This article explores various strategies to enhance heat dissipation in QSFP modules, including using air deflectors, changing heatsink materials, increasing surface area, and incorporating heat pipes. The QSFP-DD is a new package of high-speed pluggable modules whose specifications were released in 2016 and received a lot of attention, and after several modifications, QSFP-DD products became available in 2018. The package's electrical interface has 8 channels and can be used for 200 or 400G. Efficient heat dissipation is crucial for the reliable performance and longevity of high-speed optical modules like the QSFP (Quad Small Form-factor Pluggable). Inadequate heat.

QSFP-DD1600 establishes a roadmap for systems and pluggables to improve cooling capacity thanks to a wide array of thermal innovations. 【Methods】The article adopts Flotherm simulation analysis to establish the numerical. Telcordia NEBSTM Requirements: Physical Protection GR-63 CORE outlines the temperature range for a touchable surface in normal use (short periods) as 55°C for a metal surface and 70°C for non-metals such as the pull handle of the module. Parts that are held in normal use (prolonged use) are.
