Optoelectronics

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.

The need for speed

Are connectors meeting the demands of an industry wide requirement for high speed interfaces? By Vanessa Knivett.

Code calling

Choosing between hardware and software modems means managing cost and risk. By Paul Brown.

Get it out of here!

Serial doesn’t necessarily mean simpler, as data transfer rate remains the dominating factor in I/O. By Philip Ling.

Voice in the wilderness?

As IP networks take on more voice traffic, the rise of IP telephony should have a profound effect on technology developments. By Jim Chalmers.

A tangled web

A web of multi source agreements threaten to engulf 10Gbit transceiver modules. By John Walko.

Let’s get physical

As the communications industry – whether wired or wireless – strives towards ever higher data rates, the role of physical layer (PHY) devices is becoming increasingly important and, in some instances, contentious. It’s not surprising that the range of technologies, architectures and design options being offered is becoming increasingly complex. With Gigabit Ethernet and 10Gbit Ethernet gaining momentum, most competition will be played out in these sectors. PHYs basically provide access to the Media Access Control (MAC) layer through a management interface. If you consider high data rate optical links, such as Gigabit Ethernet, the PHY chip is really a mux/demux combination that acts as a liaison between optics and electronics, such as the framer.
