Built in Taiwan – TAA-Compliant, Low Tariff Advantage

Optech’s transceivers are proudly manufactured in Taiwan, giving you major benefits in global supply chain and compliance:

  • 🇹🇼 TAA-Compliant
    Fully aligned with the Trade Agreements Act (TAA), making Optech modules eligible for U.S. federal contracts and public sector procurement.

  • 📉 Lower Tariffs
    Taiwan-origin products help customers avoid the 25–34% additional tariffs applied to China-origin transceivers under U.S. Section 301. This translates to significant long-term savings for data center operators and integrators.


Superior Flexibility for Global OEMs and Hyperscalers

  • 🔧 Custom Labeling & Branding – Private-label or white-label options for OEM and system integrators

  • 🧪 Rigorous Testing & Compatibility – Fully validated in leading platforms such as NVIDIA Spectrum, Cisco Nexus, Arista 7060, and more

  • 🔁 Quick Sample Turnaround – Fast prototyping, flexible MOQ, and support for urgent deployments

  • 🌎 Global Reach – Warehousing and support teams across the U.S., Europe, and Asia-Pacific
