Pointy pulses improve optical fiber throughput by a factor of 10

By - December 5, 2013 2 Pictures
As the volume of data carried around the world via optical fibers continues to increase, researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) have found a way to increase data throughput capacity by ten times. Because it is based on changing the shape of light pulses to reduce the space between, the breakthrough would work on existing optical fiber infrastructure. Read More

Fiber optics on the right wavelength to prevent rail accidents

By - October 2, 2013 1 Picture
A team from the Hong Kong Polytechnic University is to release details of a seven-year program to monitor a 36-km stretch of high-speed rail line using a series of special fiber optic sensors . According to a press release put out by the Optical Society, the system has detected "anomalous vibrations" on 30 occasions, allowing the early rectification of emerging problems that could conceivably have gone on to cause rail accidents.

Closing the gap to improve the capacity of existing fiber optic networks

By - April 7, 2013 2 Pictures
A team of researchers working through Australia’s Centre for Ultrahigh Bandwidth Devices for Optical Systems (CUDOS) has developed data encoding technology that increases the efficiency of existing fiber optic cable networks. The researchers claim their invention increases the data capacity of optical networks to the point that all of the world’s internet traffic could be transmitted via a single fiber. Read More

Corning introduces laser fiber optic USB cable

By - January 9, 2013 2 Pictures
Digital systems are notorious for bottlenecks. It’s no good having a blazing, overclocked PC and an internet connection like a firehose if the USB cable between them is like a straw. It’s even worse when the distance between PC and modem is more than a few feet away, so the cable can’t reach. With the aim of eliminating these bottlenecks, Corning Cable Systems LLC is unveiling its Optical Cable by Corning at CES in Las Vegas. These cables replace copper wires with fiber optics to produce cables up to 100 meters (328 ft) long, that are much more durable and achieve speeds of 10 gigabits per second, which is enough to load a full-length HD video in 30 seconds.

New type of optical fiber could be used in photovoltaic fabrics

By - December 10, 2012 2 Pictures
Imagine forgetting to plug in your smartphone, but then not worrying because your clothes could charge it for you. It sounds surreal, but it may one day be reality. An international team of scientists and engineers led by John Badding, a professor of chemistry at Penn State University, have developed a silicon-based optical fiber that acts like a solar cell and offers the promise of fabric that can generate electricity from light.

Data transmission speed of 2.56 Tb/s achieved by twisting beams of light

By - June 26, 2012 1 Picture
Thankfully, data transmission speeds have come a long way since the days of dial-up when users would have plenty of time to twiddle their thumbs as they waited for an image or MP3 to make its way to their hard drive. These days, broadband cable currently supports speeds of around 30 megabits per second, which is a hell of an improvement. Now researchers have outdone that by a factor of around 85,000 by using twisted beams of light to transmit data at up to 2.56 terabits per second. Read More

Experimental optical fibers utilize built-in electronics instead of separate chips

By - February 7, 2012 1 Picture
When data is transmitted as pulses of light along a fiber optic cable, chips at either end of that cable must convert the data from and back into an electronic signal - this is what allows an outgoing video image to be converted into light pulses, then back into video at the receiving end, for instance. There are a number of technical challenges in coupling chips to fibers, however. Now, an international team of scientists are developing an alternative ... fiber optics with the electronics built right into the fiber. Read More
