The HP 8121-1179 is a 3-meter direct attach copper (DAC) cable designed for short-range, high-speed interconnects in data center and enterprise environments. This cable terminates in XFP and SFP+ connectors, enabling compatibility with a wide range of HP networking equipment, switches, and transceivers that support these form factors. Rated for 10 Gbps throughput, the direct attach architecture eliminates the need for separate transceivers, reducing cost and complexity while maintaining signal integrity over distances up to 3 meters—ideal for rack-to-rack connections or equipment within close proximity.The cable suits organizations standardizing on XFP/SFP+ infrastructure for legacy and mid-generation switch deployments, offering passive connectivity with minimal latency. Typical applications include server-to-switch uplinks, storage array connections, and fabric consolidation in enterprise IT environments.Tested and guaranteed working; available via quote.
