Bull points
- OFC is the premier optical networking and communication conference. And this year, there was a notable emphasis on the massive build-out of data centers for AI. Data center CapEx investments continue to surge.
- Encouragingly, the industry is thinking long-term. They are taking measures to address near-term needs while also anticipating massive future growth opportunities.
- The growing demand for 200G per lane transceivers and the transition to 400G per lane provide opportunities for Aluma's high-speed in-gas photodiodes.
Bear points
- First, adding fab capacity may require several years. Second, although efforts are being made to transition to 6-inch indium phosphide, many claim this won't provide sufficient supply to meet market demand. And last, there is a major shortage of indium phosphide substrates of all sizes. Suppliers are sold out for years, with only limited increase in capacity expected in the near term, and geopolitics adding a degree of uncertainty.
- We described the wealth of activity across AI Datacom, mobile and consumer, and defense and aerospace. There is also a noticeable uptick in engagements from prospective Quantum customers.
- We've always said that eventually we might be fabless or very fab-lite that if an opportunity comes that requires multiple of the MOCBD tools that we have, we're probably not going to make that capex investment ourselves.
