ECOC 2015: Reflections

Gazettabyte asked industry executives what trends and highlights they noted at the recent European Conference on Optical Communication (ECOC) event, held in Valencia. Here are three views.

ECOC was a big show and included a number of satellite events, such as the 6^th European Forum on Photonic Integration, the 3^rd Optical Interconnect in Data Center Symposium and Market Focus, all of which I attended. So, lots of information to digest. 

My focus was mainly on data centre optical interconnects and photonic integration.

Silicon photonics: "The excitement has gone"

The opinion of industry analysts regarding silicon photonics is mixed at best. More silicon photonics products are shipping but challenges remain.

Part 1: An analyst perspective

"The excitement has gone,” says Vladimir Kozlov, CEO of LightCounting Market Research. “Now it is the long hard work to deliver products.” 

Dale Murray, LightCounting

However, he is less concerned about recent setbacks and slippages for companies such as Intel that are developing silicon photonics products. This is to be expected, he says, as happens with all emerging technologies.

Mark Lutkowitz, principal at consultancy fibeReality, is more circumspect. “As a general rule, the more that reality sets in, the less impressive silicon photonics gets to be,” he says. “The physics is just hard; light is not naturally inclined to work on the silicon the way electronics does.”

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.

Compass-EOS raises $42M

Compass-EOS has raised $42 million in investment. The Israeli start-up launched its r10004 IP core router in March and has so far announced two customers: NTT Communications and the China Education and Research Network, CERNET. The company says it has a second tier-one operator yet to be announced.

"Both global operators have purchased routers on several occasions for several types of deployments," says Asaf Somekh, vice president of marketing at Compass-EOS. “There are also a couple more smaller operators that we cannot disclose at this stage." The company is  involved in several trials in the US, Japan and EMEA.
