2-2339978-0 is a zSFP+ Stacked (SFP56) cage assembly with integrated connector designed for high-speed pluggable I/O signal applications. The assembly features a stacked cage configuration with 8 ports arranged in a 2×4 matrix, accommodating 20 total positions with a 0.6 mm centerline pitch. It supports maximum data rates of 56 Gb/s and operates reliably across a wide temperature range of -55°C to +105°C. The connector includes integrated EMI springs for electromagnetic interference containment and an included lightpipe for signal integrity. Termination options include both through-hole press-fit and solder methods, making it suitable for diverse PCB integration requirements in high-speed networking, data center, and telecommunications equipment where compact, multi-port connectivity is essential.
