PAGE 2DATA AND DEVICES / / / QSFP28/56 AND zQSFP+ INTERCONNECTS QSFP28/56 and zQSFP+ Interconnects Enhanced QSFP28/56 and zQSFP+ Cages Lower Assembly Insertion Force Help increase assembly throughput by providing a 55% reduction in force needed to insert the line card into the front bezel. The reduction in insertion force makes assembly easier, faster, and reduces the risk for damage which can lead to reduced EMI performance. Improved EMI Performance EMI sealing enhancements on these new cages provide 10 dB EMI performance improvement over current QSFP28 products. High-performance springs are both fl exible and strong Improved springs more fully seal connector from EMI Reference base part number 2170709 on page 7 EMI Enhanced Thermally Enhanced Lower Port Cooling Internal riding heatsink in the seperator plate area provides enhanced cooling to the lower ports and a 12-15oC improvement over standard stacked zQSFP+ cages. Optimized Airfl ow External riding heatsinks on the upper port are optimized for airfl ow direction (also available without heatsinks). Air vent holes allow for air to pass through and exit out the sides and rear of the cage.

Designing with these cages allows access to proven technology to support high performance applications. High Density Certain stacked cages can be used in belly-to-belly applications to support high density 2RU+ box designs and switch designs using next-gen 48 and 64 silicon ports. Low Cost Using a stacked belly-to- belly design enables single PCB architecture versus two PCBs per line card, saving signifi cant system costs.
