HPE R0M47A Aruba Direct Attach Cable (DAC) SFP56 to SFP56 50 Gb

HPE R0M47A – 50 Gb SFP56‑to‑SFP56 3 m DAC Cable

Overview   

The HPE R0M47A is a passive twinax direct‑attach copper cable of length 3 metres, designed for linking two compatible SFP56 ports in high‑speed network equipment (for example access/aggregation or ToR switches). If you’re connecting two switches in the same rack or adjacent racks and need a cost‑effective short‑reach link with 50 Gb/s capability, this cable fits the bill. It suits wiring‑room or data‑centre use where a short copper run is sufficient and fibre optics may be unnecessary. The cable supports 50 Gb Ethernet speeds, while being backwards‑capable for 25 Gb or 10 Gb depending on port and system configuration. It is compatible with SFP56 ports on the HPE/Aruba equipment that supports 50G mode.

Key Features

• 3‑metre length: provides flexibility for short‑reach connections between two SFP56 ports without external transceivers.

• 50 Gb/s nominal data rate support: enables high‑capacity stacking or switch‑to‑switch links.

• SFP56 form‑factor to SFP56 form‑factor: plugs directly into compatible SFP56 ports on switches.

• Passive twinax copper construction: lower cost and power compared to optical modules, ideal for short links in wiring‑rooms.

• Multi‑rate capable: while rated for 50G, can operate at 25G or 10G depending on platform port speed configuration.
