On slide 5 of the reference it says “ Note: 50GE cases taken for simplicity, applies to 100GE as well” It isn’t clear to me how this applies to 100G as the legacy system would be 100G. I think an equivalent slide showing what 100G would look like (maybe including
discussion of module form factors) would be helpful. Mike Dudek

Hi Brad, We tried to capture the details of the various applications in Rob’s presentation: http://www.ieee802.org/3/50G/public/adhoc/archive/stone_021716_50GE_NGOATH_adhoc-v2.pdf We will have an updated presentation in Macau.
More broadly, you raise a very important question which is the relevance of IEEE 802.3 broad market potential, economic feasibility, and distinct identity criteria
to the realities of the market place today. The trend has been for exponential proliferation of optical PMDs and form factors. At 10G the industry consensus was that lowest cost is achieved by reaching agreement on a couple of solutions (SR and LR in SFP+)
which everyone focused on developing and deploying, hence creating a broad market. For 100G and higher, the new industry approach to lowest cost is developing unique technology optimized to individual applications. MS nicely articulated this perspective in
802.3 by commenting that it will deploy whatever best solves its problems, independent of whether it’s standardized in the IEEE or not. Other Web 2.0 companies have similar approach. Since different end users have different requirements, the industry has responded
by developing multitude of different solutions. Which raises the question whether there will even be such a thing as a broad market in the optics industry, and if not then it’s problematic to use it as a criteria for new standards. Chris From: B Booth [mailto:bbooth@xxxxxxxx]
If we're going to use titles like "Supported Applications" can we at least highlight what those applications are. Where in the network is that link
intended to be used? What is the intended application space or market? From:
Wangxinyuan (Xinyuan) Another option?
Just borrow from Chris table, with “S3”.

The 50/100/200G SG will be making a choice in Macau between two objective setting scenarios for 50, 100, 200Gb/s xAUI chip-to-module
interfaces. [The entire original message is not included.]
