COBO acts to bring optics closer to the chip 

The formation of the Consortium for On-Board Optics (COBO) highlights how, despite engineers putting high-speed optics into smaller and smaller pluggable modules, further progress in interface compactness is needed.

The goal of COBO, announced at the OFC 2015 show and backed by such companies as Microsoft, Cisco Systems, Finisar and Intel, is to develop a technology roadmap and common specifications for on-board optics to ensure interoperability.

“The Microsoft initiative is looking at the next wave of innovation as it relates to bringing optics closer to the CPU,” says Saeid Aramideh, co-founder and chief marketing and sales officer for start-up Ranovus, one of the founding members of COBO. “There are tremendous benefits for such an architecture in terms of reducing power dissipation and increasing the front panel density.”

OFC 2014 product round-up - Final part

Part 2: Client-side technologies

The industry is moving at a clip to fill the void in 100 Gig IEEE standards for 100m to 2km links. Until now, the IEEE 10km 100GBASE-LR4 and the 10x10 MSA have been the interfaces used to address such spans.

But responding to data centre operators, optical players are busy developing less costly, mid-reach MSAs, as was evident at the OFC exhibition and conference, held in San Francisco in March. 

Meanwhile, existing IEEE 100 Gigabit standards are skipping to the most compact CFP4 and QSFP28 form factors. The -LR4 standard was first announced in a CFP in 2010, and moved to the CFP2, half the size of the CFP, in 2013. Now, several companies have detailed CFP4 -LR4 products, while Source Photonics has gone one better, announcing the standard in a QSFP28.

OFC 2014 industry reflections - Part 2

Ciena and Ovum comment on the noteworthy developments and trends following the recent OFC 2014 exhibition and conference. 


The high cost of 100 Gigabit Ethernet client modules has been a major disappointment to me as it has slowed adoption
