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.

Interview: Finisar’s CEO reflects on a notable year

Michael Hurlston has had an eventful 2018. 

The year started with him replacing Finisar’s veteran CEO, Jerry Rawls, and it is now ending with Finisar being acquired by the firm II-VI for $3.2 billion.

Michael Hurlston

Finisar is Hurlston’s first experience in the optical component industry, having spent his career in semiconductors. One year in and he already has strong views about the industry and its direction.

“We have seen in the semiconductor industry a period of massive consolidation in the last three to four years,” says Hurlston, in his first interview sinced the deal was announced. “I think it is not that different in optics: scales matters.”    

Hurlston says that, right from the start, he recognised the need to drive industry consolidation. “We had started thinking about that fairly deeply at the time the Lumentum-Oclaro acquisition was announced and that gave us more impetus to look at this,” says Hurlston. The result was revealed in November with the announced acquisition of Finisar by II-VI.

Books in 2018 - Part 2

Some more books consumed in 2018, as recommended by Maxim Kuschnerov and Andrew Schmitt.

It is hard to believe the book Fire and Fury: Inside the Trump White House by Michael Wolff was published in 2018. Judging by what has happened since Trump’s inauguration, this recollection of his first days in the White House seems outdated. But it was fun to read while the memory of the election was still fresh. It is hard to judge whether all the book’s sources are truthful but the main message is certainly not too far off.

Valery Tolstikhin, president and CEO of Intengent, a consultancy

I read too many technical and business texts during the day so I leave my bedtime for more human reading.  

This year I wasn’t too lucky with fiction books but I did read some great non-fiction ones: Homo Deus: A Brief History of Tomorrow by Yuval Noah Harari, Jordan Peterson’s 12 Rules for Life: An Antidote to Chaos and Leonardo Da Vinci by Walter Isaacson.

Relentless traffic growth leads to a ROADM rethink

Technology briefing: ROADMs

Lumentum has developed an optical switch to enable reconfigurable optical add-drop multiplexers (ROADMs) to cope with the traffic growth expected over the next decade. 

The company’s MxN wavelength-selective switch (WSS) will replace the existing multicast switch used in colourless, directionless and contentionless ROADMs. The Lumentum TrueFlex 8x24 twin switch will enable networking nodes of 400-terabit capacity.

“This second-generation switch is what will take us into the 100 gigabaud and super-channel era of network scalability,” says Brandon Collings, CTO of Lumentum.

Habana Labs unveils its AI processor plans

Start-up Habana Labs has developed a chip architecture that promises to speed up the execution of machine-learning tasks. 

The Israeli start-up came out of secrecy in September to announce two artificial intelligence (AI) processor chips. One, dubbed Gaudi, is designed to tackle the training of large-scale neural networks. The chip will be available in 2019. 

Eitan MedinaGoya, the start-up’s second device, is an inference processor that implements the optimised, trained neural network.

The Goya chip is already in prospective customers’ labs undergoing evaluation, says Eitan Medina, Habana’s chief business officer.

Habana has just raised $75 million in a second round of funding, led by Intel Capital. Overall, the start-up has raised a total of $120 million in funding.
