Summary of Conference Call on Optical Networking Industry Industry Overview - The optical networking industry is expected to experience a super upcycle driven by the adoption of ASIC (Application-Specific Integrated Circuit) and SiPh (Silicon Photonics) technologies, with significant demand growth anticipated for 800G and 1.6T transceivers in 2026, projected at 45 million and 8 million units respectively [1][2][13]. Key Companies Discussed 1. **Innolight (300308.SZ)** - Top pick in the sector due to strong market share and margin upside from technology upgrades [1][4]. - Expected gross/net margin could reach approximately 45% due to BOM (Bill of Materials) optimization and lower costs associated with SiPh technology [39][41]. - Revised earnings estimates for FY25-27E show an increase of 25%-85% due to higher shipment numbers and margin improvements [41][43]. 2. **Eoptolink (300502.SZ)** - Anticipated to gain market share with a significant shift towards SiPh technology, expected to reach a mix of ~40% in 2026 [32][69]. - Target price raised to Rmb321 based on a 20x FY26E PE, reflecting strong growth in 800G and 1.6T segments [33][70]. - Earnings estimates for FY25-27E increased by 5-25% due to higher revenue and margin assumptions [33][43]. 3. **Suzhou TFC Optical Communication (300394.SZ)** - Focus on acquiring new customers for passive optical components and optical engines, with a target price raised to Rmb140 [46]. - Earnings estimates for FY25-27E increased by 6-42% based on stronger demand for 1.6T optical engines [46][48]. Core Insights and Arguments - The ASIC uptrend is expected to solidify the demand for optical transceivers, particularly with the increasing attach rate per AI accelerators [2][11]. - The market has underappreciated the gross/net margin upside from SiPh migration, which is projected to drive sector EPS revisions and re-ratings [2][3][11]. - Despite concerns about AI capex peaking, the inference AI capex is viewed as more sustainable, supporting ongoing growth in the optical networking sector [3][28]. - Customer preference remains strong for Tier-1 suppliers like Innolight and Eoptolink, which is expected to enhance their market positions [40][30]. Additional Important Points - The anticipated adoption of LPO (Linear-drive Pluggable Optics) for scaling up ASICs could represent an upside risk for long-term demand [12]. - The actual mass adoption of co-packaged optics (CPO) is not expected until 2029-2030, allowing for continued strength in the 800G market in 2026 [30]. - The gross margin for 800G/1.6T SiPh transceivers is expected to reach 45-50%, driven by ongoing technology upgrades and increased industry penetration [30][31]. Conclusion - The optical networking industry is poised for significant growth driven by technological advancements in ASIC and SiPh, with leading companies like Innolight and Eoptolink positioned to capitalize on these trends.
