DESCRIPTION

2343246-3 is a 2x1 QSFP-DD cage assembly with heatsink spring designed for high-speed 400G pluggable I/O solutions in data center and high-performance computing applications. This stacked configuration provides an eight-lane electrical interface capable of 28 Gbps NRZ or 56 Gbps PAM-4 to achieve 200 or 400 Gbps aggregate per port, with backwards compatibility allowing existing QSFP modules to be plugged into QSFP-DD ports. The assembly features a proprietary heatsink design optimized for thermal performance in 15-18W applications, with heatsink options available in three standard heights: PCI (4.2 mm heatsink height, 13.7 mm total height), SAN (6.5 mm heatsink height, 16 mm total height), and NET (13.5 mm heatsink height, 23 mm total height). Heatsinks are available in extruded aluminum or thermally enhanced ZIP fin configurations, with 1, 2, and 4 lightpipe configurations available upon request. This solution is ideal for servers, switches, routers, and data center deployments requiring superior thermal and signal integrity performance.
