I think there is some confusion here as to what prototype is scheduled for when.

Clearly, from the PIC presentation the  low loss, low cost micro multiplexer and de-multiplexer product for 100G and above transceivers based on the technology developed at its subsidiary BB Photonics Inc. will be first

Engineering samples are expected to be available in the second quarter of 2017 with production commencing in the second half of the year. The technology is well suited for LAN WDM product solutions. The WDM market alone is a billion dollar segment.

They have also stated that an NRE was pushed over to Q1 this year that we will see when finacials are released.

NRE's related to multiplexer and de-multiplexer product for 100G and above transceivers could more than cover financial requirements. We should be in a much better position to make predictions about the company's finances by end Q2 instead of quibling over them now
