Detailed Specifications
HPE Aruba R0M46A - 50GBase SFP56 to SFP56 Direct Attach Copper Cable
Overview :
The HP R0M46A is a 0.65-meter passive direct-attach copper (DAC) cable designed to link two SFP56 ports at up to 50 Gbps for short-range interconnects. Data centre engineers and network architects use this cable for stack or switch-to-switch connectivity within racks, especially where latency and cost-per-link matter. The cable supports 50G data rate and uses twinax copper construction, making it suitable for high-density 50G-capable switch platforms. Its length is optimized for intra-rack or adjacent-rack links×allowing direct comms without separate transceivers or fibre. It is listed as compatible with specific HP/Aruba SFP56 ports, and should be used in 50G-enabled port groups as defined in the vendor's compatibility matrix.
Key Features :
Supports 50 Gbps data rate over SFP56 twinax copper
Passive twinax design ideal for direct rack interconnects
0.65 m (≈2.13 ft) length for short-reach rack-to-rack links
SFP56 connectors on both ends, male gender
Commercial temperature rating 0 °C to 70 °C
