Wednesday, July 17, 2013 at 7:42AM Infinera announced that TeliaSonera International Carrier (TSIC) is extending the use of its DTN-X to its European network, having already adopted the platform in the US. Infinera has also outlined the next evolution in its networking strategy, dubbed the Intelligent Transport Network.

Ciena has enhanced its packet-optical equipment portfolio by adding packet support to its flagship 6500 platform.
Cards and software from Ciena's established Carrier Ethernet packet platforms have been added to the 6500, a packet-optical platform that features reconfigurable optical add-drop multiplexing (ROADM), WaveLogic3 coherent transponders, Optical Transport Network (OTN) switching and SONET/SDH aggregation.
Friday, June 28, 2013 at 6:48AM Gazettabyte asked its Facebook followers if there is a textbook they value more than others, and why.
It could be a book from student days or a more recent one, work-related. Also asked were readers' interest and experiences with newer styles of learning - online, and books with interactive elements and accompanying websites. Books here include business and technology titles.
Wednesday, June 19, 2013 at 2:28PM u2t Photonics announced recently a balanced detector that supports 64Gbaud. This promises coherent transmission systems with double the data rate. But even if the remaining components - the modulator and DSP-ASIC capable of operating at 64Gbaud - were available, would such an approach make sense?
Gazettabyte asked system vendors Transmode and Ciena for their views.
Tuesday, June 11, 2013 at 10:27AM Arista Networks' latest 7500E switch is designed to improve the economics of building large-scale cloud networks.
The platform packs 30 Terabit-per-second (Tbps) of switching capacity in an 11 rack unit (RU) chassis, the same chassis as Arista's existing 7500 switch that, when launched in 2010, was described as capable of supporting several generations of switch design.
"The CFP2 is becoming available such that by the end of this year there might be supply for board vendors to think about releasing them in 2014. That is too far off."
