The thermal performance of the Quad Small Form Factor Pluggable Double Density (QSFP-DD) module has been extensively evaluated for use in a high-performance data center environment. Thermal test data and results for the feasibility of 15W QSFP-DD modules have been presented and analyzed showing temperature rise versus airflow.

The QSFP-DD is the industry’s smallest 400GbE (Gigabit Ethernet) module and provides the highest port bandwidth density. Developed in collaboration with the
