Thank you Rainer. Your explanation is much appreciated. It is obvious that you have invested a significant amount of your time to explain to those of us without experience in this field, in simple terms, just how these transceivers function.

With every technology, there are limitations which affect the cost of ownership. Can you comment on what you believe those limitations would be for the pluggable monolithic transceivers for the data center? I believe most are familiar with the cost issues of the GaAs versus silicon. I believe the ongoing scaling efforts may resolve some of those questions or atleast better define that hurdle for large scale commercialization.

What I am more interested in is the speed limitations if there are any. What I am hearing is that 10 Gb/s is a given and 25 Gb/s and maybe 50 Gb/s could be within reach. I understand that 50 Gb/s transceivers would represent a very large market opportunity for POET over the next several years and the POET's investors would be more than satisfied.

I am trying to understand if that is a limit in terms of speed. Beyond 50 Gb/s would it be necessary to duplicate transceivers rather than continue in increasing speed? Is it possible to extend this technology beyond 50 Gb/s to 100 Gb/s? 500 Gb/s? etc.
