Suresh said; "we remain very optimistic about our advancement of POET’s product roadmap throughout 2021.”

I would like to add from the article below WRT any possible laser delays :

As part of the joint venture, POET will supply optical interposers, manufactured by semiconductor wafer fab partner, SilTerra, at its 8 inch foundry in Kulim, Malaysia. Meanwhile Sanan IC will provide lasers, photodetectors and other active devices, which will then be integrated into the optical interposers at the joint venture's facility in Xiamen, to form optical engines.

Therefore since Sanan is supplying the lasers, I would think allsystems should be a go as far as the JV is concerned
