## Long description

The Direct Attach Cable HPE Aruba R0M46A SFP56 to SFP56 Passive 50G 1m Blue is a 1 metre twinaxial copper cable with SFP56 connectors designed for short-reach, high-speed interconnects in networking environments. This passive 50G DAC provides a direct, low-latency link between compatible SFP56 ports in switches, routers and network interface modules. The blue jacket aids identification in racks and cabling runs while the compact, one-metre length is suitable for connections within a single rack or between adjacent racks.
Advantages
The cable delivers a reliable 50G connection with low power consumption because it is passive and does not require external power or optical transceivers. Its SFP56-to-SFP56 terminations ensure compatibility with standard SFP56 ports, providing consistent electrical performance and reduced signal loss compared with longer copper assemblies. The short 1m length reduces clutter in rack environments and simplifies cable management while the robust twinaxial construction offers mechanical stability for repeated insertion and removal.
Suitable for
Interconnecting SFP56 ports within a single rack
Connecting adjacent racks in data center rows
High-density switch-to-switch or switch-to-server links
Environments where low-latency, short-reach 50G connections are required
Key specifications
Type: Passive twinaxial direct attach cable (DAC)
Connector interface: SFP56 to SFP56
Data rate: 50 Gbps
Length: 1 metre
Cable colour: Blue
Application: Short-reach, intra-rack and adjacent-rack networking
How to use
Install the cable by inserting each SFP56 connector into the corresponding SFP56 port until the latch engages. Ensure both devices are powered down or follow hot-swap procedures recommended by the equipment manufacturer if live insertion is supported. Verify link status through the network equipment’s management interface and ensure port settings match the 50G operation. Route the cable to avoid sharp bends and mechanical stress; maintain a minimum bend radius as recommended for twinaxial copper cables.
Usage recommendations
Use this 1m passive 50G DAC for short-distance, high-throughput connections where optical transceivers are not necessary. Confirm compatibility with your switch or server vendor and check port firmware or compatibility lists if applicable. For cleaner cable management in dense racks, label both ends and secure excess cable to avoid strain on the connectors.
