The massive AI-driven supercycle has fueled explosive growth across the optical module supply chain. Yet, the mid-year 2026 earnings reports from the so-called "Easy-Zhong-Tian" trio—Zhongji Innolight, Eoptolink Technology, and Suzhou Tfc Optical Communication Co., Ltd.—reveal a notable divergence, with TFC's second-quarter revenue unexpectedly declining quarter-over-quarter. What underlying challenges does this performance gap expose?
The divergence among the trio largely stems from a mismatch between their positions in the industrial chain and the current technology cycle. System integrators like Zhongji Innolight and Eoptolink directly capture orders from the AI compute boom, giving them much greater revenue elasticity. On the other hand, TFC's upstream supply chain resilience appears weaker than its peers', as its active component business was hampered by material shortages, and its inventory and prepayment growth lagged significantly behind the other two—highlighting a comparatively weaker ability to secure critical components.
As the 2026 semi-annual reporting season concluded, the performance reports from the optical module "Easy-Zhong-Tian" trio—Zhongji Innolight, Eoptolink Technology, and Suzhou Tfc Optical Communication Co., Ltd.—showed clear signs of divergence.
Performance Diverges: TFC Lags Behind
According to the 2026 half-year financial report, Zhongji Innolight achieved revenue of 41.778 billion yuan, up 182.49% year-on-year. Net profit attributable to shareholders reached 13.651 billion yuan, a surge of 241.7%, with a gross margin of 46.25% for the first half, an increase of 6.92 percentage points. On a quarterly basis, Q2 revenue for Zhongji Innolight was 22.281 billion yuan, up 174.57% year-on-year and 14.29% quarter-on-quarter. Q2 net profit hit 7.917 billion yuan, up 228.19% year-on-year and 38.03% sequentially.
During the same period, Eoptolink Technology recorded first-half revenue of 20.91 billion yuan, a 100.34% increase year-on-year. Net profit attributable to shareholders was 7.529 billion yuan, up 90.98%, with a gross margin of 48.44%, a 1.01 percentage point improvement. Quarterly figures show Eoptolink's Q2 revenue at 12.572 billion yuan, growing 96.9% year-on-year and 50.78% sequentially, while net profit reached 4.749 billion yuan, up 100.4% year-on-year and 70.81% quarter-on-quarter.
Suzhou Tfc Optical Communication Co., Ltd. released its 2026 semi-annual report, posting revenue of 2.828 billion yuan, up 15.15% year-on-year. Net profit attributable to shareholders was 1.204 billion yuan, an increase of 33.92%, with a gross margin of 60.87% for the period, up 10.08 percentage points. However, on a quarterly basis, TFC's Q2 revenue was 1.498 billion yuan, representing a negative growth of 0.9% year-on-year, though it increased 12.58% sequentially. Q2 net profit was 712 million yuan, up 26.79% year-on-year and 44.66% quarter-on-quarter.
The optical module industry chain is typically divided into upstream (optical and electrical chips), midstream (optical components and modules), and downstream (cloud vendors and equipment makers). It's worth noting that Zhongji Innolight and Eoptolink are the "duopoly of module integrators," while TFC occupies a "core first-tier upstream position." They are grouped together because all three benefit deeply from the AI optical interconnect boom and control key value-added segments. However, in terms of revenue performance, TFC lagged behind in both half-year and quarterly growth rates compared to its peers.
Explosive Demand Yet TFC's Q2 Revenue Declines
Optical module demand has surged thanks to the expansion of computing power. Large-scale AI clusters require terabyte-per-second data exchanges between GPUs, where traditional copper cables fall short on bandwidth, heat, and distance. Optical transmission offers superior bandwidth, lower latency, longer reach, and reduced power consumption, making it essential for GPU cluster interconnects. Thus, optical module makers are direct beneficiaries of AI capital expenditure.
Since late 2022, the rapid development of large language models has pushed compute demand to new heights, driving the deployment of high-performance, large-scale computing clusters to support AI training and inference. With trends like multimodal LLMs, agentic AI, and physical AI emerging, daily token consumption has grown 30-fold from 3 trillion at the end of 2023 to 100 trillion by 2025, and is projected to surge another 80-fold to 8,000 trillion by 2030. To meet this demand, cloud service providers worldwide are ramping up capital spending. In Q2 2026 alone, Microsoft, Amazon, Meta, and Google collectively invested $164.9 billion, up approximately 86% year-on-year. According to CIC Consulting forecasts, global cumulative AI capital expenditure is expected to reach $4.7 trillion between 2026 and 2030, more than five times the previous five-year period.
