1.6T optical order chain
Break 800G to 1.6T order transmission into modules, lasers, DSPs, and materials.
A Reviewable Logic Chain
Each card stays open and maps one transmission node without collapsible controls or pseudo-precise scores.
Hyperscaler
MRVL leans chip and ASIC certainty; COHR leans photonics manufacturing and order delivery.
COHR / LITE
If 1.6T stays at the demo layer, material and second-order names should receive a valuation discount.
MRVL / MXL
Post-earnings, watch for language shifting from sampling to volume or multi-customer production.
AXTI
MRVL leans chip and ASIC certainty; COHR leans photonics manufacturing and order delivery.
Core question
The key question for 1.6T is not whether demos are exciting, but whether the chain has moved from sampling to repeatable volume logic.
This report tests whether the buyer-module-DSP-material chain is coherent enough to treat 1.6T as execution evidence, not just narrative.
Chain logic
Layer 1: Check hyperscaler disclosures for moves from sampling language to design-in commitments, especially within datacenter communications.
Layer 2: Validate COHR/Lite module positioning through customer breadth, not isolated project updates.
Layer 3: Validate MRVL/MXL progress through productization pace and whether product pricing reflects less optionality.
Conclusion
The current chain is a mix of narrative clarity and execution uncertainty. Visibility exists, but closure is uneven across layers.
For valuation, the hinge is language progression. If the chain remains in project/demo language, 1.6T beta in higher layers should be priced with a haircut.
Next checks
Priority checks are datacenter mix stability at COHR, design and pricing quality at MRVL, and whether AXTI can align InP demand visibility with permit and capacity information.

- Order wording, Q4/FY2027 guidance, datacenter communications mix
- Current read
- Demand is strong, but high prices need earnings to clear order expectations.
- Next question
- Is 1.6T moving from demos into multi-customer volume?
MRVL leans chip and ASIC certainty; COHR leans photonics manufacturing and order delivery.
If 1.6T stays at the demo layer, material and second-order names should receive a valuation discount.
Post-earnings, watch for language shifting from sampling to volume or multi-customer production.
