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.
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.
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.
Rating Watch. The world's number-one leader in high-speed AI optical modules, with 2025 net profit attributable to shareholders of 10.797 billion yuan and a durable moat. But at roughly 1,037 yuan the current price already sits above the 700-950 yuan upper bound of an optimistic intrinsic value, at about 77x PE, leaving no margin of safety. Rating Watch: a superb business priced for a decade of optimistic growth, not a purchase with downside protection.
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.
