Uses of Fiber Optics:More Like, What DON'T We Use it For?
05/01/232
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.

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.
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.
