Potential Restrictions Positive for the U.S. Optical Communications Supply Chain, with COHR Possibly the Clearest Beneficiary
If the U.S. restricts approvals for new Chinese data center optical transceivers and related components, non-Chinese suppliers would benefit, but insufficient capacity, qualification cycles, and dependence on InP substrates mean large-scale substitution is difficult in the near term.
- The relevant restrictions have not yet been formally released and are more likely to target future product approvals rather than already installed equipment.
- Innolight and Eoptolink together account for about 50% of the optical transceiver market, and potential restrictions could release substantial substitution demand.
- COHR is viewed as the clearest beneficiary due to its scale and vertical integration capabilities; AAOI and FN may also capture incremental demand.
- LITE has relatively low direct transceiver exposure, but tight EML supply may persist, creating an indirect benefit.
- Non-Chinese manufacturers currently lack sufficient capacity to fully meet AI capex demand, clearly constraining near-term share switching.
- Chinese InP substrate supply may become a key bottleneck for capacity expansion by U.S. manufacturers.
Report interpretation
Overview
The report assesses market rumors that the U.S. government and the Federal Communications Commission may restrict Chinese data center components, especially optical transceivers. Since there are no formal rules yet, the scope of restrictions, implementation method, and applicability to non-Chinese branded products containing Chinese components remain unclear. The report believes the event is broadly positive for U.S. and other non-Chinese optical communications suppliers, but supply capacity and customer qualification speed will determine the actual pace of benefits.
Core views
Potential policy would reinforce supply chain diversification among U.S. cloud providers and prolong tight supply-demand conditions for optical communications products. COHR has relatively the strongest certainty of benefit due to its scaled capabilities and high degree of vertical integration; AAOI and FN have the potential to capture some incremental demand. LITE mainly benefits indirectly through continued tight EML supply-demand, but its dependence on Chinese InP substrates is an offset. CIEN has limited direct competitiveness in the data center market, while GLW has limited upside because existing Chinese optical fiber penetration in U.S. data centers is low.
Analysis framework
The report uses policy-event scenario analysis and combines supplier market share, vertical integration capability, non-China capacity, customer qualification progress, and dependence on key raw materials to make relative comparisons of potential share shifts and industry chain impacts.
Methodology notes
Assess the impact of potential regulatory measures on future product access and supplier share
Distinguishes media reports from formal rules and focuses on judging whether restrictions may cover future product approvals or existing equipment, while also considering that the scope of rule applicability remains unclear.
Judge substitution speed based on capacity, qualification cycles, and key material supply
Even if policy creates substitution demand, non-Chinese manufacturers still need sufficient capacity, completion of cloud customer qualification, and assured supply of key inputs such as InP substrates.
Compare the strength of company benefits based on scale, product exposure, and degree of vertical integration
COHR is listed as the clearest scaled beneficiary, AAOI and FN may capture incremental demand, LITE mainly benefits indirectly, while CIEN and GLW have more limited potential upside.

- LITEUpstream indirect beneficiary
- Strengths
- A reduced likelihood that Chinese suppliers alleviate supply tightness helps prolong tight EML supply conditions.
- Weaknesses
- Direct optical transceiver exposure is relatively low.
- Comparison
- Compared with COHR, its benefits come more from upstream laser supply-demand rather than directly replacing Chinese transceiver share.
- Risks
- Chinese restrictions on InP substrates may weaken its supply and capacity expansion capabilities.
- CIENLimited potential upside
- Strengths
- Has attempted to qualify more diversified suppliers.
- Weaknesses
- Lacks direct competitive exposure in the data center optical transceiver field.
- Comparison
- Compared with COHR, AAOI, and FN, the direct benefits from the policy are smaller.
- Risks
- Supply chain adjustment costs rise without obtaining corresponding market share.
- GLWLimited potential upside
- Strengths
- Existing optical fiber business foundation in U.S. data centers is relatively solid.
- Weaknesses
- U.S. data centers originally used relatively little Chinese optical fiber, leaving limited substitution room.
- Comparison
- Benefit elasticity is lower than companies directly involved in optical transceivers and lasers.
- Risks
- The market overestimates the actual boost from policy to optical fiber demand and share.

Impact & implications
If restrictions are implemented, the bargaining power and order visibility of the U.S. optical communications industry chain may improve, and the duration of tight supply may be extended, but the policy does not necessarily lead to immediate and complete domestic substitution. Investment judgments should focus on distinguishing direct transceiver exposure from upstream laser and materials exposure, while monitoring customer qualification and capacity expansion capabilities. The policy may also be resolved through negotiations, such as encouraging Chinese cloud providers to purchase U.S. components, so the final impact depends on rule details and subsequent arrangements by both China and the United States.
Risks
- The U.S. government and the Federal Communications Commission have not yet issued formal rules, and the policy may not be implemented, may be delayed, or may have a significantly narrowed scope.
- Non-Chinese manufacturers' current supply capacity is insufficient to fully meet AI capex demand, which may create delivery bottlenecks or pricing pressure.
- Customer qualification cycles for optical modules and components are relatively long, limiting the speed of near-term market share shifts.
- It remains unclear whether restrictions will cover non-Chinese branded modules containing Chinese components.
- U.S. suppliers depend on InP substrates from China, and potential retaliation may weaken their capacity expansion capabilities.
- U.S.-China negotiations may create alternative solutions, reducing the degree of benefit that unilateral restrictions provide to U.S. suppliers.
- Morgan Stanley has shareholding, investment banking, or other service relationships with some covered companies, and investors should make prudent judgments together with the disclosures.
What to watch
- Whether the White House and the Federal Communications Commission issue formal rules and the specific effective date.
- Whether the rules target future product approvals or also affect already installed equipment.
- Whether optical modules from non-Chinese brands but containing Chinese components are included in the restrictions.
- Capacity expansion progress, order changes, and cloud customer qualification status for COHR, AAOI, and FN.
- The stability of InP substrate procurement by LITE and COHR and alternative sources.
- Whether U.S. cloud providers accelerate expansion of qualified supplier lists.
- Whether China and the United States form policy alternatives through procurement commitments or other agreements.
