T&S Communications: A Real Upstream Bottleneck, Priced as if Scarcity Economics Were Permanent
T&S Communications is an upstream optical-component supplier whose active optical components, led by 1.6T optical engines, reached 58.1% of revenue in 2025 as revenue grew 58.8% to CNY 5.16 billion with about CNY 2.02 billion of attributable net profit. The business quality is real but so is the concentration: the top five customers were 90.6% of revenue and the largest alone 63.9%. Rating Avoid: at CNY 209.19 and roughly 110 times static earnings, even the report's optimistic scenario of CNY 165 per share sits below the current price.

Yuanjie Semiconductor: Real AI-Optics Growth, Zero Margin of Safety
Yuanjie is an upstream IDM laser-chip maker whose product mix flipped from telecom toward AI-driven data-center silicon-photonics CW light sources, lifting 2025 revenue to CNY 601.4 million (gross margin to 58.15%) and driving 2026 H1 guidance up 339-364% year on year. But the same filings show its largest customer alone supplied 53.35% of 2025 sales (up from 16.38% in 2024), the CNY 1.251 billion phase-two expansion withholds its capacity target, and part of the H1 2026 profit surge is non-recurring fair-value gains. Rating Avoid: at CNY 1,445 the stock already prices in years of flawless scaling above even this report's own optimistic CNY 1,180/share fair-value estimate, with a margin-of-safety verdict of none.

Accelink Technologies: AI Datacom Growth Racing Against a Stretched Valuation
Accelink Technologies is an optical components and optical modules supplier spanning transmission, access, and datacom, with 2025 revenue of CNY 11.929 billion and net profit of only CNY 946 million. The market has already attached a very high-multiple premium for an AI datacom challenger, with an approximately CNY 165.3 billion market value implying about 175x PE, far above leaders such as Zhongji Innolight and Eoptolink that have already converted AI demand into profits. Report rating Avoid: AI datacom growth is real, but the current price has pulled forward too much of the catch-up story.
37/100
Lightelligence Deep Research
Lightelligence is a Hong Kong-listed AI silicon photonics company whose optical interconnect business is stronger than optical computing today. Revenue was only RMB 106 million in 2025, while the company lost RMB 1.342 billion and the HK$569.5 share price leaves no margin of safety. Research rating Avoid: promising technology, but current pricing has pulled forward too much commercialization success.
38/100
Applied Optoelectronics Deep-Dive Research
A high-beta small-cap optical module and optical component name, with data center revenue at 53.9% in 2026Q1 and initial 800G shipments, but also customer concentration, negative cash flow, and ATM-funded growth. The core thesis is that the $158.41 share price already discounts a neutral-to-optimistic scenario and leaves no margin of safety. Research rating Hold: real demand, difficult execution, and an expensive entry point.

Innolight (Zhongji Innolight) : une étude approfondie d'investissement dans la valeur
Notation Surveiller. Leader mondial numéro un des modules optiques haut débit pour l'IA, avec un résultat net part du groupe 2025 de 10.797 milliards de yuans et un fossé concurrentiel durable. Mais à environ 1037 yuans, le cours actuel se situe déjà au-dessus de la borne supérieure de 700-950 yuans d'une valeur intrinsèque optimiste, à environ 77x PE, sans laisser de marge de sécurité. Notation Surveiller : une entreprise superbe dont le prix intègre une décennie de croissance optimiste, non un achat assorti d'une protection à la baisse.

Eoptolink Research from a Long-Term Business Owner's Perspective
Eoptolink is a global leader in high-speed optical modules for 800G and 1.6T AI data-center interconnects. Net profit reached RMB 9.5 billion in 2025 with extremely strong growth, but overseas revenue accounts for 96%, customer concentration is high, cash flow is uneven, and the current RMB 567 share price is far above the upper end of the optimistic intrinsic value range of RMB 320 to RMB 420, leaving no margin of safety. Rating Watch: a high-quality company whose valuation already prices in too much optimism.

Coherent: A Deep-Dive Value Investing Study
Coherent is a vertically integrated photonics manufacturer driven by the twin engines of AI data-center optical interconnect and industrial photonics; in the first nine months of FY2026, Datacenter & Communications made up about 72% of revenue and grew 34% year over year. But customer concentration, inventory rising from $1.438 billion to $2.127 billion, and just $10.06 million of nine-month operating cash flow leave the current price of $353.63, at about 167.6x static earnings, without an adequate margin of safety; rated Watch, with an ideal buy range of $80-120.

Corning In-Depth Value Research Report
Corning is a materials technology platform with real technical moats and direct exposure to AI data-center optical interconnect demand. At $175.83 per share, however, the stock implies roughly 84-94 times earnings and leaves almost no margin of safety. Rating Watch: a high-quality company that deserves close tracking, but not a value buy at today's price.
43/100
Lumentum Holdings: A Deep Value-Investing Study
A photonic-device maker on the critical AI data-center optical-interconnect chain, with a clearly improving fundamental picture but historically volatile cash flow; at roughly $890 per share the stock already prices in years of flawless execution. Rating: Avoid.
Deep Research on the AI Optical Communications Supply Chain
Within AI optical communications, the themes that have already converted into orders and revenue rank, in order, as 800G pluggables, early-stage 1.6T ramp, AI switches and switch chips, EML/CW lasers, and key optical components and high-end optical manufacturing; CPO/NPO/Optical I/O are mid-term architectural directions whose contribution to financials over the next twelve months remains weaker than 800G/1.6T pluggables. Priority names to track are Arista, Cisco, Broadcom, Marvell, Coherent, Lumentum, Fabrinet, Innolight, Eoptolink, T&S Communications, and Accelink. Rating Watch: the demand is real, but the order in which profit is distributed across the chain will keep shifting, so the highest-conviction value sits with switch chips, key lasers, and the system software layer rather than with commoditized module assembly.
