Siemon Interconnect Solutions CXP Copper Cable assemblies were developed for high-density applications, offering a cost-effective, low-power option for high-speed data center interconnects. The CXP form factor can replace up to three standard QSFP+ connections, providing greater density and reduced system cost. These direct attached assemblies support 12 channels of 10Gb/s (QDR) for 120Gb/s Infiband, or 10 channels of 10Gb/s for 100Gb/s (IEEE 802.3ba) and are available in standard lengths up to 4 meters with longer custom lengths available.

  • InfiniBand 12xSDR, 12xDDR, 12xQDR
  • Ethernet 10G,40G, 100G
  • Rack-to-Rack, Shelf-to-Shelf Interconnect
  • Networking, NIC
  • Storage: DAS, SAN, NAS
