Hey Dan, 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! :-)

Excellent point! What ever happened to competing technologies being vetted by the marketplace?

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?

I attended few IEEE standard meetings and it was always like this...everyone was trying to position their technology as the best and co-opt as many others as possible...business as usual

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/

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
