Sunday, February 10, 2013 at 9:09AM Network optimisation continues to exercise operators and content service providers as their requirements evolve with the growth of services such as cloud computing. Cisco Systems' announced elastic core architecture aims to tackle networking efficiency and address particular service provider requirements.
“The core [network] needs to be more robust, agile and programmable”

Monday, October 1, 2012 at 2:44PM JDSU's CTO for communications and commercial optical products, Brandon Collings, discusses reconfigurable optical add/drop multiplexers (ROADMs), 100 Gigabit, silicon photonics, and the status of JDSU's tunable SFP+.
"We have been continually monitoring to find ways to use the technology [silicon photonics] for telecom but we are not really seeing that happen”
Brandon Collings, JDSU
Wednesday, August 15, 2012 at 7:23PM AppliedMicro has announced the first CMOS merchant multiplexer chip for 100Gbps coherent optical transmission. The S28032 device supports dual polarisation, quadrature phase-shift keying (DP-QPSK) and has a power consumption of 4W, half that of current multiplexer chip designs implemented in BiCMOS.

Friday, May 4, 2012 at 3:41PM Gazettabyte asked ADVA Optical Networking, Ciena, Cisco Systems and Ovum about their impressions following the recent OFC/NFOEC 2012 exhibition and conference.
OFC/NFOEC reflections: Part 2
"As the economy continues to navigate its way through yet another very difficult period, it was good to see so many companies innovating and introducing solutions."
Massimo Prati, Cisco Systems
Wednesday, April 11, 2012 at 5:37PM Gazettabyte went to visit Professor Dan Sadot, academic, entrepreneur and founder of chip start-up MultiPhy, to discuss his involvement in start-ups, his research interests and why he believes coherent technology will not only play an important role in the metro but also the data centre.
"Moore's Law is probably the most dangerous enemy of optics"
Professor Dan Sadot
Thursday, March 29, 2012 at 10:01AM Oclaro has announced its plan to merge with Opnext. The deal, valued at US $177M, will result in Opnext's shareholders owning 42% of the combined company. The merger of the fifth and sixth largest optical component players will create a company with annual revenues of $800M, second only to Finisar. The deal is expected to be completed in the next 3-6 months.

Thursday, March 22, 2012 at 7:10AM More vendors are coming to market with 100 Gigabit direct detection products for metro and private networks.
The emergence of a second de-facto 100 Gigabit standard, a complement to 100 Gigabit coherent, gained credence with 4x28 Gigabit-per-second (Gbps) direct detect announcements from Finisar and Oclaro and likely backing from system vendor, ECI Telecom.
"We believe that in some cases operators will prefer to go with this technology instead of coherent"
Shai Stein, CTO, ECI Telecom
