Optoelectronics play a critical role in the electronics industry. At one end, it provides the isolation needed in industrial systems. At the other, optoelectronics enables the transmission of data around the world using fibre optic cables.

In this section, New Electronics keeps visitors up to date with developments in the optoelectronics market, covering topics ranging from optocouplers to lasers to infrared emitters.

Applied Micro reaps the benefits of X-Gene ARMv8 processors

In 2010, Applied Micro made a strategic decision; courageous or foolhardy, depending upon where you sat in the communications processor world. That decision was to sign an architectural licence for ARM's 64bit v8 processor cores and to embark on the design of a multicore device.

Fibre optic networks can provide the platform for security and monitoring

'Linear assets' is a term that covers anything from roads and railway to pipes and perimeter fences. Typically, these assets will have signage, sensors and equipment controlled from a single point somewhere along that asset, and that control data is transmitted through fibre optic cables These cables can also be used to provide low cost and accurate monitoring.

NFC yet to secure its role in securing mobile payments

Novel approaches, such as Host Card Emulation (HCE) and potential threats such as the emergence of Bluetooth Low Energy – another technology standard for exchanging data wirelessly over very short distances – have brought into sharp focus the disappointing pace of development of mobile Near Field Communications (NFC), notably for financial transactions.

DSL technology could allow data to be sent to the home at 1Gbit/s

Once the plain old telephone service, the role of the telephone wire continues to be refashioned. The latest digital subscriber line (DSL) standard being developed – G.fast – uses 106MHz of phone wire spectrum to deliver gigabit broadband, a far cry from its original purpose of carrying a 3kHz voice call. The developments (see fig 1) complement fibre getting ever closer to the home.

Ethernet finds use in the automotive industry

The automotive industry is turning to Ethernet to address high-bandwidth applications emerging within the car. But it is Ethernet with a twist, tailored to meet the stringent requirements of the car. And while automotive Ethernet is taking to the road, the technology has yet to achieve widespread industry backing.

Test equipment helps embedded system designers debug their rf connectivity

It wasn't too long ago that wireless communication was only available using devices designed solely for that purpose; walkie-talkies and the like. But over the last few years, wireless communication has found its way into all manner of products. Today, providing the ability for a product to communicate via Wi-Fi, gsm or other rf technologies is almost expected. What might once have been pretty much a digital design is now more complex – and the tools needed to design and test these products have had to adapt to new demands.

Joining 50billion dots: The evolution of the Internet of Things

The Technology Strategy Board recently announced that it is investing up to £4million in a competition that will stimulate the development of an open application and services ecosystem for the Internet of Things. Indeed, with Ericsson predicting there will be 50billion connected devices by the end of the decade, M2M communications technology will certainly have to overcome the challenges regarding scalability and support for new applications.

Meeting the challenges of the data deluge gap

We live in an increasingly connected world, a world generating a massive amount of data that is growing at a faster rate than current investments in IT can support. The difference between the available investment and what is required to support current data growth has given rise to what I call the 'data deluge gap'.

Pushing packet performance: How IP networks are handling ever more data

Internet Protocol (IP) core routers are tasked with moving large amounts of IP traffic across the network backbone, unlike edge routers, which typically aggregate a variety of operator services, such as residential broadband, cellular traffic backhaul and business connectivity. IP traffic in general is growing rapidly: analysts estimate the amount of data is growing by 30% a year.

Design challenges of implementing USB into next generation portable communications hardware

Universal serial bus (USB) interfaces are becoming ever more prevalent in the design of portable communication products, including mobile phones. These interfaces not only offer a means of importing and exporting multimedia data, such as picture or music files, but also present a convenient way of carrying out the charging process. As a result, USB is now being widely tipped to become the ubiquitous interconnect within this sector.

Creating frequency scalable nonlinear transmission line based vector network analysers

High frequency vector network analysers (VNAs) make use of harmonic samplers, or mixers, to down convert measurement signals to intermediate frequencies (IF) before digitising them. Such components play a critical role in VNAs because they set the bounds on important parameters like conversion efficiency, receiver compression, isolation between measurement channels and spurious generation at the ports of a device under test (DUT).
