The CEO of Alcatel-Lucent, Michel Combes, has brushed off rumours of a tie-up with Nokia, after reports surfaced last week that Nokia's board was considering the move as a strategy option.

"You will have to ask Nokia," said Combes. "I'm fully focussed on the Shift Plan, it is the right plan [for the company]; I don't want to be distracted by anything else."

Combes was speaking at the opening of Alcatel-Lucent's cloud R&D centre in Kfar Saba, Israel, where the company's internal start-up CloudBand is developing cloud technology for carriers.

Ranovus developing DWDM links for the data centre

Ranovus has raised US $11 million in funding to develop Terabit capacity links for the data centre. The Ottawa-based start-up plans to use dense wavelength-division multiplexing (DWDM) technology to create huge data pipes that reduce significantly the power consumption, and cost, per bit.

OIF demonstrates its 25 Gig interfaces are ready for use

Eleven companies have been participating in nine demonstrations at the European Conference and Exhibition on Optical Communication (ECOC2013) being held in London this week.

The Open Internetworking Forum (OIF) has demonstrated its specified 25 and 28 Gigabit-per-second (Gbps) electrical interfaces working across various vendors' 100 Gigabit modules and ICs.

"The infrastructure over the backplane is maturing to the point of 25 Gig; you don't need special optical backplanes" John Monson, Mosys

"The ecosystem is maturing," says John Monson, vice president of marketing at Mosys, one of the 11 firms participating in the demonstrations. "The demos are not just showing the electrical OIF interfaces but their functioning between multiple vendors, with optical standards running across them at 100 Gig."

The demonstrations - using the CFP2, QSFP and CPAK optical modules and the 28Gbps CEI-28G-VSR module-to-chip electrical interface - set the stage for higher density 400 and 800 Gigabit line cards, says Monson. The CEI-28G-VSR is specified for up to 10dB of signal loss, equating to some 4 to 6 inches of trace on a high-quality material printed circuit board.

Q&A with Jerry Rawls - Part 2 

The concluding part of the interview with Finisar's executive chairman and company co-founder, Jerry Rawls, to mark the company's 25th anniversary.

Second and final part

 

Guys that are in the silicon photonics industry have a religion. It does not make any difference what the real economics are, what the real performance is, they talk with a religious fervour about what might be possible with silicon
