QSFP+ Passive Copper Cables for Intel® Ethernet Converged Network Adapters (Intel® Ethernet CNA).
Intel offers Intel® Ethernet QSFP+ passive copper cables for customers who would like to deploy Intel® Ethernet Converged Network Adapters (Intel® Ethernet CNA) with a QSFP+ direct attach cable. Intel® Ethernet Converged Network Adapters with QSFP+ connectivity deliver proven, reliable solutions for deployments of high-density Ethernet for unified 10 GbE network connections. These QSFP+ adapters use the latest PCI Express* v3.0 bus technology for maximum bandwidth and address the increasing capability of the latest Intel® Xeon® processor E5 and E7 family-based platforms.
Intel® Ethernet QSFP+ Twinaxial Cables are 40GBASE-CR4 802.3ba-qualified passive copper cables that provide next-generation performance by combining four 10 Gb/s SFP+ channels into one affordable, high-density QSFP+ package. Intel® Ethernet QSFP+ Breakout Cables offer IT professionals a cost-effective interconnect solution for merging 40 GbE QSFP+ and 10 GbE SFP+ adapters, switches, and servers. Each cable features a single QSFP+ connector (SFF-8436) rated for 40 Gbps on one, and four SFP+ connectors (SFF-8431), each rated for 10 Gbps, on the other. This cable type allows customers to bridge the gap between 10 GbE and 40 GbE cables, switches, and adapters, and economically links a QSFP+ port with an upstream 10 GbE SFP+ switch.
