Molex zQuad Small Form-factor Pluggable Plus (zQSFP+TM) interconnect solution is designed for high-density interconnect applications and conforms to SFF-8665 QSFP28. Components of the system include SMT connectors; and stacked integrated 2-by-1, 2-by-2 and 2-by-3 connectors and cages. Molex's zQSFP+TM SMT connector supports new 100 Gbps Ethernet and 100 Gbps InfiniBand* (IB) Enhanced Data Rate (EDR) applications. EDR applications consist of four lanes of high-speed differential signals with individual data rates at 25 Gbps. The preferential coupling design uses a narrow-edge coupled, blanked- and formed-contact geometry and insert molding to optimize electrical performance. The zQSFP+TM connector shares the same mating interface as the QSFP+ form factor, making it backward compatible with current connectors, cages and cable assemblies. zQSFP+TM EMI cages are designed with an advanced heat-sink system to provide a high level of heat dissipation for next-generation system-power levels. Die-cast design features screw-down option to the PCB for maximum board retention. The spring-finger design provides optimal EMI grounding and allow for more space to route high-speed traces.