This data clearly shows that the explosive growth in AI compute demand is driving the optical module industry into an unprecedented super-cycle. While the growth rates of Zhongji Innolight and Eoptolink align with industry demand, TFC's Q2 revenue turned negative. Why?
Is Supply Chain Resilience the Internal Issue?
From an external perspective, different positions in the industry chain lead to varied revenue elasticity. TFC sits at a different point than Zhongji Innolight and Eoptolink. The latter two are module integrators directly serving overseas cloud giants, benefiting from high unit value and large order volumes. TFC, however, is an upstream optical component and optical engine supplier, operating in a "shovel-selling" role. Industry insiders note that integrators are the first to receive AI compute orders, and when demand spikes non-linearly, their revenue elasticity naturally exceeds that of upstream component makers.
Looking at technology evolution, AI-driven data center upgrades are accelerating industry iteration. Companies must rapidly migrate to 800G, 1.6T, and future 3.2T architectures to meet higher-density, higher-throughput interconnect needs. Simultaneously, new technologies like silicon photonics, thin-film lithium niobate, and CPO are emerging to address power, heat, cost, and reliability demands at high speeds. TFC focuses on upstream FAU, optical engines, and CPO supporting components, but large-scale penetration of next-gen products like CPO/NPO may not occur until 2027-2028. According to LightCounting research, CPO large-scale deployment is likely to begin in 2027, with actual deployment possibly delayed to September 2028. In contrast, Zhongji Innolight's 1.6T silicon photonics modules are already "entering the volume ramp phase, with shipments climbing quarterly and becoming the core revenue growth driver."
Furthermore, is TFC's supply chain resilience weaker than that of Zhongji Innolight and Eoptolink? The 2026 half-year report reveals structural divergence within TFC's products. Passive optical component revenue was 1.53 billion yuan, up 77.40% year-on-year, but active optical component revenue fell to 1.26 billion yuan, a decline of nearly 20%. In investor communications, TFC stated that its active product line faced lower capacity utilization in the first half due to temporary supply shortages of certain materials. The company has been actively coordinating resources to resolve supply constraints, noting that bottleneck materials have improved and capacity utilization is gradually recovering.
Optical chips are categorized into active and passive types, with active chips further divided into laser, detector, and modulator chips. In a narrow sense, optical chips usually refer to laser and detector chips due to their highest technical barriers and value share. Optical chips are core components of modules, and their value share increases significantly with higher speeds. This suggests that high-speed optical modules are no longer "labor-intensive assemblies" but increasingly resemble system-level precision devices driven by high-value optical chips. This explains why upstream EML, CW light sources, silicon photonics wafers, and detectors remain in tight supply, and can even dictate the shipment capabilities of leading integrators.
Against a backdrop of explosive demand and scarce upstream components like high-end EML, DSP, CW sources, and photodetectors, securing upstream supply is crucial for determining shipment and revenue generation capabilities. Does this imply TFC's supply chain management resilience needs improvement? Notably, Zhongji Innolight lists its reliable and robust supply chain as a core competitive advantage. By collaborating closely with top-tier suppliers, it has built a stable global supply chain. For all raw materials, it selects leading suppliers to create an industry-leading ecosystem. Additionally, multi-year framework agreements with industry partners ensure stable and reliable key material supply, even during peak demand periods. Long-term, win-win strategic partnerships with suppliers, including support for their technology roadmaps and international expansion, further strengthen supply chain stability and cost competitiveness.
How does TFC's "material-locking" capability compare among the trio? Inventory and prepayment figures offer some insight. In the first half of this year, TFC's prepayments were 96 million yuan, surging over 10-fold year-on-year, while inventory was 929 million yuan, up 154%. Meanwhile, Zhongji Innolight's prepayments were 954 million yuan, up more than 15 times, with inventory at 19.8 billion yuan, up over 116%. Eoptolink's prepayments were 870 million yuan, a 313-fold increase, with inventory at 11.6 billion yuan, up 96%.
TFC noted in its investment briefs that temporary supply shortages of certain materials affected its active component production ramp-up in the first half. In response, the company took proactive measures, including onboarding new suppliers to ensure stable delivery of core materials. As of the third quarter of 2026, material shortages have gradually eased, with overall supply improving. Going forward, TFC will continue to strengthen supply chain management for risk materials, focusing on "ensuring delivery" to enhance material security and better support customer production ramp-up needs.
