2026-07-17T15:27:41+00:00@johnoao CPO hasn’t scaled up yet. Lot of their earnings come from 2028 TAM for FAU. There’s just a lot of uncertainty recently due to CPO delay reports and $GLW glass bridge. https://t.co/8kyWZ2x0Mw · 102 likes · 31,041 views
2026-07-13T00:45:13Just a semi recap TLDR: - $GLW glass bridge per Morgan Stanley has potential, but hard to displace FAU (like FOCI) in short term - $SPCX Starlink Gen 3 is scaling to 100,000 units (10x prev gen) creating possible capacity constraints for suppliers of switches to CCL. - PCB supply shortages are pr… · 2042 likes · 666,769 views

2026-04-21People nonstop ask me about $LPKK / $LPK for my opinion Yes, I mentioned they're like a chokepoint for glass core substrates for LIDE (laser induced deep etching) way back when.

2026-03-25@AtlasShrug1 The supply chain map is just very interesting. When a follower found likely $LITE OCS upstream suppliers on the glass wafer level alongside hundred billion dollar companies like $GLW. Not recommending it and never said it was a good investment. · 14 likes · 7,338 views
2026-03-25So just checked out the comments... $P4O does look like a potential upstream $LITE supplier at a $34M MC. How it likely maps: -> Plan Optik $P4O (Glass Wafers) -> Teledyne $TDY or Silek (Mem Foundries) -> $LITE (OCS Switches) -> $GOOGL (TPUs) However, $LITE likely dual sources with Corning ( … · 314 likes · 213,905 views
