Until POET finally says "here it is" and it's the better mouse trap, many others will be working towards some form of an "integration solution", because it's the way forward.
As Suresh once said, basically, "if we are the only one's trying this, it would probably mean we were going the wrong way".
All the information we have to date still indicates that POET's solution is the most cost effective, no lenses, no mirrors, no glass block and no GOLD box.
For POET, we now need the assembled transciever to be qualified and into production with our customer and then the rest of the industry will take a look.
