NeoPhotonics samples its first CFP-DCO products

NeoPhotonics has entered the fray as a supplier of long-distance CFP pluggable modules that integrate the coherent DSP-ASIC chip with the optics. 

The company has announced two such CFP Digital Coherent Optics (CFP-DCO) modules: a 100 gigabit-per-second (Gbps) module and a dual-rate 100Gbps and 200Gbps one.

“Our rationale [for entering the CFP-DCO market] is we have all the optical components and the [merchant coherent] DSPs are now becoming available,” says Ferris Lipscomb (pictured), vice president of marketing at NeoPhotonics. “It is possible to make this product without developing your own custom DSP, with all the expense that entails.”

Books of the year 2016 - Part 2

More industry figures comment on books read this year. Here are Finisar's Simon Poole's and Ciena's Loudon Blair's recommendations.

Simon Poole, director, new business ventures, Finisar Australia

The highlight of the year in fiction was reading The Shepherds’ Crown, the last of the Discworld novels from the wonderful Terry Pratchett. He, along with his cast of extraordinary characters, including the marvellous Tiffany Aching – a fabulous role model for teenage girls, held up a mirror to the foibles and strengths of our humanity, and will be sorely missed.

Infinera unveils first platforms using its latest PIC & DSP  

  • The Cloud Xpress 2 platform for data centre interconnects packs 1.2 terabits in a 1 rack unit (1RU) box.  
  • Infinera has also unveiled two DTN-X XT 'meshponder' platforms that aggregate client signals and offer sliceable transponder functionality that delivers wavelengths to multiple destinations. 
  • The company also announced an open flexible grid line system that supports the C and L bands 
  • Three of the top four US internet content providers are Infinera customers.

Infinera has started to unveil its platform portfolio based on its Infinite Capacity Engine that combines the company's latest-generation photonic integrated circuit (PIC) and coherent DSP-ASIC technology.

The first platform using the technology is the Cloud Xpress 2, Infinera second-generation data centre interconnect platform, was unveiled in September. More recently, it has added two DTN-X meshponder platforms - the XT-3300 and the XT-3600 - as well as upgrading two of its existing DTN-X platforms.

Books of the year 2016 - Part 1

Each year Gazettabyte asks industry figures to comment on books that they recommend. Here are BT's Andrew Lord's and Cignal's Andrew Schmitt's recommendations to kick off this year's reviews.

 

Andrew Lord, Head of Optical Research at BT.

Quantum technologies are flavour of the month, with huge government investments from around the world. The title and cover of Bananaworld: Quantum Mechanics for Primates by Jeffrey Bub, suggest a book that will ‘unpeel’ a tough but increasingly important subject for general readers. 

The book itself is, however, far deeper than its cover suggests, going way beyond the basics, and attempting to forge a link between quantum mechanics and the structure of information.

DIMENSION tackles silicon photonics’ laser shortfall

Ambitious European project seeks to combine lasers, electronics and photonics, all on one chip

Several companies and research institutes, part of a European project, are developing a silicon photonics process that combines on-chip electronics and lasers. Dubbed Dimension (Directly Modulated Lasers on Silicon), the silicon photonics project is part of the European Commission’s Horizon 2020 research and innovation programme.

Ciena brings data analytics to optical networking 

  • Ciena's WaveLogic Ai coherent DSP-ASIC makes real-time measurements, enabling operators to analyse and adapt their networks.     
  • The DSP-ASIC supports 100-gigabit to 400-gigabit wavelengths in 50-gigabit increments. 
  • The WaveLogic Ai will be used in Ciena’s systems from 2Q 2017.  

Ciena has unveiled its latest generation coherent DSP-ASIC. The device, dubbed WaveLogic Ai, follows Ciena’s WaveLogic 3 family of coherent chips which was first announced in 2012. The Ai naming scheme reflects the company's belief that its latest chipset represents a significant advancement in coherent DSP-ASIC functionality.  

Helen XenosThe WaveLogic Ai is Ciena's first DSP-ASIC to support two baud rates, 35 gigabaud for fixed-grid optical networks and 56 gigabaud for flexible-grid ones. The design also uses advanced modulation schemes to optimise the data transmission over a given link.

Perhaps the most significant development, however, is the real-time network monitoring offered by the coherent DSP-ASIC. The data will allow operators to fine-tune transmissions to adapt to changing networking conditions.

Talking markets: Oclaro on 100 gigabits and beyond  

Oclaro’s chief commercial officer, Adam Carter, discusses the 100-gigabit market, optical module trends, silicon photonics, and why this is a good time to be an optical component maker.

Oclaro has started its first quarter 2017 fiscal results as it ended fiscal year 2016 with another record quarter. The company reported revenues of $136 million in the quarter ending in September, 8 percent sequential growth and the company's fifth consecutive quarter of 7 percent or greater revenue growth.

Adam CarterA large part of Oclaro’s growth was due to strong demand for 100 gigabits across the company’s optical module and component portfolio.

The company has been supplying 100-gigabit client-side optics using the CFP, CFP2 and CFP4 pluggable form factors for a while. “What we saw in June was the first real production ramp of our CFP2-ACO [coherent] module,” says Adam Carter, chief commercial officer at Oclaro. “We have transferred all that manufacturing over to Asia now.”
