Free space optics to speed stock exchange

Data transmitted between the data centres of the New York Stock Exchange (NYSE) and Nasdaq will soon be made by a laser network, which is due to be switched on in March.

Chicago-based Anova, a low-latency network and optical engineering firm, has set up the laser network that covers the 35 miles between the data centres of the NYSE in Mahwah, New Jersey and those of Nasdaq in Carteret, NJ.

Coriant and Juniper collaborate to increase network capacity

Coriant, a supplier of metro-to-core transport solutions, has announced the latest progress in its collaboration with Juniper Networks to create an integrated packet transport network (IPTN).

Recent joint R&D between the two networking innovators resulted in the first multi-vendor line side interworking between router and DWDM system suitable for long haul (LH) transmission.

Guidance for network disaster damage

Natural and human-caused disasters can damage or destroy data and communications networks – and several presentations at the 2014 OFC Conference and Exposition next week in San Francisco will present information on strategies that can mitigate the impacts.
 
Disasters such as earthquakes, tornadoes, or even terrorist attacks, can damage data centres and the communication links between them, causing massive losses in data and costly disruptions.
 

Alcatel-Lucent and BT announce 1.4Tb/s trials

Alcatel-Lucent and BT have announced trial speeds of up to 1.4Tb/s with a record spectral efficiency of 5.7 bits per second per Hertz (b/s/Hz) on an existing core fibre connection. The companies say this is believed to be the fastest speed ever achieved in commercial grade hardware in a real-world environment, and is equivalent to transmitting 44 uncompressed HD films in a single second.

CES award for Zyxel Communications

Zyxel Communications has won an award for its its indoor Gigabit Passive Optical Network (GPON) broadband gateway with voice and wireless IPTV.

The product has been named a CES Innovations 2014 Design and Engineering Honoree in the Home Networking Product category at the prestigious 2014 International CES show in Las Vegas, Nevada.

Innovative instrument distinguishes individual stars

In December’s issue of the journal Astronomy & Astrophysics, astronomers from the University of California in the USA reported that a new instrument combining adaptive optics and interferometry, facilitated by the use of fibre optic cables, has distinguished individual stars in a nearby star system for the first time. This demonstrates promise for eventually identifying planets around other stars in the universe.

Swiss researchers increase capacity by minding the gap

Scientists from the École polytechnique fédérale de Lausanne (EPFL) in Switzerland have shown how to achieve a dramatic increase in the capacity of optical fibres. The solution, published in Nature Communication's December issue, reduces the amount of space required between the pulses of light that transport data.      

New fibre 'the foundation for future internet infrastructure'

Researchers from the University of Bristol, in collaboration with the National Institute of Information and Communications Technology (NICT) in Japan, say they have developed a new type of optical fibre that will become the 'foundation for future internet infrastructure'.

The teams say their advanced multicore fibre-based network will overcome critical capacity barriers, which threaten the evolution of the internet.

Faster optical communications on the wings of a butterfly

Laser nano-technology has been used to create a device smaller than a human hair, in an effort to make optical communication faster and safer.

Researchers from Swinburne University of Technology in Australia and Friedrich-Alexander Universität Erlangen-Nürnberg in Germany mimicked microscopic structures on the wings of a butterfly to create the photonic crystal which can split both left and right circularly polarised light.

Software-defined networking gets boost from Ciena

The network specialist, Ciena Corporation is building a software-defined, multi-layer wide area network (WAN), in collaboration with with CANARIE, Internet2 and StarLight to boost confidence in the technology of software-defined networking (SDN).
