I think if you refer to Slide 28 from the May 2016 Poet Presentation you will see we are on schedule introducing this product as part of the "Long Reach Communications" Laser & Transceiver Product Development Roadmap.

Slide 19 shows the "Short Reach Communications" - Transceiver Product Development Roadmap, which indicates the Detector & TIA should be introduced before the end of the year.
