STMicro chooses PSM4 for first silicon photonics product

STMicroelectronics has revealed that its first silicon photonics product will be the 100 Gigabit PSM4. The 500m-reach PSM4 multi-source agreement (MSA) is a single-mode design that uses four parallel fibres in each direction. The chip company expects the PSM4 optical engine to be in production during 2015. 

"We have prototypes and can show them running very well at 40 Gig [4x10 Gig]," says Flavio Benetti, group vice president, digital product group and general manager, networking products division at STMicroelectronics. "But it is expected to be proven at 4x25 Gig in the next few months." STMicroelectronics has just received its latest prototype chip that is now working at 4x25 Gig.

Silicon photonics book scheduled for early 2016

Daryl Inniss, practice leader, components at Ovum, and I have started work on a book on silicon photonics. The book, to be written during 2015, will be published by Elsevier.

The work will provide an assessment of silicon photonics and its market impact over the next decade. The title will explore key trends and challenges facing the telecom and datacom industries, provide a history of silicon photonics, and detail its importance. The title will also pinpoint those applications that will benefit most from the technology.

Gazettabyte hopes to share some of the insights and information gathered during the writing of the book. And if this book project is of interest, please feel free to contact us. 

ECOC reflections: final part

Gazettabyte asked several attendees at the recent ECOC show, held in Cannes, to comment on key developments and trends they noted, as well as the issues they will track in the coming year.

With ECOC 2014 celebrating its 40th anniversary, the technical programme committee did its best to mark the occasion. For example, at the anniversary symposium, notable speakers presented the history of optical communications. Actual breakthroughs discussed during the conference sessions were limited, however.

It appears that after 2008 to 2012, a period of significant advancements, the industry is now more mainstream, and significant shifts in technologies are limited. It is clear that the original focus four decades ago on novel photonics technologies is long gone. Instead, there is more and more of a focus on high-speed electronics, signal processing algorithms, and networking. These have little to do with photonics even if they greatly improve the overall efficient operation of optical communication systems and networks.

Infinera targets the metro cloud

Infinera has styled its latest Cloud Xpress product used to connect data centres as a stackable platform, similar to how servers and storage systems are built. The development is another example of how the rise of the data centre is influencing telecoms.

"There is a drive in the industry that is coming from the data centre world that is starting to slam into the telecom world," says Stuart Elby, Infinera's senior vice president of cloud network strategy and technology.

Ranovus readies its interfaces for deployment

• Products will be deployed in the first half of 2015
• Ranovus has raised US $24 million in a second funding round
• The start-up is a co-founder of the OpenOptics MSA; Oracle is now also an MSA member.

Ranovus says its interconnect products will be deployed in the first half of 2015. The start-up, which is developing WDM-based interfaces for use in and between data centres, has raised US $24 million in a second stage funding round. The company first raised $11 million in September 2013.

Saeid Aramideh"There is a lot of excitement around technologies being developed for the data centre," says Saeid Aramideh, a Ranovus co-founder and chief marketing and sales officer. He highlights such technologies as switch ICs, software-defined networking (SDN), and components that deliver cost savings and power-consumption reductions. "Definitely, there is a lot of money available if you have the right team and value proposition," says Aramideh. "Not just in Silicon Valley is there interest, but in Canada and the EU."

ECOC 2014: Industry reflections on the show

Gazettabyte asked several attendees at the recent ECOC show, held in Cannes, to comment on key developments and trends they noted, as well as the issues they will track in the coming year.

 It took a while to unwrap what happened at ECOC 2014. There was no one defining event or moment that was the highlight of the conference.

The location was certainly beautiful and the weather lovely. Yet I felt the participants were engaged with critical technical and business issues, given how competitive the market has become.

How Oclaro's CTO keeps on top of the data deluge

Being creative, taking notes, learning and organising data are challenges that all company executives and engineers face. Andy Carter, CTO of Oclaro, is renown for his sketched diagrams and his ability to explain stuff. Gazettabyte asked him to share his experiences and thoughts on the matter.

Andy Carter, CTO

"To be honest, I am an absolutely terrible note-taker. I always have been. At university, I could either listen to a lecture and try and understand it or take notes. I couldn’t do both.

If I did manage to take some notes, I rarely looked at them afterwards or found them useful.

At conferences, in the days of printed outlines, I’d make a few comments in the margins or underline items, but rarely in a separate notebook.
