Thai manufacturer of active optical equipment QSFP-DD

Currently, there is no publicly documented Thai manufacturer of QSFP-DD active optical equipment; most suppliers are based in Taiwan, China, or other regions.

QSFP-DD (Quad Small Form-factor Pluggable Double Density) is a high-speed optical module standard designed for 400G, 800G, and higher data rates, supporting both Ethernet and InfiniBand applications . Active Optical Cables (AOCs) using QSFP-DD form factors are widely used in data centers for short-range interconnects, offering advantages such as lower weight, smaller bend radius, and improved airflow compared to copper cables . These cables are typically available in multimode fiber types (OM3, OM4) and lengths ranging from 1 meter up to 100 meters . Major manufacturers of QSFP-DD AOCs include Optech Technology (Taiwan), which provides 400G QSFP-DD AOCs optimized for high-density deployments, and QSFPTEK, which offers breakout cables and generic compatible 400G QSFP-DD AOCs for data center and HPC environments . These products are fully compliant with IEEE 802.3cd standards and QSFP-DD MSA specifications, ensuring interoperability across multi-vendor switches and transceivers . For sourcing in Thailand, companies often rely on regional distributors or resellers of these international manufacturers rather than local production. Thai-based networking or telecom firms may import QSFP-DD AOCs from Taiwan, China, or Singapore to meet local data center requirements. If a Thai manufacturer exists, it is not widely publicized or listed in standard industry directories. Recommendation: For procurement in Thailand, consider contacting authorized distributors of Optech or QSFPTEK, or regional electronics suppliers that stock QSFP-DD active optical cables. This ensures access to certified, high-performance products compatible with 400G and higher networking standards.
