2057042-1 is a QSFP+ ganged cage designed for high-speed data communications applications. This 1x3 port configuration features behind bezel mounting with dual lightpipes applied per port and supports Networking, PCI, and SAN heatsink options. The cage requires a 38-position SMT connector to complete the assembly and uses customer-applied EMI gasket suppression. Common applications include 10Gb Ethernet, 14Gb InfiniBand FDR, and other high-density data center networking equipment where 3x the density of SFP+ interconnects is required.
