The IBM 49Y7934 is a 1-meter passive direct attach copper (DAC) cable designed for high-speed interconnect applications. It features QSFP+ connectors on both ends, supporting 40Gb/s throughput and compatible with IBM System x servers, storage arrays, and networking equipment featuring QSFP+ ports. This cable eliminates the need for separate transceivers in short-reach deployments, reducing power consumption and latency while providing a cost-effective alternative to active optical cables. Typical use cases include server-to-switch connections, storage area network (SAN) implementations, and high-performance computing (HPC) fabric builds within data center environments. Part number 49Y7934; 1-meter length; passive copper construction; supports full 40Gb/s line rate with minimal signal degradation over short distances.Tested and guaranteed; available via quote.
