It's not the space that is the defining metric. It is what can be done in that space. With CAPEX at 10% of existing processes and no requirement for multiple work stations where all those little feet cluster about. It is a fabrication line that that can produce roughly 476 optical engines per wafer at high throughput.
What is not to like about that? Production wil be dictated by demand and I think demand is going to be very high and production will ramp accordingly.
