Sunday, September 29, 2013 at 5:30PM 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.
Wednesday, September 25, 2013 at 1:52PM 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.

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
Thursday, September 12, 2013 at 9:03AM Intel and Corning have further detailed their 1.6 Terabit interface technology for the data centre.
The collaboration combines Intel's silicon photonics technology operating at 25 Gigabit-per-fibre with Corning's ClearCurve LX multimode fibre and latest MXC connector.

Tuesday, September 10, 2013 at 9:52AM Coriant's CTO, Uwe Fischer, explains its Intelligent Optical Control and how the system will complement Transport SDN.
"You either master all that complexity at once, or you find the right entry point and provide value for each concrete challenge, and extend step-by-step from there"
