths, or modes,
each carrying a cache of data from one end of the fiber
to the other. Unlike the colors, however, data streams of
1s and 0s from different modes mix together;
determining which data stream came from which source
requires computationally intensive and energy-hungry
digital signal processing algorithms.

- The world's largest fiber-optic local network is going behind the walls at
Sandia National Laboratories in New Mexico.
- The new network works at "10 gigabit-type rates," Sandia
network engineer Steve Gossage said. The
average U.S. connection is just under seven megabits per
second; Google's Fiber project runs at one gigabit per second.
- Optical fibers save electricity by reducing the number of
switches and routers a network needs, a Sandia announcement
explained. Places that use traditional copper wires have
separate networks for their phones, computers, security and
other electronics. With fiber optics, everything can go on one
network, with fewer power-hungry switches.
