Imec gears up for the Internet of Things economy

Luc Van den hove is talking in the darkened ballroom in a hotel next to the brilliantly sunlit marina in Herzliya.

It is the imec's CEO's first trip to Israel and around us the room is being prepared for an afternoon of presentations the Belgium nanoelectronics research centre will give on its work in such areas as the Internet of Things and 5G wireless to an audience of Israeli start-ups and entrepreneurs.

Luc Van den hoveImec announced in February its plan to merge with iMinds, a Belgium research centre specialising in systems software and security, a move that will add 1,000 staff to imec's 2,500 researchers.

At first glance, the world-renown semiconductor process technology R&D centre joining forces with a systems house is a surprising move. But for Van den hove, it is a natural development as the company continues to grow from its technology origins to include systems-based research.

OIF document aims to spur line-side innovation

The Optical Internetworking Forum (OIF) has completed defining the CFP2-ACO (analogue coherent optics) module, used for coherent-based optical transmission. The industry body's CFP2-ACO Implementation Agreement document has been developed to help optical component vendors bring innovative line-side products to market more quickly.

The pluggable CFP2-ACO houses the coherent optics, known as the analogue front end. The components include the tuneable lasers, modulation, coherent receiver, and the associated electronics - the drivers and the trans-impedance amplifier. The Implementation Agreement also includes the CFP2-ACO's high-speed electrical interface connecting the optics to the coherent DSP chip that sits on the line card.

Start-up Sicoya targets chip-to-chip interfaces

Sicoya has developed a tiny silicon photonics modulator which it is using to design chip-to-chip optical interfaces. The German start-up believes such optical chips - what it calls application-specific photonic integrated circuits or ASPICs - will be needed in the data centre, first for servers and then switches and routers.

“The trend we are seeing is the optics moving very close to the processor,” says Sven Otte, Sicoya’s CEO.

Sicoya was founded last year and raised €3.5 million ($3.9 million) towards the end of 2015. Many of the company’s dozen staff previously worked at the Technical University of Berlin. Sicoya expects to grow the company’s staff to 20 by the year end.

Ciena shops for photonic technology for line-side edge

Briefing: DWDM developments

Part 3: Acquisitions and silicon photonics

Ciena is to acquire the high-speed photonics components division of Teraxion for $32 million. The deal includes 35 employees and Teraxion’s indium phosphide and silicon photonics technologies. The systems vendor is making the acquisition to benefit its coherent-based packet-optical transmission systems in metro and long-haul networks.

Sterling Perrin

“Historically Ciena has been a step ahead of others in introducing new coherent capabilities to the market,” says Ron Kline, principal analyst, intelligent networks at market research company, Ovum. “The technology is critical to own if they want to maintain their edge.”

“Bringing in-house not everything, just piece parts, are becoming differentiators,” says Sterling Perrin, senior analyst at Heavy Reading.    

Ciena designs its own WaveLogic coherent DSP-ASICs but buys its optical components. Having its own photonics design team with expertise in indium-phosphide and silicon photonics will allow Ciena to develop complete line-side systems, optimising the photonics and electronics to benefit system performance.

Next-generation coherent adds sub-carriers to capabilities

Briefing: DWDM developments

Part 2: Infinera's coherent toolkit 

Source: Infinera

Infinera has detailed coherent technology enhancements implemented using its latest-generation optical transmission technology. The system vendor is still to launch its newest  photonic integrated circuit (PIC) and FlexCoherent DSP-ASIC but has detailed features the CMOS and indium phosphide ICs support.

The techniques highlight the increasing sophistication of coherent technology and an ever tighter coupling between electronics and photonics.

BT makes plans for continued traffic growth in its core

Briefing: DWDM developments

Part 1

Kevin Smith: “A lot of the work we are doing with the trials have demonstrated we can scale our networks gracefully rather than there being a brick wall of a problem.”

BT is confident that its core network will accommodate the expected IP traffic growth over the next decade. Traffic in BT’s core is growing at between 35 and 40 percent annually, compared to the global average growth rate of 20 to 30 percent. BT attributes its higher growth to the rollout of fibre-based broadband across the UK.

The telco is deploying 100-gigabit wavelengths in high-traffic areas of its network. “These are key sites where we're running out of wavelengths such that we need to implement higher-speed ones,” says Kevin Smith, research leader for BT’s transport networks. The operator is now trialling 200-gigabit wavelengths using polarisation multiplexing, 16-quadrature amplitude modulation (PM-16QAM).

MultiPhy raises $17M to develop 100G serial interfaces

Start-up MultiPhy has raised U.S. $17 million to develop 100-gigabit single-wavelength technology for the data centre. Semtech has announced it is one of the companies backing the Israeli fabless start-up, the rest coming from venture capitalists and at least one other company.

MultiPhy is developing chips to support serial 100-gigabit-per-second transmission using 25-gigabit optical components. The design will enable short reach links within the data centre and up to 80km point-to-point links for data centre interconnect.

“It is not the same chip [for the two applications] but the same technology core,” says Avi Shabtai, the CEO of MultiPhy. The funding will be used to bring products to market as well as expand the company’s marketing arm.
