Hi Dennis, I don't have a great understanding of the requirements for qualification but the laser requires the longest testing. The POET platform is very versatile with the capacity to use multiple types of lasers depending on the application requirements and what the customers are requesting. Ultimately it is up to the customer and I expect many would place a significant number of the finished products (pluggable modules) into service for real world testing and would gradually ramp the numbers as they become satisfied with the performance and reliability.

For example the POET platform can use external cavity lasers or gain chips for optical transmission which are typically lower cost to build and take less power to operate than the more expensive and more commonly used alternative of Distributed Feedback Lasers (DFB) lasers. Such lasers require an expensive process of writing gratings and regrowth of epitaxial layers in the manufacturing process. Gain chips also provide greater reliability and longer life to optical systems relative to Distributed Feedback Lasers (DFBs).
