The global QSFP-DD Packaged Optical Module market size is expected to reach $ million by 2031, rising at a market growth of %CAGR during the forecast period (2025-2031). In this report, we will assess the current U. tariff framework alongside international policy adaptations, analyzing their. QSFP-DD (Quad Small Form Factor Pluggable Double Density) is a small pluggable optical module that supports double-density interfaces and is designed for 400G Ethernet applications. The QSFP-DD package complies with the IEEE 802. 3bs standard and the QSFP-DD MSA (Multi-Source Agreement). SHENZHEN WALSUN OPTICS TECHNOLOGY CO. High-density 800G OSFP and QSFP-DD transceivers support InfiniBand and RoCE, enabling 100m to 2km transmission via MMF and SMF.
