According to Technews, the Federal Communications Commission (FCC), the US telecom regulator, is drafting measures to ban imports of new Chinese-made optical transceivers — devices that move data through fiber-optic cables at light speed inside data centers (E1). CNA's report of the same story used near-identical wording, describing the devices' role in data-center fiber transmission (E11).
On timeline, Technews reported that officials hope the ban will be announced and take effect this year, but people familiar with the matter said the restriction could still be modified or shelved (E2). ETtoday, carrying the same CNA wire report, repeated the FCC drafting details (E16). No evidence in this reporting specifies a firm publication date beyond "this year," and no scope details (e.g., which product categories or thresholds) beyond "new" transceivers were disclosed.
The market reaction was immediate. Technews reported that Innolight (中際旭創), the industry's largest shipper, closed down 7.27% on August 5, while Eoptolink (新易盛) fell 5.29% the same day (E3, E4). CNA's report on the story cited the identical figures (E12), as did ETtoday (E17).
| Company | Share price move (Aug 5) | Reported by |
|---|---|---|
| Innolight (中際旭創) | -7.27% | Technews, CNA, ETtoday |
| Eoptolink (新易盛) | -5.29% | Technews, CNA, ETtoday |
The ban targets a market where Chinese suppliers hold leading positions. Citing Counterpoint Research data, Technews reported that Innolight (中際旭創) holds a 27% share of the global data-center transceiver market, the highest of any supplier (E7). CNA cited the same Counterpoint Research figure (E14).
Eoptolink (新易盛) is the second name in the sector: Technews reported it rose to the No. 2 position among global optical module suppliers in 2025, serving as a core 400G and 800G supplier to Amazon and having entered Nvidia's (輝達) supplier base (E10). ETtoday's report carried the same ranking and customer details (E18).
Two structural facts point to why substituting Chinese supply is not straightforward. On the US side, Technews reported that domestic suppliers Coherent (高意) and Lumentum (朗美通) offer competitive technology but lack the production capacity scale to replace Chinese suppliers (E8).
On the Chinese side, Innolight (中際旭創) is described by Technews as the most exposed company to the proposed ban: 57.3% of its 2025 revenue came from the US market, rising further to 61.7% in the first quarter of 2026, with Google, Nvidia (輝達) and Meta among its main customers (E9). CNA's report cited the same 57.3%-to-61.7% progression and customer list (E15).
| Metric | Value | Period |
|---|---|---|
| Innolight (中際旭創) US revenue share | 57.3% | Full-year 2025 |
| Innolight (中際旭創) US revenue share | 61.7% | Q1 2026 |
China's Ministry of Foreign Affairs addressed the proposal directly. Technews quoted spokesperson Lin Jian (林劍) saying China "firmly opposes the US side generalizing the concept of national security and abusing state power to unjustifiably suppress Chinese enterprises" (E5). CNA's report carried the identical quote (E13).
Lin Jian (林劍) also said protectionism cannot raise US competitiveness, and that the US approach seriously hinders normal trade between Chinese and American businesses, which he said does not serve the interests of any party, including US companies and consumers (E6).
The reporting lays out a tension rather than a resolution. On the timeline described by Technews, the FCC ban is still in draft form and could be revised or shelved (E2) — yet the market already priced in the risk, sending Innolight (中際旭創) and Eoptolink (新易盛) shares down 7.27% and 5.29% respectively on the day the news broke (E3, E4). At the same time, the two companies most exposed to a ban are also the market's dominant suppliers: Innolight (中際旭創) at 27% global share (E7) and Eoptolink (新易盛) at No. 2 globally (E10), while the two named US alternatives, Coherent (高意) and Lumentum (朗美通), are described as lacking the capacity scale to replace them outright (E8). Meanwhile, Innolight's (中際旭創) own dependency on the US market — 57.3% of revenue in 2025, rising to 61.7% in Q1 2026 (E9) — runs in the opposite direction of Beijing's public objection to the proposed restriction (E5, E6).
Innolight (中際旭創) closed down 7.27% and Eoptolink (新易盛) fell 5.29% on August 5, 2026, according to Technews, CNA and ETtoday.
27%, the leading position in the global data-center transceiver market, according to Counterpoint Research data cited by Technews and CNA.
57.3% of its 2025 revenue came from the US, rising to 61.7% in Q1 2026, according to Technews and CNA.
According to TechNews and CNA, Winbond Electronics (華邦電) GM Chen Pei-ming warned on August 6, 2026 that 2027 memory shortages will exceed 2026's. CMS revenue rose 78% and Flash revenue rose 65% quarter-over-quarter, backed by NT$39.5 billion in 2026 capex, up over 70-fold year-on-year.
According to Technews, MoneyDJ, and CTEE reports dated August 6, 2026, TSMC (台積電) is holding roughly $1 billion (about NT$32 billion) worth of Apple (蘋果) A20 Pro processors that cannot complete back-end packaging because of a DRAM shortage. TSMC's CFO had already flagged rising inventory days on July 16, and Apple sources memory mainly from Micron, plus SK Hynix and Samsung.
According to MoneyDJ, Taikang Biotech (台康生技, TWSE: 6589) posted July 2026 revenue of NT$211.799 million (about NT$212 million), up 183.97% year-over-year from NT$74.585 million in July 2025. Cnyes reported the same figure with an 86.93% month-over-month gain, while cumulative January–July revenue reached NT$832.545 million, up 70.91% year-over-year. The company attributed the increase to gradual recognition of self-owned product licensing royalties and growth in its CDMO business.
