The 2342934-3 is an advanced 1x1 QSFP-DD (Quad Small Form-factor Pluggable Double Density) Cage Assembly, engineered to provide the critical mechanical, electromagnetic, and thermal infrastructure required for next-generation 400G and 800G networking equipment. Designed to house high-speed optical transceivers and Direct Attach Copper (DAC) cables, this single-port receptacle is an essential physical layer (PHY) component for modern Top-of-Rack (ToR) switches and core routing platforms.
Because QSFP-DD modules can draw up to 15W-25W of power, thermal management is the primary engineering challenge. To address this, the 2342934-3 is equipped with an integrated 13.5mm networking-style zipper heatsink. Unlike standard extruded heatsinks, zipper-fin technology allows for an exceptionally high fin density and increased surface area. This specific "networking" profile is optimized for side-to-side or front-to-back airflow configurations typical in 1RU and 2RU server chassis, ensuring superior thermal dissipation and preventing optical module thermal throttling under heavy data loads.
Mechanically, the cage is constructed from robust Stainless Steel, offering superior rigidity to withstand the heavy insertion and extraction forces of thick 400G DAC bundles while providing a strict 360-degree EMI seal around the bezel. For PCB mounting, the assembly utilizes a solderless Press-Fit termination featuring 1 Rear EON (Eye-of-Needle) per port column. This EON press-fit design is crucial for high-speed networking: it eliminates the extreme thermal stress associated with wave soldering on the expensive, high-layer-count PCBs required for 400G routing, while ensuring highly reliable, long-term mechanical retention.
Operating flawlessly in high-density environments, the 2342934-3 QSFP-DD cage is the definitive structural solution for cloud data centers, AI computing clusters, 5G telecom infrastructure, and high-performance enterprise edge switches.
