R9D20A

10 G SFP+ to SFP+ 3 m Direct Attach Copper (DAC) Cable

The HPE Aruba R9D20A DAC Cable is a passive twinax copper cable designed specifically for 10 G SFP+ ports, offering a reliable and cost-effective point-to-point connection between switches, servers, or storage devices. With a 3 m length, it's ideal for short-range rack and adjacent-rack setups, enabling ultra-low latency and high bandwidth performance without needing expensive transceivers.

Features

Engineered for agile deployment in data centers and SMB environments, the R9D20A delivers wire-speed 10 GbE connectivity using dual SFP+ connectors. As a passive DAC, it draws no power, reduces heat output, and provides shorter latency compared to active or fiber links. Aruba and Instant On switches automatically detect and configure the connection, ensuring seamless interoperability×no manual firmware tweaks required .

Advanced Options

Supporting a data rate from 1.25 Gbps up to 10.52 Gbps and functioning within a commercial temperature range of 0 °C to 70 °C, this cable is suitable for a variety of internal networking tasks such as switch-to-switch uplinks, server connections, and SAN environments .

Product Key Features

• Dual SFP+ to SFP+ 10 G DAC, length = 3 m
