Suzhou TFC Optical Communication Co., Ltd. (300394.SZ): Mission and Values
Suzhou TFC Optical Communication Co., Ltd. (300394.SZ) is organized around two core business segments that together address the needs of hyperscale cloud, telecom, data center interconnects and optical access markets. How It Works- Two primary segments: Optical Device Overall Solutions and Optoelectronic Advanced Packaging.
- Optical Device Overall Solutions delivers high-speed optical engine solutions (coherent and PAM4 modules) and passive sub-assembly (PSA) solutions for pluggable transceivers and board-level packages.
- Optoelectronic Advanced Packaging concentrates on micro-optics technology, advanced chip-to-package integration, and low-loss optical interconnect modules.
- Vertically integrated manufacturing: TFC produces critical components in-house (micro-optics, sub-assemblies, optical benches, packaging substrates and test/jig fixtures) to control yield, quality and cost.
- Strategic technology partnerships (example: OpenLight) accelerate development of next-generation optical engines, co-packaged optics (CPO) enablers and advanced photonic integration.
- Global footprint and supply-chain risk management: manufacturing sites in China and Thailand plus international procurement channels reduce single‑country exposure and support continuity for global customers.
- Product sales of optical engines, modules and packaged sub-assemblies: headline revenue stream driven by unit volume, module ASPs and migration to higher-speed generations (100G→400G→800G+).
- Value-added advanced packaging services (micro-optics assembly, alignment and wafer-level packaging): higher margin service and IP-led revenues.
- Long-term OEM/ODM supply agreements and design wins with cloud, telecom and enterprise customers underpin recurring volume.
- R&D and technology licensing/partnerships provide roadmaps to higher-performance products and platform reuse across generations.
