Wednesday, April 24, 2013 at 7:20AM Technology briefing: ROADMs and amplifiers
Oclaro announced an add/drop routing platform at the recent OFC/NFOEC show. The company explains how the platform is driving new arrayed amplifier and pumping requirements.

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”
Sultan Dawood, Cisco
Friday, January 11, 2013 at 10:05AM Flexible switching of high capacity traffic carried over ’super-channel' wavelengths is the goal of the European Commission Seventh Framework Programme (FP7) research project.
Wednesday, December 12, 2012 at 6:48AM Transmode has enhanced its metro and regional network equipment to address the operators' need for more efficient and cost-effective packet transport.
“Native Packet Optical 2.0 extends what the infrastructure can do, with operators having the option to use MPLS-TP, Carrier Ethernet 2.0 and OTN, making the network much more service-aware”
Jon Baldry, Transmode
Friday, January 13, 2012 at 1:12PM A Q&A with Andrew Schmitt (@aschmitt), directing analyst for optical at Infonetics Research.
"40Gbps has even less value in the metro than in the core"
Andrew Schmitt, Infonetics Research
Monday, December 19, 2011 at 6:25PM Gazettabyte asked industry analysts, CEOs, executives and commentators to reflect on the last year and comment on developments they most anticipate for 2012. Here are the views of Verizon's Glenn Wellbrock, Professor Rod Tucker, Ciena's Joe Berthold, Opnext's Jon Anderson, NeoPhotonics' Tim Jenks and Vladimir Kozlov of LightCounting.
Glenn Wellbrock, Verizon's director of optical transport network architecture & design
The most significant accomplishment from an optical transport perspective for me was the introduction of 100 Gigabit into Verizon's domestic - US - network.
"The key technology enabler in 2012 will be the flexible grid optical switching that can support data rates beyond 100 Gigabit"
Tuesday, December 13, 2011 at 8:28AM Next-generation reconfigurable optical add/ drop multiplexers (ROADMs) will perform an important role in simplifying network operation but optical component vendors making the core component - the wavelength-selective switch (WSS) - on which such ROADMs will be based should expect a limited return for their efforts.
"[Component suppliers] are going to be under extreme constraints on pricing and cost"
Sterling Perrin, Heavy Reading
