Item Specifics HPE Aruba 50G SFP56 to SFP56 0.65m Direct Attach Copper (DAC) Cable (Part Number: R0M46A)
Overview
The HPE Aruba 50G SFP56 to SFP56 Direct Attach Copper (DAC) Cable (Part Number: R0M46A) is an enterprise-grade passive twinax copper cable designed for high-density 50GbE networking environments. Measuring 0.65 meters (approx. 2.1 feet / ~25 inches) in length, this short-reach interconnect cable provides ultra-low latency, energy-efficient data transmission between SFP56-enabled switches, routers, and enterprise servers. Engineered specifically for HPE Aruba CX series switch stacking and top-of-rack (ToR) links, it eliminates the need for optical transceivers while delivering reliable 50 Gbps throughput across short intra-rack distances.
Key Features
High-Speed 50GbE Throughput: Supports data rates up to 50 Gbps over an SFP56-to-SFP56 connection to handle high-bandwidth data center traffic.
0.65-Meter Short-Reach Length: Optimized 0.65m (2.1 ft) cable length reduces rack clutter and prevents cable strain in intra-rack or adjacent-rack links.
Passive Twinax Copper Design: Consumes zero operational power compared to optical transceivers, significantly lowering power costs and heat generation.
Plug-and-Play Compatibility: Factory-programmed EEPROM ensures seamless integration and native recognition across HPE Aruba CX Series switches.
Ultra-Low Latency Signal Path: Direct copper link provides minimal signal delay for time-sensitive, high-performance computing (HPC) and enterprise applications.
Hot-Swappable Form Factor: SFP56 connectors allow quick insertion and removal without powering down critical network hardware.
Whats Included
1x HPE Aruba 50G SFP56 to SFP56 0.65m Direct Attach Copper Cable (Part Number: R0M46A)
Ideal For
