That’s a misconception:
$SIVE is the laser supplier for next gen architectures, not just CPO scale up.
Pluggable, scale out CPO, scale up CPO, NPO, etc.
- Sivers and $JBL went god-mode and developed 1.6T optical transceivers with CW lasers.
Effectively designing around the EML bottlenecks, and even made things more power efficient.
From quotes from Jabil management they created a “relatively dramatic moat”.
So for the next gen of 1.6T pluggable transceivers, Sivers seems immediately used.
Markets missed this nuance too: after Jabil’s announcement, other pluggable players reached out, and SIVE is working with them now (prob codevelopment, qualification stage).
There’s not too many players that build optical transceivers that aren’t vertically integrated like Lumentum (think: Innolight/eoptolink, and maybe others).
So these are active developments, just not public material yet and could be a new press release anytime.
- for CPO scale out which happens H2 2026 onward like $POET, $SIVE is a laser supplier for those players.
- scale up CPO is h2 2027, from Ayar and Nvidia’a NVLink CPO ecosystem and that’s the main volume ramp across optical players.
But this is where $SIVE looks like they mog every other player from supply chain mapping.
Since they’ve likely been working + designed in with $MRVL Celestial, Lightmatter, Lightelligence and the others since they were small way back when.
On top of things like this:
For foundries like $GFS, $SIVE is the reference laser.
Not even including massive companies like O-Net building ELS with $SIVE, likely for the Asian hyperscalers supply chains.
This is why $SIVE is by far my favorite laser chokepoint long.
Feels like they’re everywhere in new optical architectures starting beginning of 2027.

股神,Sivers的DFB激光阵列因为是波分复用,又是多通道,算下来速率好高,只在scale-up才用得上吧? 会不会大规模量产要很久很久?中间可能有各种风险。
Another one of @aleabitoreddit tracked stocks.
$AAOI
The bears are fighting the last cycle. Calling it a "meme stock".
Actually it's becoming scarce US optical capacity for AI clusters.
800G ramp.
1.6T order.
Hyperscaler pull.
In-house lasers.
Houston capacity buildout.
Optical capacity is the AI bottleneck, so $AAOI has no business being analyzed like a normal component cyclical.
$SIVE $XFAB
One of @aleabitoreddit most mentioned tickers $SIVE is still one of my favorite setups.
It’s laser arrays going into GF silicon photonics reference designs for CPO/LPO/optical engines.
If CW lasers become the scarce thing after $NVDA locked big capacity, Sivers is exactly the type of independent Western supply that gets strategic af.
$ALRIB is a tiny pick-and-shovel for AI/quantum photonics.
ROSIE is about putting BTO/STO functional oxides onto 300mm silicon wafers, exactly the kind of equipment layer that matters when silicon photonics scales. A second ROSIE system is expected for a leading U.S. quantum player, with production-system work by year-end.
This is tracked by Serenity like $SIVE and $AAOI.
