The HP 720202-B21 is a 5-meter direct attach copper (DAC) cable designed for high-speed interconnect between QSFP+ ports. It supports 40Gb/s throughput and is compatible with HP/HPE networking infrastructure, including the 5930 and 7900 series switches, as well as most third-party equipment with QSFP+ interfaces. This cable eliminates the need for separate optics modules, reducing latency and cost for short-distance connections in data center and enterprise environments. Typical applications include switch-to-switch stacking, switch-to-server connections, and direct server-to-storage links where cable runs do not exceed 5 meters.Part Number: HP 720202-B21 | Form Factor: QSFP+ male to QSFP+ male | Cable Length: 5m | Data Rate: 40Gb/s | Technology: Direct Attach Copper (DAC) | Passive design requiring no power.All units are tested and guaranteed working.
