800G Optical Transceiver Module (SFP/OSFP/QSFP-DD) — transceiver

Opportunity: NVIDIA's H100/H200 GPU fabric is consuming 800G SFP/OSFP optics at huge volume; the duopoly of Innolight + Eoptolink and Lumentum's $750M Cloud Light bet validate that this is the current cash-printing SKU of the AI buildout.

800G pluggable transceiver is the current product — concrete A5 customer-win evidence shows two Chinese vendors lock ~60% of NVIDIA's 800G supply with Lumentum chasing via Cloud Light. Risk is generational: the same evidence pool already signals 1.6T and CPO are next, so the moat is short.

Co-Packaged Optics (CPO) Switch — switch

Opportunity: AI bandwidth wall: pluggable optics power/density can't keep up with GPU scale-out, so hyperscalers want optics co-packaged with the switch ASIC (fact 36cca98b, fact 0ebc4a28 Broadcom Tomahawk 6 Davisson 102.4T CPO shipping).

CPO switches are the single biggest '' signal in this topic — Broadcom is shipping Tomahawk 6 Davisson at 102.4T with CPO, NVIDIA has publicly endorsed CPO for GPU fabrics, and Astera Labs is actively hiring optical validation + advanced packaging talent flagged with 'cpo'. What's missing: independent A4/A5 customer-win evidence outside Broadcom's announcement; the 'third time' framing implies execution risk.

Silicon Photonics Engine (data center) — silicon photonics PIC

Opportunity: Silicon photonics is being positioned as the enabling layer for both CPO and high-density pluggables; the tension between TSMC's empire-building and Jensen's 'stay on copper' quote is exactly the kind of contested narrative that signals an inflection.

Silicon photonics is the contested foundation layer — Astera is hiring optical validation with explicit silicon_photonics specialty and TSMC is building capacity, but the lead AI customer (NVIDIA CEO) is publicly hedging the timeline. Position: with binary timing risk.

1.6T Optical Transceiver Module — transceiver

Opportunity: 1.6T is the explicit next-generation upgrade target on every cluster roadmap; InP supply (DFB/EML lasers) is being called out as the upstream chokepoint, framing it as both a product opportunity and a supply-chain bottleneck investors care about.

1.6T is a clear — strong A2 demand chatter and explicit chokepoint framing (InP / 200G/lane SerDes) make it the obvious successor to 800G. Missing direct A5 customer-win evidence: nobody in the dataset is yet declared the volume-supply winner for 1.6T to NVIDIA.
