Companies coming from an optical background typically are less familiar with complex modulation schemes such as PAM, and may consider it less technical viable. The group also takes costs and broad market adoption into consideration.
Ironically, Intel Corp. has not made any presentations to the group despite making a big splash recently by sampling 4x25G silicon photonics products based on a decade of research. It has only sent one engineer to the meetings so far, and that person did not attend on more than half of the meeting days.
Cisco is working on silicon photonics using 2.5-D chip stacks, said the head of Cisco’s transceiver group, speaking at DesignCon. Startups Kotura and Luxtra shared their plans separately to field 4x25G silicon photonics in 2014.
All four players hope to drive down 100G costs for a range of switches and other products. The meetings have drawn participants from a broad range of service, system and component vendors including Alcatel-Lucent, Deutsche Telekom, HP, Juniper, Microsoft and a range of startups.
"The entire industry is investing to bring the cost of optics down, and when that happens we can get to products with multiple 100G ports," said Siddharth Sheth, vice president of marketing at Inphi Corp., speaking on a panel at the Linley Group event here this week.
in terms of WDM, it nicely lends itself to PCI Express protocol- where lanes are bonded together (from x2 to x16)to increase port speed. WDM makes repurposing simple for transceiver makers. And since PCIe is inherently a short reach technology, would only complement the Ethernet space.
Would seem like a 'win-win-win' to me! :-)
Nice article Rick. I should mention that the bullet items separating proposals out by company were not provided by me, but probably gleaned from the IEEE P802.3bm website.
Within the IEEE, participation is by individual and not by company. I did not, nor would I characterize proposals by company name.
Standards are good for commerce and the consumer, at a high level. However, if creating standards limits the R&D options for the relatively few major players spending billions on Si Photonics, then this could be counter-productive in the near term. Is it too early to be locking things down in 100 Gb/s standards?
This viz was created before one of the GOP debates to see which of the potential candidates had a better job creation record.-"Peter F. Spittler":http://presentationsolutions.org/2012/11/01/phil-melugin/
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
