ECOC 2019 industry reflections II 

Gazettabyte requested the thoughts of industry figures after attending the ECOC show, held in Dublin. In particular, what developments and trends they noted, what they learned and what, if anything, surprised them. Input from II-VI, Ciena, Fujitsu Optical Components and Acacia Communications. The second and final part. 

 

Sanjai Parthasarathi, chief marketing officer at II-VI 

One new theme at ECOC is the demand for lower-cost 100-gigabit coherent transceivers for deployment in optical access for wireless access and fibre-deep cable TV. Such demand would significantly expand the market.

It was noteworthy at the show how 5G has become a significant factor influencing the wireless access market, with the potential for wide deployment of dense wavelength-division multiplexing (DWDM) technology with wavelength switching and tuning functions, not only in traditional network architectures but interesting new ones too.

WaveLogic 5: Packing a suitcase of ideas into 7nm CMOS  

  • Ciena’s WaveLogic 5 coherent digital signal processor family comprises the Extreme and Nano chips
  • The WaveLogic 5 Extreme maximises optical capacity and transmission reach while the Nano is targeted at compact, power-conservative applications

Advancing coherent optical transmission performance to benefit its platforms; targeting the emerging coherent pluggable market opportunity; selling modules directly, and being more vertically integrated. All these aspects were outlined by Cisco to explain its intention to buy the coherent optical transmission specialist, Acacia Communications; a deal set to be completed in the spring of 2020.      

But this also fits the strategy being pursued by Ciena with its next-generation WaveLogic 5 family of coherent DSPs.

 

Kim Roberts

The WaveLogic 5 continues Ciena’s tradition of issuing a coherent digital signal processor (DSP) family approximately every three years: Ciena announced the WaveLogic 3 in 2012 and the WaveLogic Ai in 2016

Ciena has managed to maintain its three-yearly cadence despite the increasing sophistication of each generation of coherent DSP. For example, the WaveLogic 5 Extreme will support 800 gigabits-per-wavelength, double Ciena’s WaveLogic Ai that has been shipping for nearly two years.

Kim Roberts: The 2019 John Tyndall Award winner

A Profile

A conceptualiser, mathematician, furniture maker, prolific inventor, sushi lover, creative spirit, team leader and mentor. These are just some of the descriptors applied to Kim Roberts of Ciena by the people that know him.

Roberts has been awarded the 2019 John Tyndall Award by The Optical Society (OSA) and the IEEE Photonics Society in recognition of his “pioneering contributions to the development of practical coherent communication systems”.

“It is well deserved,” says Seb Savory, who first knew Roberts when they both worked at Nortel and who is now an academic at the University of Cambridge working on joint projects with Ciena. Ciena acquired Nortel in 2010.

Books in 2018 - Part 3

More books read in 2018, as recommended by Steve Alexander and Yves LeMaitre.

Steve Alexander, senior vice president and CTO, Ciena 

I was standing in line at a Starbucks and was chatting with another person who asked what all these engineers were doing talking about networks of submarines. In fact, it was a nearby conference on submarine cables. The person said: “I thought that’s what satellites were for”.

I wanted to find a book I could point people to who think that satellites carry most of the international traffic when, in fact, it is the fibre-optic submarine cables that carry the vast majority of the world’s communications. I came up with The Undersea Network by Nicole Starosielski.

Our industry does such a good job at this that most people don’t even know such networks exist. It is like air; it is there and it works.

Acacia eyes pluggables as it demos its AC1200 module  

The emerging market opportunity for pluggable coherent modules is causing companies to change their strategies. 

Ciena is developing and plans to sell its own coherent modules. And now Acacia Communications, the coherent technology specialist, says it is considering changing its near-term coherent digital signal processor (DSP) roadmap to focus on coherent pluggables for data centre interconnect and metro applications.

Ciena to sell its own coherent modules

The systems vendor is expanding its offerings to include WaveLogic modem chips and coherent optical modules.

Ciena is developing its own coherent modules to sell to the telecom and datacom markets. 

The system vendor has set up the Optical Microsystems Division business unit to promote its WaveLogic coherent modem technology to the marketplace. Until now it has licensed its WaveLogic Ai digital signal processor (DSP) to module makers Lumentum, NeoPhotonics and Oclaro. But now it is planning to sell its own coherent modules.

In a job advert for a head of sales channel development, Ciena says the Optical Microsystems Division's goal is ‘to develop and productize electro-optic components and modules for sale to global systems integrator customers to be incorporated in their products for sale to telecom and data network customers’.

And at the recent European Conference on Optical Communication (ECOC) held in Rome, a network equipment manufacturer said it was approached by Ciena enquiring if it was interested in buying coherent modules from the company.

Ciena picks ONAP’s policy code to enhance Blue Planet  

Ciena is adding policy software from the Linux Foundation’s open-source Open Network Automation Platform (ONAP) to its Blue Planet network management platform.

Operators want to use automation to help tackle the growing complexity and cost of operating their networks.

Kevin Wade“Policy plays a key role in this goal by enabling the creation and administration of rules that automatically modify the network’s behaviour,” says Kevin Wade, senior director of solutions, Ciena’s Blue Planet. 

Incorporating ONAP code to enhance Blue Planet’s policy engine also advances Ciena’s own vision of the adaptive network.
