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.

OFC/NFOEC 2013 industry reflections - Part 4

Gazettabyte asked industry figures for their views after attending the recent OFC/NFOEC show. 

 

"Spatial domain multiplexing has been a hot topic in R&D labs. However, at this year's OFC we found that incumbent and emerging carriers do not have a near-term need for this technology. Those working on spatial domain multiplexing development should adjust their efforts to align with end-users' needs"

T.J. Xia, Verizon

OFC/NFOEC 2013 industry reflections - Part 2

Gazettabyte asked industry figures for their views after attending the recent OFC/NFOEC show held in Anaheim. Part 2

 

Bill Gartner, vice president and general manager of high-end routing and optical business unit at Cisco Systems.

There were several key themes during this year’s OFC conference, but what I found most compelling were the disruptive trends and technologies that stand to significantly impact the optical communications market in the coming years.

 

"SDN could be the single biggest disruptor in the transport industry and has the potential to transform network programmability and orchestration"
