QSFP+ Passive Direct Attach Copper Cable assemblies were developed for high-density applications, offering a costeffective, low-power option for high-speed data center interconnects. The QSFP+ form factor can replace up to four standard SFP+ connections, providing greater density and reduced system cost. The direct-attach assemblies support emerging 40Gb/s applications and are available in standard lengths up to 10 meters with longer custom lengths available
