zQSFP+ Overview
 The zQSFP+ (z-Quad Small Form-factor Pluggable Plus) connector and cage assembly is a high-density, high-speed product solution designed for applications in the telecommunications, data center and networking markets. The interconnect offers four channels of high-speed differential signals with data rates ranging from 25 Gbps up to potentially 40 Gbps, and will meet 100 Gbps Ethernet (4x25 Gbps) and 100 Gbps 4X InfiniBand Enhanced Data Rate (EDR) requirements.
To make system upgrades simple and effortless, the zQSFP+ interconnect is backwards-compatible with existing, broadly-established QSFP+ optical modules and cable assemblies. Designed with an enhanced electromagnetic interference (EMI) cage, the product helps to provide excellent thermal performance and EMI protection. Through a coupled, narrow-edged, blanked- and formed- contact geometry and insert molding design, the zQSFP+ interconnect exhibits superior signal integrity, mechanical and electrical performance. It can be used in current 10-Gbps and 16-Gbps applications with substantial margin.
The zQSFP+ connector and cage assembly is offered as a dual source option with Molex Incorporated.
