Cavo twinax DAC passivo ACT 3 m SFP+ - SFP+ codificato per HP / HPE / Aruba / Procurve (J9283A/J9283B/J9283D)

The ACT 3m SFP+ Passive DAC Twinax cable is a 3-meter direct-attach cable with SFP+ connectors on both ends, designed for short-distance, high-speed data links between compatible network devices from HP, HPE, Aruba and ProCurve. Its passive twinax construction provides a low-latency, energy-efficient physical connection suitable for server-to-switch and switch-to-switch links in racks and server rooms. The cable is intended for environments where stable 10Gb/s class connectivity is required over a short reach.

Advantages

The passive design eliminates the need for external power or active transceivers, reducing power consumption and complexity. Native SFP+ terminations ensure straightforward plug-and-play compatibility with equipment that accepts standard SFP+ twinax DACs. The fixed 3 m length simplifies cabling planning in dense rack deployments while offering consistent signal integrity and low latency characteristic of twinax copper interconnects.

Key specifications

How to use

Insert each SFP+ connector firmly into the SFP+ port of the devices to be connected, ensuring that the latch or retention mechanism engages. No additional power or configuration is required on the cable itself; devices may detect the link automatically if their firmware and port settings support passive DACs. Route the cable to avoid sharp bends and excessive mechanical stress, and secure it using cable management fittings appropriate for rack installations.

Recommendations

Verify device compatibility with SFP+ passive twinax DACs from the equipment vendor documentation before installation. Use the ACT 3m cable for short, intra-rack or adjacent-rack connections where cost, power savings and low latency are priorities. For longer distances or where optical isolation is required, consider choosing active optical cables or fiber transceivers instead.
