This, says the lead editor, Professor Ioannis Tomkos at the Athens Information Technology Center, is a first in the journal's 100-year history.  The issue, entitled The Evolution of Optical Networking, will be published in either April or May and will have a dozen invited papers. 

 

One topic that will change the way we think about optical networks is flexible or elastic optical networks.

The acquisition gives the Chinese system vendor a wealth of optical component expertise and access to advanced European Union R&D projects.

"By acquiring CIP and integrating the company’s R&D team into Huawei’s own research team, Huawei’s optic R&D capabilities can be significantly enhanced," says Peter Wharton, CEO at the Centre for Integrated Photonics (CIP). CIP Technologies is the trading name of the Centre for Integrated Photonics. 

 

 Huawei now has six European R&D centres with the acquisition of CIP.

SK Telecom has developed an enhanced mobile broadband service that combines two networks: 3G and Wi-Fi or Long Term Evolution (LTE) and Wi-Fi. The mobile operator will launch the 3G/ Wi-Fi heterogeneous network service in the second quarter of 2012 to achieve a maximum data rate of 60 Megabits-per-second (Mbps), while the LTE and Wi-Fi integrated service will be offered in 2013, enabling up to a 100Mbps wireless Internet service.

Despite rapid increases in the transceiver speeds of field-programmable gate arrays (FPGA), the transition to optical has begun.

FPGA vendors Xilinx and Altera have increased their on-chip transceiver speeds four-fold since 2005, from 6.5Gbps to 28Gbps. But signal integrity issues and the rapid decline in reach associated with higher speed means optics is becoming a relevant option.]]>Is wireless becoming a valid alternative to fixed broadband?http://www.gazettabyte.com/home/2012/1/10/is-wireless-becoming-a-valid-alternative-to-fixed-broadband.htmlRoy Rubenstein2012-01-10T08:59:16ZDSL LTE LTE Advanced Mark Heath PON The Economist Unwired Insight WiMAX2 gazettabitsAre wireless technologies such as Long Term Evolution (LTE) and WiMAX2 closing the gap on fixed broadband? 

A recent blog by The Economist discussed how Long Term Evolution (LTE) is coming to the rescue of one of its US correspondents, located 5km from the DSL cabinet and struggling to get a decent broadband service. 

 

Peak rates are rarely achieved: the mobile user needs to be very close to a base station and a large spectrum allocation is needed.
