The 2274000-1 is a single-port (1x1) press-fit cage for the zSFP+ pluggable I/O interconnect system, which supports data rates up to 28 Gbps NRZ and 56 Gbps PAM-4. This cage is specifically designed with integrated EMI spring fingers for effective shielding and includes an option for light pipes, though it does not have a heat sink option. Made from Nickel Silver, the cage is backward-compatible with SFP+ connectors, allowing for easy system upgrades. Its robust design is suitable for applications in telecommunications, data centers, and networking where high-speed data integrity is critical.
