Accelink supplies optical communications products across transmission, access and datacom product lines. These products provide optical interconnect components and systems for telecom and data-center networking.
Darker bar: ahead of the other company on that measure.
Accelink is the most vertically integrated of the Chinese optical names and ranks fifth globally in the top-ten optical module list published in its 2025 placement prospectus, behind Innolight (first), Eoptolink (third) and Huawei (fourth), ahead of Hisense Broadband, HG Genuine and Source Photonics. The integration is the distinguishing feature: in-house capability across FP, DFB, EML, VCSEL, PD, APD and SiP chip types, and across COB, hybrid integration, planar waveguide and MEMS packaging, running from optical chips through devices and modules to complete subsystems, including an in-house LCoS chip for flex-grid wavelength selective switches. Its product range spans 10G to 800G for cloud and enterprise data centers, with 400G VR4/DR4/FR4/LR4, 800G DR8/2xFR4/LRO/LPO, and 1.6T DR8. FY2025 revenue was RMB 11.929 billion, up 44.20 percent, with net profit attributable RMB 946 million, up 43.10 percent, basic EPS RMB 1.21, driven by surging datacom module demand under the global AI compute wave and heavy domestic cloud spending, with leading bid share among top-tier domestic customers. Q3 2025 net profit of RMB 347 million was an all-time quarterly record, up 35.42 percent year over year and 56 percent sequentially. Q1 2026 revenue was RMB 2.773 billion, up 24.79 percent, net profit RMB 240 million, up 59.76 percent. Operating cash flow rose 353.99 percent in FY2025.

T&S Communications develops and mass-produces passive and active optical devices, including 1.6T optical engines and CPO components, for data-center networking.
Darker bar: ahead of the other company on that measure.
T&S is the quiet outlier in this cluster: a component and packaging supplier rather than a module brand, and by a wide margin the most profitable company in the Chinese optical chain. FY2025 revenue was RMB 5.163 billion, up 58.79 percent, with net profit attributable RMB 2.017 billion, up 50.15 percent, both all-time highs, at a net margin of 39.08 percent and a return on invested capital of 40.58 percent. Those are semiconductor-IP-like returns earned on optical hardware, indicating real pricing power in optical engine packaging rather than the thin-margin module assembly the category is usually associated with. Active optical device revenue reached RMB 2.997 billion, up 81.11 percent, at 58.06 percent of revenue on higher-speed active deliveries, while passive devices contributed RMB 2.084 billion, up 32.23 percent at 40.37 percent. Operating cash flow was RMB 1.868 billion, up 47.97 percent, and R&D spend was RMB 267 million. The technology record is on the CPO transition path: completed volume production of 1.6T optical engines and finished development of CPO-supporting optical devices for next-generation supercomputing and AI cluster applications, with R&D on multi-channel components for CPO-ELS module applications and on silicon photonics integration. Its Thailand Phase 2 plant enters large-scale production in 2026. The visible drag is Q4, where foreign exchange losses raised financial expenses and stage-specific material supply bottlenecks constrained output, leaving
